Makeshift mini circular saw with his own hands
During repair work you may need a circular saw, which will help to make a high-quality sawing of the necessary surface. Such tools are not often needed, but they are expensive. To save your own savings, you can assemble the saw yourself. A circular saw made with our own hands will help to easily solve all the issues that arise during construction/repair.
Construction of home-built circular saw.
We assemble the saw with our own hands
Circular saw is designed for sawing logs or various wooden products. The thickness of material to be cut will depend on the power of its electric drive, t.е. The higher it is, the thicker the object can be sawn. It is possible to increase the performance of the saw not only by a powerful motor, but also by installing a camshaft.
Any circular saw consists of 2 parts. the upper and lower. In the upper part there is a working table, a saw blade and a shaft with a pulley. The lower part of the device is used to install all electrical equipment. This equipment includes:
It is better to make the frame of the cutting mechanism from metal angles 25×25 mm or 30×30 mm. The dimensions of the working table should be 650×450 mm, in the corners of which you need to weld a pipe with a diameter of 18-20 mm.
On the prepared frame of the mechanism should be fixed 2 small angles, whose length should be 20-30 mm, and the distance between them will be determined by the size of the shaft. These corners will help fix the bearings, for fixing which it is necessary to use clamps.
To improve the smooth running of the saw and improve the quality of work, you should use sealed bearings. This prevents chips and sawing debris from clogging the bearing seat.
How to make a home-built miniature saw
The simplest option for the base of the future circular saw will be a laminate, or rather, its small part, which will give stability for work and save from movements caused by vibration. Such thick material can also be used as a tabletop.
For the frame, metal linings are used, where holes are drilled in advance for the axle bearings, fixing pins and the motor. For the latter, they take a motor, for example, from a washing machine or other electrical appliances. Power of 40 watts is enough.
Belts without cross ribs are used to rotate the parts of the structure. A simple belt drive or pinion drive is all right.
The axle that holds the whole saw is made of construction studs (6 mm), mounted on two nuts. You choose the thread pitch by drilling holes for the motor mount. If the frame has oblong slots, this is ideal for adjusting the position of the propulsion device and belt tensioning.
Power supply is the element that powers the whole construction. 24 Volt is enough for simple works, more than 35 Volt is good for thick materials.
In the picture you can see that the overhang is about a centimeter. The thinner the countertop, the greater this value. 1 cm is enough for A4 plexiglass, 105 fiberglass, birch plywood, etc.

- The motor
- Adjusting side stop
- Axes
- Bearings
- Belt drive
- Engine
All parts can be found at home, in a garage or workshop, that is, there is no need to spend on consumables. Therefore, the tool with their own hands is the most budget-friendly option, which is always useful in the household.
What is a mini circular saw for?
The mini circular saw will be useful for quickly and easily sawing not very hard material. For example, wood, soft plastic or metal.
Mini wood saw allows to work with this material both lengthwise and crosswise. The circular saw can be used at an angle of 45 degrees. The equipment is used for assembling furniture, work in private workshops, etc. With it there is an opportunity to replace several other tools, because when you make it yourself, the necessary functions are added at the discretion of the master.
Thus, the saw will be suitable for working with:
An example on how to make a mini circular saw is one of many options for collecting electric tools, but it is the fastest, most economical and lightest. It is possible to create a circular saw from a motor or an old angle grinder.
A simple circular saw from an angle grinder or circular saw
Angle grinder (angle grinder). one of the most popular tools of the home craftsman, with its help it is not difficult to cut metal, clean up welds. In addition, using a disc for wood instead of the regular abrasive disc, the angle grinder can be turned into a manual circular saw (also called parquet), and by making the base with a table. in a stationary circular saw.
Required accessories
- plywood with thickness of 10 mm or more;
- switch and wire;
- countersunk head screws;
- screws;
- wooden bar 40×40 mm.
Also need to prepare a drill or electric screwdriver, hammer, screwdriver, pliers, ruler and pencil. With these tools to make your own hands circular saw.
Of course, we must not forget the angle grinder or handheld circular saw. In the first stage, it will help to cut the material, and after that it will take its place as the working body of the circular saw.
Sequence of operations
The first thing is to make the body of the circular saw. Thick plywood is a good choice for this purpose, or you can use any pressed wooden boards. Need to cut four rectangular plates, size 40 x 80 cm. You make a box with 80×80 cm square at the base. In the corners, for easy assembly and reliability of the construction, four planks are installed.
On top of the obtained box is closed with a table top. It can be made of the same plywood, but it is better to use any sheet material with a laminated coating. This guarantees the longevity of the machine, will ensure the convenience of use of homemade circular saw.
In the table top make a cut for the exit of the disk, on the sides of it drill holes for fastening the tool.
Angle grinder must be securely fixed under the table top. The design of the lock can be very diverse, it all depends on the configuration of the machine itself. The main requirement for the mount. it must securely hold the angle grinder, not allowing it to shift.
The simplest mounting can look like this: two metal angle bars, between them a steel clamp is fixed angle grinder.
For additional strength is recommended to use the thread of the side handle, it screws into it a bolt with a suitable thread.
In the upper shelves of the angles that hold the angle grinder, drill two holes. Fix the construction with countersunk screws to the tabletop from below. It remains only to block the power button, connect the angle grinder through an external switch.
In the same way you can make a circular saw with your own hands. In this case, the work is greatly simplified due to the fact that it is not necessary to invent a fastening. Enough to make a cutout for the disk, drill holes according to the holes of the plate of the hand circular saw.

Circular saw is an indispensable tool in shipbuilding.
Miniature machine from a washing machine motor
The circular saw is notable for its extreme simplicity and easy accessibility of materials. Perhaps the only expensive part is the electric motor. Stationary machines are equipped with a powerful asynchronous motor, which provides the cutting of thick wood of any species, but in the home workshop can be limited to a smaller capacity.
Please note! For sawing boards of medium thickness it is enough to make your own hands circular table with a washing machine motor drive.
This design has several advantages. The engine from an old washing machine is inexpensive, moreover, such a device is likely to be found in the household handyman. Connecting this motor is not particularly difficult, there is no need to look for schemes, engage in soldering. With all that, the power of such a unit is quite enough for most types of work.
The machine scheme can be simplified as much as possible by eliminating the belt drive. In this variant the cutting tool will be fixed directly on the motor shaft. The base of the table mini-machine is a frame, assembled from a bar section of 40 x 40 mm. If desired, it can be welded from an angle or sectional tube.
As a support (tabletop) of the circular saw, a part of an old TV set, coated chipboard, and a wooden panel are ideal. As practice shows, this part is sufficiently durable, and thanks to the lacquer coating does not prevent the workpiece from sliding.
Using an electric jigsaw perpendicular to the notch for the disk make two parallel cuts in the table top. A sliding square, which plays the role of a side stop, will slide along it. It will help to make an even cut, if necessary, at a given angle.
Circular saw with their own hands: the device, a stationary version from a circular saw
The circular saw, created with your own hands, is considered an excellent tool that is used for a variety of tasks. It is not difficult to make the device yourself. It is important to familiarize yourself with the principles of processing metal alloys.
Creating a circular saw with your own hands is considered a fairly simple procedure
Features of assembling a circular saw with their own hands from an angle grinder
Before constructing a machine, it is important to decide on its purpose. To make firewood and perform a simple sawing, it is enough to have a securely fixed table, which has a slot for the saws. But it is difficult to call such a machine safe or functional.
To perform a greater amount of work, it is worth making a circular saw, equipped with a coordinate table. It must have guides. This will help to change the degree. It is worth providing for the possibility of switching speeds and changing discs.
It is possible to make a circular saw from various devices. Almost every man has an angle grinder in his range of tools. It is often used at home. To make a stationary installation it is necessary to use a workbench or a special table. The tool must be fixed from below.
So, how to make a circular saw? To do this, you need to do the following:
- Stretch a metal band clamp on the tool. Its coupler must be placed at the bottom.
- Fold the strip of metal in half and fix it in the area of the holes.
- Make holes in the gearbox of the angle grinder.
- Attach the axial handle.
Note! The handle can be made from a metal rod or tube. In this case, the workpiece should resemble the shape of a staple.
Advantages of homemade equipment
Homemade circular saw is considered a fairly popular tool. Characterized by ease of manufacture and has a high degree of reliability.
So, a circular saw with your own hands has these advantages:
Today you can find many drawings that allow the construction of stationary or mobile saws of different sizes. To do this, you can use a drill, an angle grinder and other tools.
Some craftsmen combine a circular saw with a planer, placing them on the same base. These devices can function from a common motor. With the help of such a machine it is possible to achieve a perfect scraping of the wooden surface. Therefore, the combination of a planer with a circular saw is considered a very functional solution.
How to make a circular saw with their own hands: the preparatory stages of work
How to make a circular saw with their own hands? To do this, you need to prepare everything you need. to buy or use existing parts. Before acquiring the elements of the construction, it is necessary to make a detailed drawing. Without a diagram, it is not possible to take into account the dimensions of mechanisms and make a complete set of parts.
To make such a tool, you can use a drill or an angle grinder. Some masters make a device out of a washing machine. To make the device more functional, it can be supplemented with a lifting mechanism.
Elements of the design of the sawing machine for wood created by our own hands
The creation of a stationary circular saw with their own hands has a number of features that must be taken into account.
Making a carriage for a circular saw with their own hands
The functions and operation of the device depend on the presence of various devices. One of them is considered a carriage. To construct it, you need to do the following:
- Cut the plywood slightly wider than the table;
- At the bottom, attach the guiding bars. the interval between them should coincide with the width of the table;
- fix the thrust bars on top.
Note! In order to easily clean the coating from sawing waste, it is recommended to coat it with varnish. This material is applied in several layers.
There are several peculiarities of making a carriage
How to make a shaft for the circular saw with your own hands
The shaft is considered an important element of the circular saw. It is made of a steel round bar of grade 45. In this case the diameter of the workpiece must match the size of saw blades. The most commonly used is 32mm. It is necessary to install circular saw blades between flanges and to clamp them with nut.
In order to use the saw for working with different materials, it is necessary to provide several operating modes. That’s why it is a good idea to make several grooves on the shaft. That will make it possible to move the pulleys and change the speed.
What kind of blades for the circular saw should be used?
These elements seriously affect productivity and quality of work. The blades can be designed for metal or wood. In the first case, the discs must have small teeth. There are also universal models.
The discs can be monolithic or carbide. The first kind is made of a single piece of high-carbon steel. Such parts are reasonably priced, but have to be honed frequently. Carbide elements have a higher degree of wear resistance, but are much more expensive.
Parallel stop for the circular saw with their own hands
This is an important element for work with large workpieces. The support can be made of different materials. plywood sheets or chipboard. On average, its dimensions are no more than 25mm. You can fix the stop with boards or self-tapping screws.
To make the stop, you need to do the following:
- take 3 strips of laminated chipboard and make a U-shaped profile;
- make a guide channel from 2 slats and bolt it to the end part of the table;
- Make an inverted T-shaped structure out of fiberboard. it must be screwed to the stop and placed in the channel.
The table for the circular saw with his hands
To make a table circular saw, you need to do the following:
- Assemble from sheets of Laminated chipboard the top of the table. It resembles a box without a bottom. Fasten the fragments with bars. Their length should be greater than the height of the sheets.
- Turn the structure and fasten the bars with additional crosspieces.
- Cut out the tabletop from a plywood sheet. Use a jigsaw to make a hole lengthwise in it and place the saw blade there.
Note! To modernize the construction, a metal angle can be used instead of bars. At the bottom of the construction it is worth making a shelf.
Preparing to work
Before proceeding to work, it is necessary to determine the necessary set of tools and materials that will be needed in the process of work.
The following tools will be used for the work:
- Circular saw or you can use a sawing jigsaw.
- electric screwdriver.
- Grinding machine.
- Angle grinder (angle grinder).
- Electric jigsaw.
- Hand tools: hammer, pencil, angle.
In the process of work, you will also need the following materials:
- Laminated chipboard.
- Plywood.
- Solid pine.
- Steel tube with an inner diameter of 6-10 mm.
- Steel rod with 6-10 mm outside diameter.
- Two washers with an increased area and an inner diameter of 6-10 mm.
- Self-tapping screws.
- Carpentry glue.

- Secure the thrust blocks from above.
Note! To easily clean the coating from sawing waste it is recommended to coat it with varnish. This material is applied in several layers.
Making a carriage has a number of features
How to make a shaft for a circular saw with your own hands
The shaft is an important part of the circular saw. It is made of 45 grade steel round bar. The diameter of the workpiece must match the size of the saw blades. The most commonly used is 32 mm. The saw blades should be installed between the flanges and clamped with a nut.
To use the saw for different materials, it is necessary to provide several operating modes. Therefore, it is worth making several grooves on the shaft. It makes it possible to move the pulleys and change the speed.
What kind of blades should be used for the circular saw?
These elements have a major impact on productivity and quality of work. The discs can be designed for working metal or wood. In the first case, the circles should have small teeth. There are also universal models.
The discs can be monolithic or carbide. The first variety is made from a single piece of high-carbon steel. Such parts have an affordable price, but they have to be sharpened often. Carbide elements have a higher degree of wear resistance, but are much more expensive.
Parallel stop for the circular saw with their own hands
This is an important element for work with large workpieces. The support is acceptable to make from different materials. plywood sheets or particle board. On average, its dimensions are no more than 25 mm. Fixing the stop can be with boards or self-tapping screws.
To make a stop, you need to do the following:
- Take 3 strips of laminated chipboard and make a U-shaped profile;
- From 2 slats make a guide channel and attach it with bolts to the end part of the table;
- To make from wood-fiber board an inverted T-shaped structure. it must be screwed to the stop and placed in the channel.
Table for circular saw with your own hands
To make a table circular saw, you need to do the following:
- Assemble the top of the table from the sheets of laminated chipboard. It resembles a box without a bottom. Fasten the fragments with bars. Their length must be greater than the height of the sheets.
- Turn the structure over and fasten the joists with additional lintels.
- Cut out the table top from plywood sheet. In it you need to make a hole lengthwise with a jigsaw and place the saw blade there.
Please note! To modernize the construction, instead of bars, you can use a metal angle. At the bottom of the structure should make a shelf.
Assembling the mini-device
Before you start making a mini-saw, you need to prepare the floors in the workshop. The floor in the room must be flat, so that the saw does not sway during work, i.e.к. it does not have a heavy frame. Swinging the mechanism will not only interfere with the work process, but also can lead to various kinds of injuries.
As the bed of the mini-device you can use any old table and metal trestle. These elements should be connected with a thick board (40-50 mm).
Also, the table top can be made of 2 steel plates, the thickness of which is 4-5 mm. Good for this will suit and thick bars, which should be connected to each other plywood lintel thickness of 25 mm. A gap of 10-15 mm should be left between the sheets/blocks, it will be necessary for the passage of the saw blade.
When doing this work, it is necessary to achieve an even surface and parallelism between the inner edges of the plates. In this case it is necessary to fasten the mechanism in such a way that the circular saw is in the middle of the gap that has been prepared.
To attach the sawing element to the table, holes must be drilled on its surface. With the help of bolts you need to make its secure attachment.
Mounting the motor and finishing off
To fix the motor of the bandsaw you need a device that transmits torque. In some cases, circular saws can be mounted directly on the motor shaft, but this will reduce the power of the entire unit.
A spindle from a bicycle carriage mechanism can be used as such a mechanism that transmits the rotation. This must be cut using a metal saw. The sprocket will also be needed in further work.
Washing machine with sink included
The spindle must be fitted with a reducing sleeve, which will enable the cutting disc to be fitted tightly on it. The hub needs to be attached in several places, it can be done by welding. A metal plate with a thickness of 5-6 mm is mounted on the resulting spindle assembly. It is required to install a sprocket on the disk shaft, which will be half the size of the sprocket on the spindle. The sprockets are then connected to each other by a chain. You can use a normal bicycle chain for this. The mini circular saw is now ready and can be put into operation.
The circular saw made in such a way with your own hands will be very convenient and useful.
In order to make a mini circular saw, you need to show a little imagination and ingenuity.
All assembly work will not take much time. The resulting mechanism will speed up repair work and save money.

Making with their own hands
Circular electric wood saw can be made by yourself from all kinds of devices. But there is one important condition, namely that you must have skills to work on products made of metal.
From the angle grinder
Make yourself a stationary circular saw in the conditions of the house is not difficult. To begin with, you should decide on the project, draw a diagram and even make a drawing. The difference between the table homemade saw and a stationary saw is that the height of the base is different. Before you start assembling the tool you need to think about the “table”, i.e. the base. It should be made of wood, or rather from a board 3 cm thick, and then you need to cover everything with tin, or even a sheet of aluminum. Also suitable for similar purposes is steel sheet with a thickness up to 0.The angle is 6 cm, and the crossbars should be made of angles (up to 8 cm).
Working wheel will protrude beyond the table by about 30-35%, so for a bar with a thickness of 12 cm disc diameter should be 37 cm. The power unit you need is 1 kilowatt (or maybe more). If the blanks will be more massive, then the homemade circular saw will not be able to “take” them. The support will be made of a corner. this is a very strong and solid construction, which can withstand heavy loads. The support will extend beyond the borders of the tabletop by 4-5 cm, and one of the shelves should be machined on both sides, in which case the remainder should be equal to the length of the tabletop.
The main component will be the shaft, and it is worth to take it in a ready-made form. If you have experience on a lathe, you need to turn such a part, and it will not be difficult. You still need to buy bearings with a protective mechanism, and the pulley should take a V-belt. As the engine is suitable power unit from a washing machine or refrigerator. Capacitors are usually oil-paper. Further, when the machine will be assembled from improvised means, it will need to be tested without load, idle. All elements must necessarily “get used” to each other, so that after work in a single complex. During testing, there may be flaws that need to be corrected. For home-made circular saw is ideal for a motor from a washing machine.
Such a power unit works from a network of 220 V, has an excellent efficiency (we are talking about the coefficient of efficiency) and a normal rate of rotation. If you put a three-phase motor, which will be powered by the network in 380 V, you will need to buy capacitors, so that the unit will be reformatted to 220 V. In some cases, devices on a gasoline engine are used. such power units will have a good efficiency, as well as they are unpretentious in operation.
It is not difficult to make a circular saw from a drill, but now it is worth paying special attention to the shaft in the homemade machine. It can be turned out by yourself from metal. It is not difficult to make the element on a lathe. It is important that the centering of the part was observed, so that in the future there would be no vibration of the mechanism. Special grooves will be made on the shaft, where the pulleys and the saw discs will be attached. Occasionally, notches should be milled for the attachment of the blades. The degree of motor power is directly related to the size of the saw blade. The diameter must necessarily be 3.5 times the thickness of the product. In addition, there are proven calculations. for 11 thicknesses of material you need the power of a motor from 1 kW.
Note that craftsmen often make a circular saw with a jointer on a single base. Both tools are then powered by the same motor. Fugoval machine can grind the surface of the wood in the literal sense to a mirror shine, and its combination with a circular saw is more than appropriate.
From a circular hand saw
It will not be difficult to make a circular saw from a circular hand saw either. The slide stop can be made from angles, which will be mounted on both sides of the rotating element (disk with teeth). The width of the slit is usually up to 0.5 cm, and all edges should be trimmed so that they are slightly rounded. All corners should be made with crossbars, which should bind everything well. Bolts and nuts can be used as fasteners. A metal clamp should also be attached to the surface of the body. The screw type tie will be mounted at the bottom of the block, and the clamp with a thickness of up to 0.2 cm in conjunction with the back post will represent a failure of a single unit, which is able to withstand heavy loads. The stop will be attached to the back of the unit. The washers that make the gap can be moved, and the slots between the sidewall and the disc can be adjusted.
But the transmission is best done with a linor belt. if you accidentally hit an object, the pulleys will slip during jamming, and this eliminates the risk of injury. On the motor put a pulley with a large size, and on the shaft for the circular saw put a pulley with a smaller diameter. in such a ratio you can achieve the optimal speed.
Jigsaw or electric jigsaw? What’s the difference?
In fact, “Sabre” is an electric hacksaw, which appeared back in 1927 (of course, not in the same form as now). Suitable for cutting wooden and some metal materials, which it can do very well. Narrow and long form of the tool allows you to work in the tightest spaces. In addition, with the right blade, the Sabre cuts stone, ceramic, foam blocks, some composites, plastics and glass. Small sabre jigsaws are convenient for working from the weight.
The sabre saw and jigsaw can be called distant cousins. They are similar in many ways and at the same time they are opposites, complementing each other. That is why many people ask: “Which one is better to choose??”. One of the main differences is that the jigsaw allows you to cut oval, round and wavy profiles, while the Sabre is only available for rectangular. In addition, the jigsaw produces more precise cuts, while the rival is a kind of “destroyer”, compensating for sloppiness with speed. Obviously, both mechanisms have their advantages over each other, so it is wrong to say that one is better than the other.
But when combining these two devices, we may get something special. Let’s finally find out how to assemble this indispensable household tool by ourselves.
Advantages and disadvantages
Why bother making this home-made work if you can insert a longer saw into the jigsaw?? How the effort is justified?
Well, for one thing, even the longest saw of an electric jigsaw is inferior in size to a saw from a saber saw. This conversion makes it possible to saw thicker objects. Secondly, sawing thick enough bars is simplified by the fact that this product allows you to saw downward and away from yourself, while a jigsaw, for example, can only forward and away from yourself.
Of course, this homemade jigsaw has some disadvantages. For example, the small amplitude for a sufficiently long blade of the Sabre. The electric jigsaw has a less comfortable handle when used as a conversion equipment.
In any case, if you only need to use this tool occasionally, then it is a worthy substitute for the original, so you don’t waste your money.
How to turn an electric screwdriver or drill into a sabre saw
I once had a need for a sabre saw. Thought to take some simple, most inexpensive, but, as it turned out, there is no simple and inexpensive. start at around 4 thousand! On Ali such a nozzle can be for 1.5 find one with delivery.
In our big stores, the tools that sell, not found. If you need the saber rarely and not a lot, it is a good option. The plus is that the tool comes out wireless, which is very handy in the work. According to reviews on the Internet, it performs its functions for the price quite decent.
