How to make a circular from a hand-held circular saw
Manufacturing technology. step by step instructions
Take a sheet of plywood, mark the dimensions of the countertop. They carefully cut with an electric jigsaw, then process the edges with a milling cutter. The workpiece is sanded with medium and fine sandpaper. On the lower plane, mark a place for a circular saw: remove the disc, apply it with a sole and circle it with a pencil. A recess is chosen with a milling machine, the size of which depends on the thickness of the tool base.
The saw is installed in the place of attachment, if necessary, correct. If all fits, 4 holes with a diameter of 10 mm are drilled in the sole. Again, they apply the tool, mark the attachment points in the tabletop and make through holes. On the side of the working plane, recesses are made for M8 countersunk head bolts. The hat should hide in them. A slot is cut under the disk 1–2 mm wider than its thickness. If cutting at different angles is planned, it is made trapezoidal with the top directed downward.
They start making stiffeners with their own hands, starting with the longitudinal ones. The location is 10 cm away from the edge of the table, it is marked with lines at this distance. The boards are cut to length, applied to the countertop, and circled. A central line is marked, along which the location of the screws is indicated. The outer ones are 5 cm away from the end of the ribs, intermediate after 20 cm.
Through holes are drilled, countersinked under the caps on the front side of the countertop. The blanks are coated with wood glue, set in place, tightened with clamps. The transverse stiffeners are fixed in the same way. Fastened to the table and to each other with self-tapping screws.
The legs are shaped to provide maximum support for the frame. Usually, the height for comfortable work is 1–1.1 m. They are wider at the top and taper towards the base. To do this, one side of the bars is cut at an angle along. They will stand a bit off guard relative to the tabletop. Steel corners at the joints will help to increase the rigidity. For fastening, bolts are used, which are installed with their heads outward, put washers. Bracing from beams is also used.
Before putting the saw in place, check the position of the blade relative to the sole with a square. If it differs from the right angle, strips of tin are placed under the base on one side, achieving alignment. The circular is pulled with M10 bolts to the tabletop, the growers are placed under the nuts.
The advantages of homemade equipment
The main advantages of this technique include the following:
- Tool versatility.
- The simplicity of its manufacture.
- Possibility of significant savings.
- Equipment reliability and durability.
The schemes for the execution of stationary and mobile circulars available on the Internet and in thematic printed publications make it possible to manufacture equipment for processing both thin workpieces and thick lumber. You can pick up the simplest options that do an excellent job of processing lining, thin lamellas and plywood.
Bed based on metal profiles (angles)
The upper part of the metal frame is most conveniently made in the form of a 600 x 400mm rectangular frame welded from 25mm corners. Pipe billets with a length of 220 mm are welded to the four corners of this structure (the recommended pipe diameter is 17-20 mm).
The bed must ensure the rigidity of the machine structure
Two longitudinal angles are fixed on the frame with bolts, used to fasten the shaft in the bearing cage.
The distance between the corners is determined based on the length of the shaft, and the bearings used for installation are fixed to them with special clamps.
The lower part of the bed frame is made (welded) of 40 mm metal corners in order to make it more stable.
A closed bearing is used to mount the working shaft.
Two jumpers of the same material are welded across the frame, which are used to secure the electric motor. There is also a metal platform designed for the installation of launching equipment.
Bearings are attached to the bed with special clamps
At the corners of the resulting structure, pipe blanks are welded with a length corresponding to the size of the pipes on the upper frame, but a slightly larger diameter (23-25mm).
Closer to their edge, special clamps (lambs) are made, used to clamp the lifting pipes of the upper frame, which are moved when the drive belt is tensioned.
The procedure for assembling the mechanical part of such a machine includes the following operations:
- first, bearings 02 are taken and hammered into the working shaft with force;
- after that, on the same shaft with an interference fit is fixed a pulley, previously turned on a lathe and having an inner diameter of the groove of 50 mm;
- then a thread is cut at the end of the shaft for a bolt used to clamp the cutting tool (for more reliable fixation, it will be possible to put paronite and metal washers under the bolt);
- upon completion of this part of the work, we proceed to the installation of the drive, manufactured on the basis of a three-phase asynchronous motor with a power of 1.5 kW, (1500 rpm). A pulley is mounted on the shaft of such an engine, which has an internal groove size of about 80 mm;
- at the next stage of assembling the frame, two finished halves of the bed are connected together (while pipes of a smaller diameter are inserted into larger ones);
- at the end of the work, a belt is pulled on the shaft, and then the structure is fixed in this position by means of special clamps. “lambs”.
Features and power
The functionality of the use of equipment will depend on the correct choice of parameters, including indicators of revolutions and drive power. The power rating is influenced by the maximum permissible diameter of the serrated saw. It is believed that to process lumber with a thickness of about 10 millimeters, an electric motor with a power of 1 kW is required. Based on the thickness of the processed and sawn timber, the power of the electric motor should be chosen.
The transmission from the drive in a self-made circular is best done with a V-belt. This allows you to ensure the necessary safety in the use of technology. V-belt transmission, when foreign objects hit the saw, will slip on the pulleys, which eliminates injury and jamming of the working disc.
Pendulum engine mount
This is a more advanced circular saw. The circular pendulum suspension ensures a smooth operation of the tool, there are no jerks during operation, and the belt is tightened more tightly. Such a homemade circular saw vibrates less, which affects the quality of work and the durability of the components of the machine itself. The pendulum itself is a platform fixed on one side, on which the engine is mounted. The other end of the platform is spring loaded. When the engine is turned on, the platform dampens vibrations, and under the action of the rotation of the shaft, the electric motor tightens the belt.
As you can see, assembling a simple table saw with your own hands is relatively simple. The engine from the washing machine and the shaft from the old angle grinder are the main and most expensive parts of this machine, everything else can be made from scrap materials. The result is an irreplaceable device that, if necessary, can be modified to fit your needs by adding the necessary devices and fixtures.
How to ensure safety and emergency stop
The on-board switch on the tool is inconvenient to use when the saw is under the table. You can take it out to an accessible place by soldering longer wires. But more often they go the other way. The buttons on the circular are fixed with a coupler, a simple button for a single-phase motor is installed on the stiffener. A network is connected to it at the input, a tool at the output. In order not to cut off the plug of the cord, put an outlet. Now the circular is controlled by a button, if necessary, it stops quickly.
- 1. Littering of the workplace, instability of the structure. There should be nothing superfluous on the table, the slightest loosening is eliminated.
- 2. It is forbidden to take workpieces with your hands near the disc. When working with small parts, it is convenient to hold them with a piece of bar.
- 3. Do not use circular without a protective shield. Additionally, glasses are required so that the bounced knot or shavings do not get into the eyes.
Making a table for a manual circular is a simple task, but it requires accuracy. It is necessary to adhere exactly to the dimensions so that the parts are reliably mated, otherwise there is a danger of loosening, which is difficult to eliminate. The same length of all legs is especially important for the product to be stable.
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.
Briliant Idea DIY Mini Circular Saw with Track Guide Cut
Selection of material
To make a circular table with your own hands, you need to remember carpentry skills, stock up on a lot of patience and a small amount of materials and devices.
- plywood 15-20 millimeters;
- timber 50 × 50;
- external socket;
- a piece of cable;
- PVA glue;
- self-tapping screws.
- electric screwdriver;
The volume of the countertop will depend on the area of the workshop. At the same time, it will be uncomfortable to saw large sections on a small table. If the part fits completely on the work plane, the cut is smoother and more accurate. The height of the legs is chosen depending on the height of the master.
How to make a simple circular saw from a hand-held circular saw
Hello dear readers and homemade products!
Not every workshop has a circular machine. And in situations where you need to cut many of the same parts, it is very difficult to do without it.
In this article, the author of the YouTube channel “izzy swan” will tell you how to turn a hand (portable) circular saw into a stationary circular saw in a few minutes.
This DIY is easy to repeat using the same circular saw for which it is intended.
Materials. necessary for DIY Sheet plywood 20 mm thick. Self-tapping screws for wood with countersunk head. Plastic clamp. Titebond wood glue, sandpaper.
Manufacturing process. So, sheet plywood with a thickness of 20 mm will serve as the material for such a table. The rectangular table top is cut first from it. The most even part should be chosen, because this is the working surface of the machine.
A sheet of greater thickness should not be taken, otherwise the maximum possible overhang of the disk will decrease, and, accordingly, the thickness of the workpiece.
When sawing, the master sets the guide with the Svenson square perpendicular to the edge. You can also make such a device yourself by reading the recent article.
How To Use a Circular Saw
Instead of a guide, you can use a flat board or, as a rule, pressing it against the workpiece with a pair of clamps.
Then from the remaining trimming (parallel to the just cut edge), the author cuts out two boards of the same size, from which a parallel stop will be made.
Izzy uses a combined angled ruler to accurately position the guide across its full width.
The width of one of the strips is the future height of the stop. It should be selected depending on the thickness of the processed material on the machine.
The end of one board is coated with glue, after which both boards are connected longitudinally at a right angle. over, their lower faces must form one plane.
To strengthen the connection, you need to screw in several self-tapping screws.
Now the master returns to the very part that was made at the very beginning and has an L-shaped profile. She will perform the function of a parallel stop.
For its final assembly, the guide is pressed against the saw blade, and is attracted to it by an F-shaped clamp.
The master glues a rectangular plywood block to the bottom surface of the stop, which should rest against the edge of the tabletop. With this part, it will be convenient to align the stop parallel to the saw blade.
The resulting design fully satisfies the requirements for the stop.
Such an improvised machine tool, of course, is far from perfect. First of all, the design of the parallel stop needs to be refined to quickly and conveniently change its position. You should also modify the saw blade slot at the base, because its shape does not allow the blade to be set at an angle.
If such a table will not be used very often, then it should be protected from moisture by soaking it with linseed oil.
Thanks to the author for an easy way to make a temporary circular table for a small workshop, or for work on the road.
Good mood, good health, and interesting ideas to everyone!
Simple circular saw blade
The circular saw is considered one of the most sought-after tools for DIYers. With its help, you can trim wooden blanks, cut a bar at an angle, trim the boards in the process of laying the floor, etc. Using this tool, you can make a simple circular with your own hands.
Circular saw device
Before you start making a tool, you should familiarize yourself with the circular saw device.
- upper protective casing with a hole for ejection of sawdust;
- the body part, in which the start button and the electric motor are located;
- a lower protective casing that automatically covers the cutting element after it leaves the workpiece;
- saw blade;
- parallel stop;
- support sole of the machine;
- depth regulator;
- sole angle adjuster.
As soon as the device is connected to the mains, and the start button is pressed, the current will begin to flow to the electric motor.
Attention! Manufacturers offer a variety of models of circulars with wide functionality. Before creating a tool yourself, you can study the information on how professional tools are made.
The tabletop should also be made of metal. For this purpose, you can use steel or aluminum-based alloys. The worktop must be smooth and resistant to abrasion. It must be strong and not sag under a weight of 40-50 kg.
In the tabletop, you will need to make a groove for the disc to exit. To do this, the master must make a cut in a metal sheet.
If the master plans to professionally deal with wood processing, you should take care of the manufacture of a stationary machine in advance. Before converting a hand-held circular saw into a stationary one, it is worth creating a drawing of the unit, which allows you to choose the optimal configuration of the device.
How to make a circular saw from a hand-held circular saw with your own hands
Owners of private houses and summer cottages often think about purchasing a circular saw. However, the average Not every home craftsman can allocate such an amount from the family budget. In such a situation, you should not be upset, because if you wish, you can make a machine with your own hands from a circular saw.
With the help of a circular, you can quickly saw logs and dismantle boards
Circular Saw (Cutting a Circle Part 1)
Scope of the homemade saw
A homemade circular saw from a circular saw, allows the master to make slats / slats, sawing boards from wood materials, dissolving boards into bars. With the help of such a saw, you can easily cut off any workpiece.
Homemade products allow the home craftsman to make furniture, containers, as well as the creation of sports equipment made of wood.
Depending on which disc will be used, you need to select the motor for the circular machine. In the case of using small discs, the diameter of which does not exceed 170 mm, it is worth purchasing electric motors with a power of 0.5 kW. For larger discs, a motor over 1 kW should be used.
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 made 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.
A machine similar to factory models needs a competent attitude during the assembly process, so you need to take care of all the little things in advance. The desktop version of the “circular” differs from the stationary only in the height of the bed, which is determined by the peculiarities of work and the size of future workpieces. One-time processing can also be done using an ordinary table saw, which after work can be easily removed to the pantry or shed. But a master who constantly deals with wood will need a stationary installation. Therefore, he needs to make a table for a circular saw with his own hands.
The circular machine has the following advantages:
- Such equipment allows you to make better and deeper cuts.
- The machine is much more convenient than manual equipment.
From the foregoing, we can conclude that circular saws, made independently, have a completely understandable and simple design, and the drawings that can be found on the vastness of the World Wide Web will greatly simplify the process of assembling equipment. Before making your own “circular”, you should separately consider all the necessary elements in order to understand the nuances of the functioning and installation of homemade equipment.
How to make a circular with your hands from a hand held circular saw
If a person lives in a private house or has a garden area, the presence of a stationary circular saw in the home owner’s arsenal is not only desirable, but sometimes necessary. Unfortunately, the cost of an industrial design of such a saw does not match the frequency of its internal use, and some Russians simply cannot afford it. At the same time, you can easily make a circle with your own hands using a sewing machine drive or a regular electric drill. However, the quality of work and the range of operations performed largely depend on the base of the circular saw.
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.
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.

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 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 circulating saw, it is necessary to 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.
Despite the primitiveness of the described design, it is much easier to make it yourself to do your homework with your own hands, starting with carpentry operations with boards and ending with a cross-section of trunks cut from garden trees.
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 on your own, 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;
The finished circular saw can be positioned on a workbench. If you do not 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 “angle grinder”, it is necessary 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 an angle grinder, you can make a similar tool.
Thus, you can independently make a good circular saw out of an ordinary angle grinder, with which you can cut various materials.
