How to make a miter saw

circular

A 4×4 cm bar went to the side stops, since my saw has a maximum cutting depth of 4.3 cm.

The basis was the details in the form of a furniture board. The best option here is still a plywood sheet, since plywood has much greater strength, in the future it will not undergo deformation.

A timber was glued to the base, additional fixation is provided with self-tapping screws. The excess part of the timber is cut off.

The guides are made of 2 mm thick aluminum corners. The circular, with its weight, forced one corner to bend, therefore it was reinforced with a second one with the resulting stiffener of 4 mm thickness.

To connect the two corners, double-sided tape was used, the corners are interconnected. After that, through holes for screws are made.

The screw caps should be hidden flush so that they do not interfere with the sliding of the saw along the guides.
The side stops in thickness must be the same.

Self-tapping screws are used to fix the guides. Before each operation, we check the angle. it should be set to 90 degrees.

First, one guide is fixed. Next, a second guide is installed, the saw is taken and the distance in width is set between them, which the saw sole has.

The second guide is locked. It is necessary that the saw glides freely along the guides and at the same time it is necessary that there is no lateral play.

A cut is made along the entire length of the guide.

To make a 45-degree stop, I used another aluminum angle. it was cut to the desired length.

We choose a place for its location. We make a through hole at the base of the guide. A furniture nut is pressed into the back of the board.

Fixation is carried out using thumbscrews. The heads of the bolts are cut off and a pair of nuts and lambs are screwed on.

We make a miter saw from a circular saw

It will be useful for trimming boards, 4 cm thick bars, furniture boards up to half a meter long. Facing is possible at an angle of both 45 and 90 degrees.

What materials to make a guide

Manufacturing required the selection of materials in the form of:
furniture board 60×40 cm. 1 pc.;
aluminum corners 1.5×1.5×100 cm. 4 pcs.;
aluminum corner 4x4x50 cm. 1 pc.;
timber 4x4x100 cm. 1 pc.;
screws / screws.

The process of making a simple miter saw from a circular saw

From the saw cut, set aside an angle of 45 degrees. Another hole is drilled for fixation. The number of corners can be applied in different quantities.

An oil coating was made to protect the wood.

Finished guide.

Next. practical tests.

Trimmed furniture board.

Sawed bar. 45 degrees.

Sawed a bar with a maximum thickness of 4 cm.

Using the guide, grooves are easily made.

My beveler and circular saw have the same width of base. Therefore, the guide can work with the router together.

The easiest option is the cutting stop

The device is actively used when cutting with a jigsaw.

It works quite effectively, but it is limitedly suitable for a circular saw. The tire is pressed against the workpiece with a clamp. The bracket protrudes above the work surface both from the bottom and from the top.

As a result, we get restrictions on the length of the cut. The circular motor rests against the clamp, and you have to make a cut in two steps. In this case, the quality of the edge deteriorates, a step may form.

Any master will tell you. a high-quality cut is obtained when the saw moves continuously from the beginning to the end of the workpiece.
In industrial designs, the fasteners are placed outside the ruler, and do not interfere with the free passage of the tool.

A homemade guide is made from a ready-made tool of a different profile, which has a low cost. We buy a long aluminum rule (accent on and) for plaster or screed.

His. The tool is a profile of complex shape with a smooth groove on the reverse side for adjusting the position of the handles. Clamping fastening on hex nuts. Not suitable for our tasks.

As a donor for countersunk clamps, screwless quick-release clamps can be used, which also have a reasonable cost. Their main advantage for our design is the removable upper leg.

We delete it. At the same time, the instrument can be returned to its completeness at any time and used for its intended purpose. Instead of paws, we make and fix runners from a piece of fluoroplastic or polypropylene. The main criterion when choosing a material is strength and a low coefficient of friction.

You can process the workpiece using a router or a metal hacksaw with a fine-toothed blade. In the second case, you will have to, as they say, “finalize the file”.

We fit the sliders to the groove. Sliding should be without gripping, at the same time, a strong backlash is also not needed. There is no need to try especially, during operation this unit will be fixed.

We fasten the sliders to the top of the clamp tire. The connection must be strong, since there should be no spontaneous release during cutting, this can lead to injury or damage to the workpiece.

We check the performance of the structure. The self-made guide ruler holds securely, there is no backlash.

This design can handle flat workpieces of any size, as long as the length of the ruler is enough. In our case, it is 2 meters. Taking into account the margin at the edges for fixing the clamps. the working length is 1.5 meters. than enough for most household chores.

If your requests are longer, you can use the 2.5 or 3 meter rule. The most reasonable kit is a three-meter ruler. You can saw off a piece of 50 cm long from it, and you will have two rulers. for blanks of a large area and narrow boards.

We carry out tests. The cutting line is perfectly straight, nothing interferes with the free passage of the circular saw.

And most importantly, the purchased tool was not damaged during the manufacture of the device. Both the clamps and the rule are returned to their original state at any time and are applied as intended. Labor costs are minimal. in fact, only sliders are made.

DIY external guide rail for circular saw

While there are many advantages, the previous design has a significant disadvantage. It is necessary to constantly monitor the lateral pressure of the circular body to the ruler. If the width of the workpiece cut off during cutting is too large, the length of the arms may simply not be enough.

The way out is the use of a carriage on ball bearings. The design is not so budgetary (at least you need to buy bearings), but its capabilities cover all costs. The principle of operation can be seen in the illustration:

A carriage is made of metal plates and a corner. To adjust the width, you can use the wing clamps installed in the movable grooves.

The profile must ensure that the C-clamp is attached to the inside of the tire. You can purchase a ready-made structure from a matched pair of carriage and guide.

It all depends on the budget of the event. The sole of the hand circular is firmly attached to the carriage.

Such a tire, made by hand, allows you to cut out large-area workpieces. At the same time, the movement of the saw is light and even, the feed can be carried out both by hand and by the guide bar.

Circular saw guide. a necessary accessory to expand the capabilities of the tool

When working with a hand-held circular saw, the question of straightness of the cut arises. There are two concepts for keeping a straight line:
Fastening the actual circular to the sawing machine (workbench).

In this design, the hand tool is permanently attached to the table, and the workpiece moves along a guide. Cutting quality is at a height, but there are serious restrictions on the size of the processed material.

The workpiece is fixed permanently, and a guide fence is installed for a hand-held circular saw.

In such a design, the size of the workpiece to be cut can be any, the main thing is to provide a strong attachment for the circular saw attachment. Hand tool manufacturers have taken care of the users and offer a variety of ready-made tools for sale.

Manufactured guides are comfortable and safe. As a rule, they are equipped with an accurate ruler, some allow you to set the angle of inclination of the cutting blade.

The material is selected in such a way as to exclude wedging and backlash during the movement of the tool.

The pair, consisting of a groove and a slider, is protected from the ingress of sawn products and does not need lubrication.

DIY:Simple circular saw guide

However, all of these kits are expensive, and many DIYers make a rail for a circular saw with their own hands.

Consider the options independently invented and created by home-grown “kulibins”.

Rail miter box for manual circular

The listed designs are well suited for leisurely cutting of single surfaces. In the case when it is necessary to quickly and accurately cut a large number of boards, the work will be done slowly. Then a rail miter box is used.

For manufacturing you will need:

  • Two metal corners of the same profile and length;
  • Flat base (plywood or chipboard at least 15 mm thick);
  • One size bolts and nuts, 4 sets.

At a distance slightly larger than the thickness of the workpiece, guide corners are attached. The board must move freely under the rails, and at the same time, the saw blade cannot be too high.

We use bolts as studs. It is important to observe the parallelism and placement of the corners on the same plane. The photo clearly illustrates the operation of the device:

For free sliding of the tool sole along the guides, fluoroplastic strips can be glued to reduce friction.

But it would be more correct to install wheels. for example, ball bearings. Manufacturing is relatively labor intensive, but the system is very efficient and safe.

If it is necessary to make cuts at an angle, it is enough to screw two screws into the base into which the board will rest.

Still have questions? See the do-it-yourself circular guide rail.

Materials for making

To make a saw, you will need:

  • powerful 220 V electric motor with pulley and belt;
  • circular saw blade;
  • rod from a car shock absorber;
  • two bearings 6004;
  • two 5/8 “retaining rings;
  • metal pipes;
  • pulley ø90 mm;
  • Bulgarian;
  • welding machine;
  • hammer;
  • roulette;
  • wooden beam;
  • vice;
  • nuts, washers, screws;
  • spray paint.

Assembling a circular saw

We put the pulley on the bushing and tighten the fastening screws.

We connect the saw to the second side of the shaft in the following sequence: nut. pressure washer. saw blade. centering washer. pressure washer. nut, and tighten everything well.

We fasten the shaft legs to a wooden beam with self-tapping screws.

We install the electric motor so that its pulley and the saw pulley are in the same plane and put on the belt. Our circular saw is ready. All that remains is to turn on the power and make sure everything is done correctly.

Making the saw blade shaft

We put the bearings on the shock absorber rod. If the bearings fit tightly, we knock them out with a pipe nozzle.

Clamp the bearings together with the rod in a vice. Insert the end of the stem without thread into the drill chuck.

We mark the places of the retaining rings (in the example, the shaft length is 16 cm). Turning on the drill, we cut the grooves for the retaining rings with the grinder.

We cut off the excess part of the stem and carefully grind everything.

From a metal pipe, the inner diameter of which is slightly less than the outer diameter of the bearings, we cut off a piece of 16 cm.

We grind the inner diameter at the edges of the pipe under the bearings.

We insert the rod and bearings into the pipe, fixing them on both sides with retaining rings.

We cut out two legs for a shaft measuring 25×6 cm from sheet metal and weld them along the edges of the body from the pipe. We clean the welding places.

From a metal pipe of a suitable diameter, we make an adapter that compensates for the difference between the shaft diameter and the inner diameter of the pulley.

We weld it to the shaft and grind the edges.

Drill four mounting holes in the shaft legs.

We paint the shaft with paint from a spray can, having previously wrapped the shock absorber rod with tape.

DIY circular saw from a circular saw ?

Circular saws are firmly established in the arsenal of the craftsmen. Mainly due to the accuracy of cutting (it is much higher than that of jigsaws and chainsaws) and versatility (it can be used to make both longitudinal and transverse cuts in wood, as well as cut slate, plexiglass and plastic). If you have an electric motor on your farm, this is the right tool to think about. In our article we will tell you how to make a circular saw with your own hands from improvised means.

List of necessary tools and materials for the stop

There are two simple options for making a parallel stop with your own hands (without using bearings and other elements that complicate assembly). To select the desired structure, you should determine the needs arising from the processing of specific building materials.

For each design, you need to choose a solid rail, which will eventually move along the working area of ​​the table. To create a strong and reliable structure, it is advisable to use an extruded profile (magnesium or aluminum alloy) for assembly.

Important! The dimensions in the article will be given approximate, since they need to be selected depending on the size of the saw itself.

Assembly material

Approximate dimensions of an aluminum corner used to create a rail:

  • Wide part. 70 x 60 mm.
  • Narrow part. 41 x 10 mm.

To make a parallel stop for a circular saw with your own hands, you will need the following tools:

  • Grinder with discs for metal, which will cut off excess parts of the corner.
  • A file for cleaning cuts (it is advisable to process the metal immediately after the cut so as not to cut yourself during the assembly of the structure).
  • To mark the future workpiece, you need to use any pencil, marker and center punch.
  • An obligatory element for accurate marking of the workpiece is a tape measure or meter.
  • Use a drill to create holes in the rip fence. The master chooses the diameter of the drill independently, depending on the bolts, which he will use in the future.
  • Directly the bolts themselves, which will fasten the parts.
  • Multiple pins (8 x 18 mm).
  • Tap (M5) for threading (for the second design option).

This is the entire list of the necessary materials and tools that you will need to use to create a parallel stop at home.

What is rip fence

The rip fence (or guide rail) is a small addition to the circular saw that allows you to cut in a straight line.

In simple terms, the rip fence is a stop that holds the circular saw in one direction, preventing it from leaving the desired cut line.

Homemade rip fence for circular saw

A circular saw is a handy electric tool that greatly simplifies construction work and the process of cutting wood. The set with the equipment is supplied with various devices that make it possible to make the circular more convenient and safe to use. But some of these accessories can be made by hand so as not to spend extra money on them. The following will describe how to make a parallel emphasis for a circular at home.

Rip fence for circular saw blades

Purpose of the rip fence for a circular saw

The rip fence is designed to create even cuts (eg on plywood) parallel to the saw blade. Usually, this device is already included in the standard configuration of the circular, but there are situations when the factory version is not completely convenient for a specific use, and cannot satisfy his needs. Therefore, in practice, you have to make this device with your own hands, using simple instructions.

A natural question arises: why do manufacturers supply a circular saw with an inconvenient parallel stop? This is done for safety reasons. using a device with a standard stop, you can make cuts, the width of which is no more than 25 mm. This is to ensure that the fence does not interfere with the movement of the saw blade guard.

Important! A home-assembled rip fence will not restrict the cutting width.

Step-by-step manufacturing

The first design option is suitable for implementation if there are slots in the working table for a circular saw on both sides of the cutting blade, which are parallel to its plane. If there are no slots, then it is advisable to immediately refer to the second instruction.

To begin with, the aforementioned corner must be cut to a length of 450 mm. In order not to be mistaken with the markings, it is required to place the metal on a working table with a circular saw in such a way that the wide part of the bar is parallel to the cutting blade. The narrow plank should be placed on the table on the opposite side of the blade.

On parts of the corner with a width of 41 mm, it is necessary to mark a distance of 20 mm from the end in order to mark 3 holes with a diameter of 8 mm in the center. It is important to take into account that the distance between the holes is exactly the same, otherwise they will have to be further adjusted later to create alignment.

From the line of marked centers, it is now required to retreat 268 mm, where there will be three more through holes with a diameter of 8 mm (you need to mark with a center punch and then drill). This completes the marking process.

How to make an emphasis for a circular with your own hands. the assembly stage step by step:

  • First of all, you need to drill 6 holes, which are marked on the workpiece with a center punch. Drill diameter. 8 mm. Then, using a round file, it is necessary to carefully clean the holes to be machined so that there are no burrs. Otherwise, the master will have difficulty in the assembly process.
  • In the extreme holes, it is necessary to place previously prepared pins, measuring 8 by 18 mm.
  • What happened to be put on the work table so that the pins enter the grooves that are provided for by the design of the work table for the circular saw. Place a narrow bar perpendicularly on both sides of the working disc. It is necessary to make sure that the device runs freely on the surface of the working area of ​​the disc. The installed pins now serve as control elements that will prevent the material to be cut from shifting from a certain area. So the parallelism of the planes will not be disturbed when working with a circular saw.
  • Now you need to get close to the work table from below, and find the middle hole that was previously prepared for assembly. Between the pins, it is required to carefully place the M8 bolts so that the thread enters the slot of the tabletop, and the bolt heads rest against the lower surface. They must be placed between the pins.
  • On those parts of the bolts that will protrude from the top of the table, you need to screw the M8 wing nut and fasten it securely. Thus, a rigid connection of the entire structure with the work table will be achieved.

After assembling the structure, you can proceed to work by performing the following procedure:

  • Tighten the nuts all the way to prevent the stop from moving while working with the saw.
  • Slide the rail to a certain distance from the disc (calculated depending on the material to be cut).
  • The rack is fixed with the remaining nuts.

Now the created stop will move in a strictly defined direction, since the pins will not allow it to go to the sides. Thus, it is possible to prevent the material to be displaced relative to the cutting disc.

The work on creating a parallel stop for a circular saw with your own hands is completed. If necessary, you can also use the following design option. It will fit any desktop, whether it has grooves or not.

Important! All sizes presented in the article are approximate, since specific figures can be obtained only by studying the parameters of a circular saw that is available in the house. The numbers are easy to proportionally change depending on the specific brand of circular.

First you need to find a rail, the length of which is 700 mm. The preferred material for the corner has been indicated above. On both sides of the corner (at the ends), you need to drill several holes suitable for the M5 thread. In each of the holes, using a tap, a thread is cut.

Below is a drawing according to which you need to make two guide lines.

To do this, you need to use an equal angle corner measuring 20 by 20 mm. After cutting the material, it must be carefully filed. Now you need to find the largest planks on the corner in order to drill holes with a diameter of 5 mm there:

  • At the very top of the guide line.
  • And also one hole in the center of the bottom strip.

Once the holes are ready, you need to use the tap again to cut the threads.

The preparatory process of the guides is completed, they must be fixed with M5 bolts of 25 mm with a cylindrical or hexagonal head. It is necessary to put 25 mm M5 screws in the holes of the guides and fix them with any head.

Procedure for working with the created rip fence:

  • Loosen the screws located in the holes of the end guides.
  • The rail can now be moved to the required distance for optimal operation with equipment.
  • Once the rail is in place, each tightening screw must be securely tightened.

The rail will move along the end surfaces of the circular table, which are parallel to the working disc. Since special guides located at the ends were created, the rail will move without distortions relative to the cutting disc, and therefore it will be possible to make the most accurate cut.

Important! For visual control of the position of the stop according to the rules, it is advisable to apply markings on the table.

Tabletop small circular

This option provides for the manufacture of a machine body made of wood or an iron corner or a shaped pipe, taking into account the fact that the placement of the tool will be in a desktop version. Since the base will be small, the use of such a tool opens up new possibilities. Such a woodworking machine allows you to work in any convenient place.

The principle of creating such a machine is similar to how a hand-held circular saw is created. for the base, a body, a top plate, a fixing device for a mounting saw or a grinder are made, in the case of using a grinder as an engine.

For the convenience of work, it is recommended to make the guide bar with guides for fixing the stop in the base body, thereby increasing the reliability of the fastening. For clamping here, it is recommended to use bolts with wing nuts, thus, additionally creating convenience in work.

Complete stationary circular

A feature of such a full-fledged circular saw is its full-size housing, the ability to more accurately adjust the position of the saw, a more powerful engine and, accordingly, a longer operating mode.

Assembly technology for a stationary circular installation

To create such a tool, it is recommended to carry out work in the following sequence:

  • creation of a working sketch, general and detailed drawings;
  • markup of the main elements;
  • cutting blanks;
  • assembly of the machine frame;
  • marking and cutting out slots and holes in the working plate;
  • installation of the engine, shaft, lifting mechanism;
  • installation of electrical wiring;
  • manufacturing of additional equipment.

Table tool making

For comfortable work with machines, it is necessary to provide, in addition to the already mentioned elements, also other tools and devices necessary for normal operation:

  • for convenience, it is recommended to apply a centimeter jackal on the working plate, the “0” of which corresponds to the side of the saw blade;
  • to protect against accidental chips and chips, it is recommended to provide for the installation of a protective screen made of transparent plastic above the disc;
  • to facilitate cutting, when additional force is needed to press the board, it is recommended to consider installing a pressure roller or wooden pressure plates;
  • to facilitate the work and to prevent reverse breakdown of the board, it is necessary to provide for the installation of thrust plates.

Making the adjusting bar handle

Adjustment of the cutting depth or the height of the saw exit above the working plate is adjusted on the bed in two ways:

  • the creation of a lifting mechanism for the working plate;
  • the creation of an adjusting mechanism for raising and lowering the axles of a circular saw and a motor with a belt drive.

The lifting mechanism of the second type can be represented as:

  • guides along which the carriage moves with the shaft and the motor;
  • adjusting rod with fixing nuts;
  • handles with printed adjustment scale.

The adjusting handle can be made by welding a metal plate to the end of the stud. At a distance of 4-5 mm from the center of the plate, aligned with the center of the stud, holes are drilled for self-tapping screws.

For the convenience of work, a rod is welded to the end of the plate in such a way that the entire structure can be rotated for it.

As a scale, you can use a round washer made of multilayer plywood or plastic. it is put on a hairpin and fixed, on the one hand, with self-tapping screws, on the other, it is squeezed with a nut.

Having assembled the entire lifting mechanism, a scale is applied empirically to the plywood, corresponding to a certain lifting height of the working plate.

Required tools and materials

For the correct and reliable connection of parts, creating a rigid structure that can withstand heavy loads, you will need:

  • tools:
  • grinder with cutting wheels;
  • welding machine;
  • hammer;
  • drill with a set of drills;
  • marking tool. tape measure, meter, square, scribe, core;
  • consumables. electrodes, brushes for metal;
  • clamps, vise
  • materials:
  • metal corners or profile pipe;
  • metal sheet for the work plate;
  • bolts, washers, nuts, studs;
  • metal strip;
  • hardwood boards;

How can you make a circular?

As with the invention of the bicycle, there is no unequivocal answer, in each case it is its own unbeaten path of searches and discoveries.

But, basically, to the question of how to make a circular saw, the masters are making attempts in several directions:

  • improvement of existing hand tools, adapting them as the main parts. an electric motor and a circular saw;
  • improvement of industrially manufactured tools for specific application;
  • assembly of the machine from individual elements. shaft, engine, bed;
  • independent production of all parts of the structure, well, perhaps, except for the electric motor.

Required tools

In addition to materials, you should prepare tools.

  • pencil and marker;
  • measuring instruments including meter and tape measure;
  • jigsaw;
  • manual frezer;
  • grinding machine;
  • sandpaper (should have medium or fine grain);
  • plane and drill;
  • screwdriver.

You need to prepare everything in advance and keep it at hand throughout the entire process.

Benefits of DIY

The table is made taking into account the fact that the hand tool will be installed and fixed on the table, thus turning into stationary equipment

The construction of an element with your own hands allows you to make the saw as suitable as possible for individual conditions. Difficulties in the process will not arise if you carefully study the issue. You can adjust the product to the desired size, distribute everything so that it is convenient for you.

It is quite within the power of every master to make a table for a circular saw.

The hand-made model will be one of a kind, which makes it unique.

Small tabletop circular stand

Necessary materials

Homemade table can be made of wood

For such a table, wood, plywood or chipboard can be used. MDF and chipboard are also suitable. Some people prefer to choose steel or aluminum.

Steel plate circular machine table

It is not recommended to use plastic, it is completely unsuitable for a table of this purpose. If wood is selected, then after completion of the assembly, the product should be treated with a special antiseptic composition. This will provide reliable protection from moisture and help prevent rotting.

To make a saw table yourself, you need to prepare materials.

  • Selected raw materials for the base. The thickness should be 21 mm.
  • The beam required for the frame. An edged board with a length of 3 meters with dimensions of 50 to 150 mm is suitable. You need 5 pieces in total.
  • Dowels made of wood with dimensions of 10 cm.Not less than 12 pieces.
  • Joiner’s glue.
  • Metal fasteners in the amount of 4 pieces.
  • Metal corners. Enough 10 pieces.
  • Self-tapping screws.

These elements must be prepared in advance and placed near the workplace.

Blueprints

Scheme for making a table for a circular saw

Before starting work, it is recommended to go through the preparatory stage. Be sure to make a drawing. This will facilitate the process of creating the structure. First calculate the dimensions of the table, then transfer the obtained data to paper. The hole to be drilled in the structure must fit exactly the size of the saw. It all depends on the brand of equipment. Therefore, it is impossible to make a universal hole. The base must be stable and withstand well mechanical loads.

DIY circular table drawing

It is inadmissible to outweigh the structure to one side. The dimensions of the table top should be suitable for the cutting flow. The final version is determined based on individual desires. Some people work comfortably with a folding table or a product with small dimensions.

Drawing of a universal bench machine

An important point should be taken into account in the drawings. If you plan to leave tools or materials on the table during work, then the dimensions of the countertop need to be increased to a square meter in area. A suitable size would be 120 by 120 cm.A drawing should be done carefully and slowly in order to do everything correctly.

Circular table layout with detailed description

Deciding on the design and construction

The simplest version of a circular table is a structure made of fairly thick plywood and boards

The base can be made of wood or metal. For the countertop, leafy tree species are chosen. A special hole for the disc should be made in it. Convenience should be the key property of the created table.

Bed of the circular machine

Care should be taken to ensure its stability. Any loosening is unacceptable, otherwise it will negatively affect safety. The countertop should have the most even surface. Then the likelihood of injury during work will be reduced.

A circular saw table requires the presence of guides

The structure can be supplemented with a special riving knife. He can be filmed. It is equipped with a special disc protection, which allows it to get rid of the chips flying into the working.

Circular table guide carriage

Some remove the factory cover and exchange the factory platform for a homemade one. If you are not going to cut at an angle, you can remove the parts that adjust the inclination of the blade.

Table for a circular saw with your own hands. Drawings, photos, tips.

A circular saw is used to cut wood.

Using a hand saw is not always comfortable, using a table allows you to make the sawing process smoother and more accurate

The cutting base has a disc-like plane with a serrated outer edge. There are models not only of the manual type, but also with the possibility of fixing on the table.

It is difficult to work with large volumes of wood with a regular circular, so it is better to place it on a table.

There are several ways to acquire the latter for the convenience of performing manipulations. A table for a circular saw can be built independently, precisely following a certain pattern.

To make a quality construction, you must follow some tips. The process consists of several steps, presented in the table.

Steps Description
one The block should be trimmed on all sides using a planer. Then the frame of the future table is assembled from it. Several 5 mm holes must be drilled on each side of the countertop. Additionally, one pass-through is performed for the legs of the product.
2 Several holes of the same diameter are made in the drawers. In the legs, one through is performed. The diameter remains the same, 5 mm.
3 Proceed with installing the dowels in the table top. Before that, they are covered with wood glue. Legs and tsars are placed on top. If there are clamps with screeds, the product should be fastened with them. When the glue is completely dry, you need to fasten the drawers and legs using special metal fasteners. Additionally, it should be pulled off with self-tapping screws. You can add reliability and strength to the structure by using the corners. They will become an element of additional fastening, give stability to the product. For the short side, 2 pieces are enough, and for the long side, 3.
four The next step involves securing the saw to the workpiece from the inside. There are several methods to accomplish the task. M4 bolts or self-tapping bars are suitable for fastening. The first case is fast and reliable. The second method does not involve additional holes, which eliminates the need for drilling. It is necessary to do a drank in bars, the width of which is equal to the dimensions of the saw platform. Further, self-tapping screws and bars on both sides fasten the equipment and the tabletop
five After installing the saw, you will need another larger block. It, using self-tapping screws, is fixed on the basis of the structure. Fastening is carried out at the marks made when the platform was set in a level position. These manipulations will help, when removing the saw, return it usually quickly without looking for markings.
6 The saw blade is set in place. The base is sawn to obtain a longitudinal hole. Then the product needs to be turned over
7 Then the production of the parallel stop is started. Two strips are sawn off from the plywood. Their length should be the same as the width of the table. On average, these dimensions are 10 cm.The corners should be rounded
8 The resulting strips are sanded. They need to be fastened at an angle with self-tapping screws. A metal corner should be screwed inside
9 If you need to fix the stop on the base and the structure will be used often, you should attach the guide so that it is perpendicular to the disk. Attach the roller on the bottom. This will allow him to move.

The structure is completed and ready to use. When performing the described manipulations, it is important to remember the observance of safety measures. Also applies to any manipulation of the circular saw.

Check the position of the table and its firmness regularly. The structure must be stable, without loosening.

Table option for hand-held circular saw with lifting mechanism

Make sure the saw is securely fastened first, then turn it on. Do not hold the cut material with your hands. This will help prevent the wood from getting in your face as the knots begin to bounce. Additionally, it is recommended to use special safety glasses when working.

Be sure to wear safety glasses for safety.

These simple tips will help you avoid injury in the workplace.

assembly options for manual and stationary models

A hand-made circular saw is an excellent tool that allows you to solve a large number of household and other tasks. In fact, it is not difficult to make this device yourself, even in that situation, if you do not have any special skills, the most important thing is to understand at least a little the principle of processing metal alloys.

The materials you need for the job can be found in your home workshop or garage. So, a circular saw from a circular saw with your own hands is made from the following elements:

  • corner of strong steel;
  • rectangular shaped tube;
  • engine.

The finished circular saw can be positioned on a workbench. If you don’t have one, you will have to make the table yourself. The engine can be taken from an old walk-behind tractor or washing machine.

On the “grinder”, you need to pre-tighten the band clamp made of metal with a screw tie down. Then you need to attach the double-folded metal strip to the holes for the sliding stop. The stand and clamp can be combined, but in this situation the metal strip will be too thick.

Then, in the gearbox of the future tool, you will need to make several holes for the bolts. For this purpose, the body is disassembled, and the points where drilling will take place are indicated. With the help of the holes made, the axial handle is fixed, because the “standard” handle will not allow you to make a good cut, even if the master has very strong hands.

The handle is created from a metal tube or rod

You also need to make a barbell that will regulate the process. For this purpose, you need to take a piece of metal rod, make a loop from one end of it, rivet it slightly and make a hole for the front stop bolt.

At the other end of the rod, you need to make a thread that will allow you to connect it to the handle. In advance, one strong nut should be screwed onto this thread, and after the structure is assembled, the second. By lowering and pulling them, you can adjust the cutting depth. By the way, if you use a drill instead of a grinder, you can make a similar tool.

Thus, you can independently make a good circular saw out of an ordinary grinder, with which you can cut various materials.

Manufacturing of countertops

In the first stage of making a bed with a wooden tabletop, an existing plywood sheet is placed with your own hands in accordance with the existing pattern or pattern. To reduce the number of cuts, markings are drawn from the edges of the sheet. Use a small-toothed hacksaw or electric puzzle as a tool.

Basic design

For the safe operation of a homemade circular saw, the table must be installed on a sufficiently rigid and solid base. To do this by hand, the master’s imagination is given complete freedom. The base can be in the form of a wooden substructure, but it is better to weld from a corner (for example, an aquarium frame) in accordance with the size of the countertop.

Redesign of the Interskol circular saw into a circular saw

General characteristics of the saw Type Interskol. disc Design. Manual power. 1900 W Number of speeds.

The disc slot is marked on the underside of the piece to be cut. Dried can be done with a finger cutter, securing it with your own hands in the chuck of an electric drill. To observe the straightness of the cut edges, a simple homemade copier of two metal corners is attached to the tabletop with clamps.

To add extra stiffness to the countertops around the edges, it is advisable to fix the stiffeners, which can be made from rods or aluminum corners. Stiffeners are attached to the table using self-tapping screws. To make the entire structure more durable, a layer of epoxy glue can be applied to the joint, which fixes the bar to the top of the table along the entire plane of the joint.
The distance from the edge of the table top to the bar should be 2.0. 4.0 cm.

Thereafter, according to the selected drive structure, the circular disc support assembly is attached. For reliable fastening, it is better to fix the bearing housings to the frame with a screw, threaded connection. In this case, the secret screw heads are located on the upper plane of the table top and should not protrude above its plane. The upper working surface of the working table must be covered with a durable varnish and polished.

For greater safety when working with a homemade device, it is advisable to install a swinging fuse above the cutting edge of the blade.

Circular saw machine

To create a circular machine, you need to competently approach its assembly. Only a device thought out to the smallest detail is capable of performing the tasks assigned to it. For small jobs, of course, it is better to use a circular saw based on a hand saw (Interskol, for example). This is both compactness in size and relatively low power consumption. To process larger workpieces in large quantities, a stationary machine is required. Consider the most important components of the circular machine.

  • The table for the machine tool can be made in many ways, even from an ordinary kitchen one. The main thing that needs to be achieved is the durability and strength of the structure.
  • The working tool is a disk. It should extend beyond the table by a maximum of one third of the diameter. Best used for workpieces with a thickness of less than 150 mm, otherwise such a machine is unlikely to work.
  • Shafts and transmissions. The best solution is to install the finished shaft under the tool, since the manufacture of the shaft requires special equipment and skills in order to avoid errors and equipment failure. V-belt drive will provide greater safety and smooth running.
  • Motor. Among motors for circulars, a drive from a washing machine with its high efficiency and a longer service life is always popular.

let’s say that a homemade circular saw is capable of solving a fairly wide range of everyday tasks. The optimal and easy-to-execute option is to make a jointer and a circular saw on the same bed. Plus, both tools will rotate from the same electric motor. This feature will greatly facilitate our task. Its design will not necessarily be complicated, the main thing is to think over all the details, make drawings, carry out the correct assembly.

Attention! Always follow the safety precautions to avoid injury.!

Compact benchtop machine

The above talked about how to assemble a hand circular. Now we will tell you how to turn this device into a stationary one. This process involves the manufacture of a U-shaped bed from a pipe, as well as the installation of a transverse arm. The lower ends of the structure should bend horizontally in the direction of the cut. They are bolted to the table. Stability is ensured by additional supports.

The lever mobility is ensured by cutting the horizontal segment into two identical parts, which are fixed to each other with clamps. The saw blade is attached to the vertical element of the bed with clamps.

Frame design

The simplest circular saw frame, the drive power of which does not exceed 0.8. 12 kilowatts, is quite affordable to make thick plywood and wooden bars with your own hands. For the drive, you can use an electric drill “BOSCH GSB 19-2” (power 0.85 kilowatts) or “DWT SBM-1050” (power 1.05 kilowatts), which is attached to the plate using a special bracket. The length of the frame will depend on the length of the saw material. For the table, it is necessary to purchase bakelite plywood with a thickness of at least 50.0 mm. Of course, a wooden frame is not suitable for professional work, but in order to dissolve the boards in order to quickly cut the gratings, this homemade construction is enough.

In general, the frame will consist of a base and a table top (desktop). Of course, with a hand-held circular saw, you must strive to simplify the design as much as possible. The design of the work table will be primarily determined by the design of the attachment point of the cutting blade. Homemade circular devices use either a circular disc attached directly to the electric drill holder or, more preferably, two support shafts driven by an electric motor via a belt drive.

How to make a do-it-yourself circular shaft

In the general design of the circular shaft, the shaft is the main element that forms the whole machine. To make it, you will need steel round timber of grade 45. But you can only make this important part yourself only if you have your own lathe available or you can access it. The diameter of the workpiece must correspond to the dimensions of the saw blades to be used.

The main standard sizes of the bore of the discs:

  • 16 mm;
  • 20 mm;
  • 22 mm;
  • 30 m;
  • 32 mm;
  • 50 mm.

From the above indicators, the size of the shaft for the circular is selected.

For the manufacture of the shaft, you will need steel round timber of grade 45

The most common hole diameter is 32 mm. It is such a seat that the discs with different sizes of the outer diameter have. Alternatively, you can make a thinner shaft to be able to perform “jewelry” work. Then an adapter will be used to use large discs. In this way, it is worth complicating the design of a home circular only in those cases when it will be used by a professional.

Saw blades are installed between two flanges and pressed with a nut, which is screwed onto the thread made on the edge of the working surface of the shaft.

Important! The thread must be left-handed. During the inevitable jerk when starting the circular, the nut in this position will tighten, and not vice versa.

Bearing seats are determined taking into account the dimensions of the latter. The middle part of the shaft has the largest diameter. If the indicator is significant, an additional load on the belt will be created during rotation. To get rid of the problem, reaming will help, which will lighten the heavy part of the shaft.

The diameter of the workpiece must match the dimensions of the saw blades

Scope of application of a homemade circular saw

In the process of building a new home, when wood material is used in large quantities, a homemade circular will not be enough. And the functionality of such a device will require a wider one. But when performing repairs, a home circular machine becomes an indispensable technical assistant.

A hand-made circular saw allows you to do safe work and speed up the construction process

Quite often, the dimensions of wooden elements are determined directly in the course of work. The ability to independently provide the process with the necessary materials saves time and money to a large extent. And often the quality of wooden blanks is guaranteed to be higher.

How To Make A Homemade Table Saw With Circular Saw

On a home-made home circular, you can dissolve the boards into bars, make planks, slats, rip off workpieces, cut slabs of wood materials into fragments of the required size.

WOW! Amazing DIY Circular Saw From DC Motor

Using a homemade circular, you can make such types of furniture as a table, shelf, rack. A similar stationary home tool is applicable when creating wooden sports equipment, making containers, etc.

When installed on a saw blade with certain technical characteristics, the mechanism can be used as a circular for metal. It is allowed to saw soft aluminum and sheets of other types of metal, the thickness of which does not exceed 2 mm. When working with thicker material, the mechanism will overheat, provoking an automatic shutdown.

For cutting firewood and simply cutting pieces of wood, a firmly fixed table with a saw slot is enough

Manual circular as the basis of a homemade design

One of the most popular tools on the basis of which homemade saw designs are created at home is a circular saw (hand circular). This electromechanical mechanism makes straight cuts in wood materials as well as in soft and thin metal using a circular disc. The tool is quite simple, it has all the basic elements available that allow you to make a circular saw out of a circular saw with your own hands.

The circular saw consists of the following parts:

  • electric motor;
  • one or two handles;
  • protective casing;

Hand circulars make straight cuts in wood materials, as well as in soft and thin metal

  • holding platform (for the possibility of exposing the disc);
  • riving knife (prevents the saw blade from getting stuck in the wood).

Hand circulars stand out among other similar tools and some technical features. For example, the depth and angle of the cut can be changed directly in the course of work. Plunge-cut saws provide special opportunities. They can be used to make isolated fragment cuts of the required size.

Accuracy and quality of circular sawing depends on the number of teeth on the disc and on their sharpening angle. With a large number of teeth, the quality is higher, but productivity is slightly reduced.

When making a circular with your own hands from a hand-held circular saw, you need to pay special attention to the engine power. This is very important when intending to carry out significant amounts of work. The total weight of the saw is also important. Lightweight models suitable for occasional cuts.

The depth and angle of the cut can be changed directly during the operation of the circular

Possible options for small, hand-made circular saws

Any stationary circular, even a homemade one, requires a fairly spacious workshop. The space should allow not only to install the unit itself, but also to place the workpieces intended for cutting in the desired position. If the task is not to dissolve large wood, but simply, if necessary, you need to independently make a rail or a bar for repairing furniture, etc., it will be more rational to get a desktop circular mini-saw.

Such a device can be done by hand, using basically the same principles as when creating stationary machines from a grinder or circular saw. Only the stand will not be the goats, the support of which is the floor, but the bed, on which a small table is installed with a fixed hand tool.

Helpful advice! When making a circular of this type, it is important to take into account the overall height of the structure, that is, the plane on which the material intended for sawing will be located. Overestimation or understatement of the level will cause significant inconvenience.

The miniature machine is more functional and safer to use

If you need to create a circular mini-saw with your own hands for making workpieces of very small sizes (aircraft, ship modeling), you can assemble a tool using a PVC pipe as a body and borrowing an engine from children’s toys. In such a pipe, it is easy to make a hole for the shaft. A glue gun can be used as a joint material. Such a circular can be powered both from the mains and from a battery. To ensure autonomy of work, it is necessary to provide a special compartment for batteries in the case.

How to make a circular with your own hands: preparatory stages of work

Before you put an end to the question of the advisability of making your own circular, you need to personally get acquainted with several similar devices, watch videos on the Internet. During observations and views, special attention should be paid to the main elements, details, methods of fastening. To understand how to make a circular, you need at least theoretical knowledge.

The manufacturing process can be implemented in two ways:

  • a set of elements of the future design is available, you only need to complete the assembly;
  • the components of the circular must be purchased.

In the case of the latter option, the task becomes somewhat more complicated, since parts and mechanisms are most often bought in different places, but they must correspond in terms of technical and functional characteristics.

DIY circular making scheme

Helpful advice! It is necessary to acquire elements for the future design of the circular only after a detailed drawing of the installation has been developed.

Without a drawing, it is impossible to take into account the dimensions of the elements and select a complete set. Quite often, this stage (drawing work) is omitted by home craftsmen due to the lack of execution skill. This is not worth doing, since it is quite enough to draw a saw. At a minimum, this will make it possible to visualize the future unit. It is extremely important to imagine what will happen in the end.

Only after the drawing or sketch and all the necessary elements are available, you can proceed directly to the assembly process.

Determining the parameters of a do-it-yourself circular at home

The primary task is to choose the capacity of the future stationary circular. Usually, devices with a power of up to 850 watts are recommended for home use. If it is not supposed to carry out repair work, but to build, for example, a bath or a summer house, as a result of which it will be necessary to saw a lot of material, then a 1250 W motor can be used. A device with a higher indicator is not recommended, since such powerful circulars require not only a solid table stand, but also fixing the latter to the floor by fixing or concreting.

The cutting depth is an important characteristic. In home devices, it should not exceed 8 cm.In fact, this figure is quite enough for sawing boards, plywood or wood-based panels.

When making do-it-yourself mini circulars or a full-scale sawing structure, be sure to take into account the speed. If it is supposed to simply cut boards for the manufacture of certain wooden elements, then you can limit yourself to a motor with a low or medium frequency. If you need perfectly straight and clean cuts, then it is better to use a high-speed motor. The optimal indicator for a household power tool is considered to be a frequency of 4500 rpm.

For circular, you can use the engine from the washing machine

Be sure to take into account the height at which the trigger button will be located. The place of its placement should be convenient for pressing.

Important! The control panel of a homemade circular saw must be accessible.

Stationary circular do-it-yourself from a manual circular

The operational capabilities of a hand-held circular saw are significantly increased if it is converted into a stationary tool. To understand how to make a stationary circular from a manual circular, it is first of all worthwhile to understand the methods of rigidly attaching the power tool.

As a stand, you can use trestles made of metal or wood. It can be either one or two products (if the dimensions are small), interconnected by boards with a thickness of at least 50 mm or bars with a similar section. Next, you need to attach a tabletop to the top of the stand, which will act as a bed.

For these purposes, it is convenient to use thick plywood (at least 10-12 mm) or two sheets of thinner material joined together, which together will give the same thickness. Chipboard blades or metal are also suitable. If the metal is thin, it is better to attach it to a wooden base.

Install the hand saw from below. Preliminarily, a saw is made in the tabletop, necessary for extending the disc.

You need to attach a tabletop to the top of the stand, which will act as a bed

Important! It is necessary to fix the tool so that the saw blade is located strictly parallel to the cutting lines, that is, at the same distance from the sides. Otherwise, it will not be possible to correctly install additional devices and achieve high-quality sawing.

Using the above technical methods, you can make a circular saw from a grinder. But this hand-held power tool has certain differences, therefore, a slightly different assembly scheme will be required.

Features of assembling a circular with your own hands from a grinder

A circular saw is not found in every home workshop, but almost any owner who does certain household work with his own hands has a grinder. To create a stationary saw installation, you will also need a workbench or a special table, the tool will be attached from below, like a circular saw.

Attachment to the grinder is performed using bolts

But then the assembly process is somewhat more complicated. To make a circular out of a grinder with your own hands, as practice shows, it is necessary to think carefully about the option of attaching a hand tool to the bed. It could be the following way:

  • A metal band clamp is pulled on the grinder, the screed of which should be at the bottom.
  • Double-folded metal strip attaches to sliding stop holes.
  • Holes are made in the gearbox of the power tool. The body is pre-disassembled, the drilling sites are outlined.
  • With the help of the holes made, an additionally made axial handle is attached.

The handle can be made from a metal tube or rod. The workpiece needs to be shaped like a staple. In those places with which it will be attached to the gearbox, it is also necessary to make holes. A big and serious help for making a circular from a grinder with your own hands. drawings. They will allow you to correctly calculate the size and number of elements, to prevent mistakes when calculating the attachment points. If it is difficult to complete the diagram of the future unit on your own, you can use the ready-made drawings offered on the Internet.
