Converting a hand-held circular saw into a stationary version

The size and shape of the circular table is chosen based on the width and length of the lumber. For small boards, a one and a half meter table with a width of 60-70 cm will be optimal. The support part of a circular saw can be welded from a steel corner with a shelf width of 25-30 mm. In the upper and lower parts of the legs, horizontal struts are welded from reinforcement or a corner. This solution allows you to ensure the maximum rigidity of the frame.

For the countertop, you can use laminated particle board or OSB, plywood with a thickness of 15-20 mm. In this case, the tabletop itself does not have to be positioned symmetrically with respect to the steel support frame. When cutting a board on a circular, you have to work with both hands. With one hand, the material is fed longitudinally forward, and with the other we press the board against the table. So, the main thing is that the location of the motor and the pressure point are not very close to the edge and do not create a tipping moment for the entire structure.

The plane adjacent to the cutting tool can be covered with metal or plastic to make it easier to move the massive board around the circular saw table.

The only drawback of this alteration is the need to alter the controls: the start button and the hold lever. Most hand-held circular saws, in addition to the start button, are equipped with a lever or a hold trigger. As long as you press the trigger against the saw handle with your fingers, the engine of the device runs normally. As soon as the trigger is released, the motor stops. A very necessary thing if you unexpectedly drop a working circular saw from your hands while cutting.

Therefore, the first step is to make changes to the control system of the handheld circular saw. For this, the contacts on the button and trigger are brought out to an external electric bag attached to the body. Of course, such alterations can be performed on a power tool for which the warranty period has long expired.

In rare cases, it becomes necessary to remove the instrument from the table and use it in its original manual version. In this case, instead of soldering the contacts, the button and the trigger are fixed with a clamp or simply wrapped with electrical tape, and the power cord from the tool is included in the carrier with an on / off button.

In order to maintain the straightness of the cutting edges, a simple home-made copier of two metal corners is attached to the tabletop with clamps. Further work depends on the attachment mechanism of the circular saw blade.

The easiest way is to manually install it on two bearing supports, and the drive is carried out through a belt drive from a separate electric motor or from an electric drill.

To give additional rigidity to the tabletop along its edges, it is advisable to fix stiffening ribs, which can be made from bars or aluminum corners. Fastening of the stiffeners to the table is carried out using self-tapping screws.

To give greater strength to the entire structure, an additional layer of epoxy glue can be applied to the joint, which will fix the bar to the tabletop along the entire plane of the joint.

The distance from the edge of the countertop to the bar should be equal to 2.0 4.0 centimeters.

After that, in accordance with the selected design of the drive, the support assembly of the circular disk is attached.

For reliable fastening, it is better to fix the bearing housings to the bed using a screw, threaded connection.

In this case, the countersunk 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 should be coated with a wear-resistant varnish and polished.

For greater safety when working with a home-made device, it is advisable to install a swinging protective cover above the cutting edge of the disc.

Base design

For safe operation of a homemade circular saw, the table must be installed on a sufficiently rigid and solid base.

To make it by hand, the fantasy of the master is given complete freedom.

The base can be made in the form of a wooden underframe, but it is better to weld from a corner (such as an aquarium frame) in accordance with the dimensions of the countertop.

How to make a circular with your own hands from a hand-held circular saw

If a person lives in a private house or has a summer cottage and garden plot, then the presence of a stationary circular saw in the arsenal of a home craftsman is not only better, but sometimes it is necessary.

The simplest homemade guide rail for a circular saw or Do it yourself. Unfortunately, the price of an industrially made standard for such a saw does not correspond to the frequency of its use at home, and for some Russians it is simply not in the

At the same time, making a “circular” with your own hands is quite simple, using a sewing machine drive or an ordinary electric drill. Selection of a saw blade for a circular saw blade. Disc needed for 190mm disc selection for.

But the quality of work and the range of operations performed in almost everything depend on the frame of the circular saw.

Building a home circular

For your information! The main advantage of the above circular saw scheme is a well-chosen engine torque and speed, which ensure the maximum performance of the device.

On a disc with a diameter of 225 mm, the overhang or height of the disc above the worktable is only 40 mm. This is more than enough to cut a forty board into a strip or strip, cut out any curly details and solid wood. In addition, a spring-loaded protective cover is installed on the body of the circular, which covers the cutting edge in the inoperative position.

Perhaps this device is useful and necessary for protecting fingers and hands, but it only interferes with the work, since the thin cutting edge of the disc is not visible. Therefore, when altering it, it is often dismantled or fixed on the body of the circular saw in the open position.

Some of the nuances of manufacturing

The main parameter that determines the design of a homemade “circular” is the thickness of the boards being sawn. A circular circular saw is a circular hand saw for sawing boards, like.

For DIY household work, it is usually not required to saw wood thicker than 15.0 20.0 millimeters.

To change the cutting depth, you can use and / or make a special disc lifting mechanism, but this will significantly complicate the design of the homemade product.

Using a belt drive, you can make a change in the number of revolutions with your own hands.

If it is supposed to use an electric drill as a drive, then preference should be given to models with a variable chuck rotation frequency, then it will be a pleasure to use such a hand-made circular saw.

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;
  • angle grinder;
  • welding machine;
  • a 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.

DIY circular saw from a circular saw ?

Circular saws are firmly established in the arsenal of the craftsmen. Mainly due to the accuracy of sawing (it is much higher than that of jigsaws and chainsaws) and versatility (it can 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 available tools.

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.

We 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, use an angle grinder to cut the grooves for the retaining rings.

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 25×6 cm shaft 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.

Circular do-it-yourself: how to properly assemble a functional device

“I have long dreamed of having a circular at home”. many posts in social networks begin with these or approximately the same words. And then follows information about how the circular was made with your own hands. Quite a logical sequence of actions. An artisan person who is ready to use such a tool on his own is able to assemble it. How to do this. in the materials of this article.

A hand-made saw has a number of advantages

Making a carriage for a circular do-it-yourself

The functionality and high-quality operation of a stationary circular is largely influenced by the availability of devices. One of these is the carriage. It is completely easy to do it at home, but the implementation of facing and sawing off material at an angle of 45 ° will be much easier.

You can make this device for circulars from a sheet of plywood as follows:

  • plywood is cut out a bit wider than the circular table;

The carriage for the circular can be made with your own hands

  • in the lower part, guide bars are attached to it with glue or screws, the distance between which should be equal to the width of the table;
  • from above in a similar way, using screws or glue, thrust bars are fixed.

With the help of guides, the carriage is fed along the table onto the saw blade, which makes a through cut on the device. The height of the sides, which should be larger than the protruding saw blade, allows you to maintain the integrity and rigidity of the carriage. If the task is to cut at an angle of 45 °, it is necessary to use an additional bar, which in this device is a removable element. Cutting is done by pressing the workpiece against an angled bar.

In order for the plywood surface of the carriage to be easily cleaned of sawing waste, it must be varnished in several layers.

The plywood should be slightly wider than the circular table

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 stand-table, but also fixing the latter to the floor by fixing or concreting.

The cutting depth is an important characteristic. In household 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 rotational 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.

Making a do-it-yourself circular trimmer

Laying a wooden floor, replacing platbands, cladding the facade with planken, clapboard, creating landscape design elements require a dimensional board. The process of preparing such a board is called facing. That is, the ends of the material are cut off in order to obtain the desired size of the workpiece and make the cuts aesthetically pleasing.

Do-it-yourself trimming makes work faster and more economical

To make a trimming from a manual circular with your own hands, you will need an improvised material and a used tool. The standard characteristics that the future trimming should have are as follows:

  • maximum cutting length. 350 mm;
  • optimal engine revolving power. 4500 rpm;
  • insignificant weight.

The upper part of the power tool is attached to the pivot using a large bearing. 150 mm (it will not be difficult to purchase it on the market.) On the outside, ears are attached to the bearing. They are used to fasten the tool to the surface of the bed using M6 screws.

The main devices for do-it-yourself circulars are automobile shock absorbers (they are convenient to use as a broach), a soft start button and additional protection that is attached to the power tool and the bed.

The upper part of the facing is attached to the pivot using a bearing

Important! Before assembling the structure, the shock absorbers must be disassembled, oil drained and air holes must be made.

The advantages of a homemade miter saw include the following:

  • The structure is easily disassembled, and the power tool can be used for its intended purpose.
  • Small

Among the significant disadvantages, it is worth highlighting the high noise level. It is almost impossible to eliminate this drawback. In addition, it is necessary to do a trial cut (selection and fixing of the traction) to ensure a good quality of subsequent work.

Which discs should be used for circular

The performance and quality of work to a large extent depends on a properly selected disc for a do-it-yourself circular from an angle grinder, hand saw or assembled from separate mechanisms. It should be remembered that discs for wood and metal differ. Even if thin, soft aluminum is to be sawn, a suitable blade must be fitted. Cutting wheels have smaller teeth. There are universal disc options that are applicable to work with both wood and metal.

There are differences and discs designed for longitudinal and cross-cutting wood. Rip sawing is carried out with a cutting attachment with large sparse teeth. But transverse cutting will be of better quality in the case of using discs with fine, frequent teeth.

As for the material and method of manufacturing the discs, they can be monolithic and carbide. Monolithic are made from a single piece of high-carbon steel. Such nozzles are inexpensive, but at the same time have a significant drawback: they quickly become dull and need sharpening and wiring.

Circular discs can be for wood and metal

Carbide wheels are made from cobalt and tungsten-tipped tool steel. They are more durable, but the price for such products is much higher.

The outer diameter of the discs for a homemade circular is limited by the size of the protective casing. The standard disc thickness is 3.2 mm. There are thinner and thicker saw blades. Thin ones are used when working with wood of valuable tree species to make a clean cut. For coarser work, thicker discs are recommended.

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 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 an angle grinder. But this hand-held power tool has certain differences, therefore, a slightly different assembly scheme will be required.

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 detail 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.

To make a shaft, you need steel round timber of grade 45

The most common hole 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 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 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
