Making a circular from a hand-held circular saw
A circular saw is quite simple to make from a hand one. It is not necessary to change the design of the original tool. The whole point is in making a table on which the circular saw will be attached from the back side. The sawing hole for the disc will be made in advance. Let’s consider the process in stages:
- The table top with a smooth and even surface is cut from plywood. A hole has already been made in it for the disc and for the saw mounts.
- The hand tool is attached to the underside of the table with bolts, the heads of which must be recessed into the plywood.
- In order not to make structural changes to the original tool, its button must be fixed in the working position, and the switch must be connected to the socket.
How to make a circular saw with your own hands?
A circular saw will always help to cope with many household and construction tasks. Making it yourself is not as difficult as it seems at first glance. It is enough to adhere to simple rules in working with metal, to have suitable materials at home or in the garage. If you briefly describe the design, then you need to do the following: you will have to build a workbench for a saw of the required dimensions and adapt a hand-held circular saw for it. A stationary machine of this type will greatly facilitate the work and increase its volume. So, let’s look at how to make this tool yourself.
Home circular saw bench
Such a frame can be made in a domestic environment. There are two versions of the drive with a power not exceeding 1.2 kW. This is done in order to exclude increased power consumption. The structure of the first drive may include an electric drill of the specified power. This design is ideal for the home, but for professional work, its use will no longer be appropriate.
The bed consists of a work table and a base. To simplify the mechanism, you need to achieve this as much as possible in the disk mount. There are three main options: a hand-held circular saw on a tabletop, a connection between a blade and an electric saw chuck, shafts driven by a motor.
The table must have a solid and rigid base to ensure safe operation. In everyday life, there can be many options, it all depends on the author’s imagination. An important design parameter will be the cutting thickness of the workpieces.
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. It is best used for processing workpieces less than 150 mm thick, 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.
When selecting an engine, it is imperative to pay attention to the shaft speed. You can, if desired, independently change the number of revolutions using a belt drive. The motor must be powerful enough, so you do not need to save several thousand and make it from the first thing that comes to hand, be it a drill or a mixer.
The main indicator of a homemade circular saw is the maximum thickness of the sawn bars. Usually, for home use, a cut of 1.5-2 cm is enough, but if this is not enough, then an additional lifting disc mechanism can be installed. This will make the system more complex, but will allow you to deepen the cut to the required level.
How to make a circular saw out of a circular saw. instructions
Any owner of a private house or summer cottage has ever necessarily thought about purchasing a stationary circular saw. However, in most cases, the purchase is postponed indefinitely: the cost of such pleasure exceeds two or three tens of thousands, which is often beyond the means of an average citizen of the country.
But even if you are not ready to spend that kind of money on a stationary saw, you can make one yourself from a hand-held circular saw. For professional use, such an invention may not be suitable, but dissolve the boards, quickly and conveniently saw the beams or sheets. Fiberboard is quite real.
To make a homemade circular, you will need:
- Washers, nuts, bolts;
- Metal strip;
- angle grinder;
- Metal corner;
- Old table or thick sheet Fiberboard;
In the question of how to make a circular saw out of a circular saw, the most important thing is to remember the functionality of the base. It is best to install the table on a high-quality and rigid base that does not bend or wobble. This ensures safe working and an even cut.
If possible, it will be good to weld it from a metal corner in accordance with the dimensions of the finished tabletop. In extreme cases, it is permissible to build a base like a wooden underframe.
It should be remembered that such a stationary circular is still made by hand. Therefore, in order to avoid injury, it is better to secure your work as much as possible. You can install protection in the form of a special movable casing located above the edge of the disc.

It is also best not to make a circular with a drill. Although many craftsmen advise this method due to its simplicity and economy, at the slightest mistake, serious injury cannot be avoided.
Bed for circular saw
The most common bed can be made from an old dining table or thick wood plywood and a few slabs. Holes are drilled in the tabletop to fix the circular itself and an incision is made according to the size of the saw blade. It is important that the bed cover is not made of thin material and that it can withstand the load of the workpieces. For fastening, it is recommended to take countersunk screws so that they do not protrude above the surface and do not catch the material during processing.
It may seem that the design is too simple and uncomplicated, but this does not detract from the merits of such a primitive circular. It, just like its factory counterparts, does an excellent job of sawing small wooden blocks and allows you to perform carpentry operations with boards.
By the way, your homemade machine can be made multifunctional and you can also attach a plane to it. This saves space and makes the tools easy to dismantle.
Circular from a hand-held circular saw with your own hands
The hand-held circular saw, commonly referred to as the “angle grinder”, is a very useful and important tool in the home workshop. With its help, you can easily cut a board or metal, any other modern lumber of various sections. Also, an angle grinder can cut at any angle, climb into hard-to-reach places, and so on. However, despite its mobility, the circular saw can be used as a stationary circular saw. But, in order to make such a machine, it is necessary to make a special structure from previously prepared materials. So, you need to make a table on which all sawing work will be carried out. The frame can be made using the simplest wooden trestles, interconnected by several pieces (45-50 mm each) of the board.
What the machine frame consists of: 1- goats; 2- support boards
On the resulting base, you will need to fix the work surface. the table. This surface can be made from various materials. boards or steel sheets, metal plates, and so on. In general, make a table with what you have in stock. In this case, the dimensions of each plate should be about 150-200 m in width, and 4 mm or slightly more in thickness. When fixing the working surface, they need to be tied together using plywood jumpers, about 25 mm thick. Also, check that the width of the gap between the plates is about 12 mm, and parallelism must also be observed along the entire gap.
Circular working table: 1- plywood lintel; 2- steel (plywood) plate; 3- insert; 4. circular disc; 5- fixing screws; 6- screws; 7- support board
Now for the installation of a hand-held circular saw. It must be secured to the bottom of the table so that the saw blade is positioned right in the middle of the gap so that it is parallel to the sides of the table. Naturally, this is necessary for normal rotation of the cutting blade. In order to fix the saw in a fixed position, the required number of holes must be drilled in the work table and base plate in advance. At the same time, the surface of the table must remain smooth, therefore, for this, the front side of the base plate is countersunk, tightening the entire assembly with screws and countersunk heads. Now that the work table is ready, it can be screwed to the bed using screws and screws and nuts. Make sure the machine is as flat as possible. Otherwise, if the table is screwed on incorrectly, the machine will stagger, and you will constantly have to adjust some object under it. In the gap between the plates, insert an insert with a slot for the saw blade. Well, the circular machine is almost ready and can start working. When cutting materials, do not forget to fasten the stop bar to the table with clamps.
A useful and practical addition to your circular saw can be a miter carriage. With its help, the work on trimming the workpieces is greatly simplified, by sawing them “on the mustache”, that is, at an angle of 45 °. Immediately, we note that its design is extremely simple, and it will be much easier to manufacture it than to work without it.
So, prepare a plywood sheet, guide bars and a box of bolts and screws. Glue the guide bars on the surface of the sheet, and then screw them in with screws. The distance between the bars should correspond to the width of the homemade machine table. In the same way, you need to install the stop bolts from above. The carriage is installed on the table, and during the operation of the machine, it is fed along the guides towards the disk, making a through cut of the entire workpiece. And due to the fact that the sides have more exit than the saw blade, the miter carriage will maintain sufficient rigidity.
Miter carriage: 1- guides; 2- plywood sheet; 3-cut; 4- sides for emphasis; 5- removable bar
Thus, the workpieces are butted, pressing against the side and moving longitudinally along the table. And in order to make a 45 ° connection, you need to use a removable bar. It must be installed at a predetermined angle, then press the workpiece and perform the necessary operation.
about tools, machines and equipment:
Manual device from angle grinder
A lot of work is done with the popular angle grinder tool. From this tool you will get an indispensable circular saw made by yourself. It is enough to make a sliding stop from the material at hand. The design assumes the presence of two small segments of the corners, which are located parallel to the disc. The connection is made using bolts, the clearance is adjusted with the supplied washers.
Install the strap clamp so that the screw is at the bottom. Next, a strip of metal with a hole is attached, in another case, the structure can be single, but this is how the thickness of the metal is lost. The next step is to cut the holes in the body through which the handle is attached for basic work. A hand-made handle is a horn or bracket, a metal rod or pipe is taken as a basis. Riveting should also be taken into account, if the ends are relaxed, the handle may bend during mechanical action on it.
There are several types of gears that can be used in a do-it-yourself circular design:
- V-belt transmission;
- gear mechanism.
The preferred option is the use of a belt drive. Using a gear mechanism can lead to seizure by foreign bodies and injury to the worker. When choosing the diameter of the pulley, the maximum number of revolutions of the saw blade is taken into account.
Design features of the circular machine
Circulars of any fixed type consist of main parts.

- A table for connecting mechanisms. An assembly compatible with larger motors is preferred with an all-metal table. The surface of the table must be made even with your own hands, for a better product at the exit.
- In most cases, the engine is used from what is in stock. Electric motors designed for long operating time from the mains will be preferable to collector drives.
- The shaft is the most critical unit of the circular. Finished products are used most often, in other cases the assembly is made on a lathe. It is important to calculate the bore holes, to exclude runout.
When making a machine with your own hands, you should pay special attention to safety. The main cleaning of the saw blade must be covered by a protective cover. The moving parts of the drive and motors must be covered. Emergency stop button is built into the drive circuit and has a convenient location.
The design of the do-it-yourself circular should contain a saw blade. The working surface of the disc is set at a third of the total diameter. For example, with a diameter of 210 mm, the disc should protrude 70 mm from the table. Parts with greater thickness will require a powerful motor, from 1 kW. A miniature circular saw cannot handle this task.
The splitting knife installed on some models serves to prevent short circuits and seizure during operation. Located at the rear a few millimeters from the saw blade teeth. The device may also be needed when making a circular with your own hands.
Circular do it yourself
In the household, a circular saw always comes in handy. Overhaul is a costly and troublesome business. Not everyone can afford to buy an expensive tool for processing wood materials. A hand-made circular saw allows you to perform safe work and speed up the construction process. A hand-made saw has a number of advantages, such as reliability, economy and sharpening for immediate needs.
Purpose of the circular saw
Before you start assembling the machine, you need to clearly define its purpose. A firmly fixed table with a saw slot is enough for harvesting firewood and simply cutting large pieces of wood. This type is common in villages and rural areas, the machines do not differ in safety and increased functionality.
For more varied Spectra joinery jobs, you will need a better option. The circular must be equipped with a coordinate table with special guides, this allows you to change the degree. Manufacturing small items requires increased safety. Speed control is set, disc change is provided.
Desktop Miniature Circular Machine
The stationary machine is more functional and safer to use. A homemade tabletop circular is made at home in the same way as a hand saw, with the addition of some elements. A homemade circular saw with your own hands will require prepared drawings. The process involves the use of a 2 cm pipe, the metal is bent in a U-shaped shape. The mount is bolted to the table, the lower ends are bent in the direction of work. Additional stability is gained through the installation of a lever with a jumper, sealed by welding in the shape of the letter “T”.
A table for a do-it-yourself table saw can be used as a cutting machine. The cut cannot exceed 8 cm, so larger work will require a larger machine.
