How To Make A Circular Saw From A Circular Saw
Fragments of chipboard or thick plywood should be fastened to the table surface relative to the slot with self-tapping screws, increasing them, screwing them to each other, to the previously measured level of the circular saw positioning height.
It should be noted that at the very last level a layer of chipboard will go, which will form a shelf for the movement of the circular saw. So, increasing the height, you should remember about the thickness of the chipboard of the last layer.
The shelf for circular movement consists of two parts, symmetrically located relative to the mowing line, the cut for free movement of the disc. In fact, you should get 2 “bridges”, set parallel to each other through the space for the saw blade and the right edge of the table on the very right side of this table.
Step by step guide
Let’s analyze the sequence of actions when converting a circular into a miter saw. The peculiarity of the “parquet” is its characteristic course. You need to move it along the surface of the material being cut, but not vertically. Therefore, the machine will represent their basis, which, firstly, will allow positioning and fixing the workpiece, and secondly, it has a base with stops along which the circular saw will move in the device (parquet floor).
Required materials and tools
First you need to decide on a project. Above, attention was paid to what the miter saw can be constructed from:
- The most technologically advanced and affordable material is sheet wood-containing materials. They are easy to cut to the required dimensions using the same existing parquet (part of the future machine);
- The frame structure of the bed with elements of chipboard or plywood is more difficult and more expensive to implement, and therefore is not always justified;
- Self-tapping screws will be required.
In addition to construction materials, the following elements will be needed to design a trimming device:
- Clamps (2 pcs.);
- Circular saw (“parquet”).
If a technology is chosen for the production of a bed that does not contain steel parts and elements, then in this case the tools will require:
- Set of screwdrivers;
- Hacksaw (for auxiliary purposes, when it will be inconvenient to use the existing “parquet”).
It’s amazing how little it takes to build a DIY miter saw.
Aligning workpiece guides
It should be a strip of chipboard or thick plywood, only here it is no less than 10 cm wide, since it will have a much greater length. the guide should be 20% longer than the table, so that it is always possible to fix it with a clamp in two places. It is installed closer to the front edge of the table at the desired angle to the saw blade slot, and secured with clamps.
It is not necessary to fix the guide on the self-tapping screws at all, since in this case it will be impossible to adjust the cutting angle if necessary. The guide for the blanks, of course, should be one, since the second simply cannot be fixed with a clamp in 2 places. When working on such a facing, the workpiece must be tightly pressed against the previously fixed guide with one hand, and with the other (right) cut the workpiece with a circular saw.
Determining the height of the shelf for lateral movement
If the machine is right-handed, then the shelf for the circular saw should be located on the right edge of the table in order to be able to fix the workpiece on the table.
Adjust the protrusion on the circular saw to the maximum and measure at what height above the table you need to position the shelf for the circular movement of the circular so that the teeth of its saw blade do not touch the table. This measurement will actually determine the maximum thickness of the workpieces.
How to assemble a stationary circular saw
For more convenient work with the machine, the craftsman made a movable stop on the furniture rails.
Aluminum corner served as a longitudinal stop.
To adjust it, loosen the bolts and move it to the distance required for further work.
However, in this position, the saws will be lost 10-20 mm.
Universal saw table for circular saw
So, id215711128 has a powerful circular that is more than 20 years old. Saw cutting depth 65 mm. In the course of its operation, it turned out that it is difficult to achieve high-quality sawing of wood with its help. Reasons: the settings for the angle of inclination of the blade and the depth of cut are constantly getting lost. The saw sole is made of thin metal, as a result, it bends, and the geometry is not maintained when cutting the workpiece.
At first, the user went the standard way. he began to modify the saw. Manufactured devices to ensure the perpendicularity of the cut. I put wedges to maintain the cutting depth. I built the saw into the table, as it is, but the frail M4 thread, on the circular racks, weakened and each new passage had to be adjusted anew. Despite the difficulty of sawing, id215711128 produced 5 casing boxes. The “accident” that gave impetus to the construction of a multifunctional sawing table occurred when a craftsman was making sidewalls for casing the door.
I sawed a two-meter beam. I have already chosen quarters, cut the locks, it remains to choose a longitudinal groove, designed to fix the product on the wall. I made several cuts with a saw, and when the workpiece was almost ready, the depth of the circular was lost. I practically sawed the bar in half, completely ruining the part. That’s it, on this I realized that I had enough of these “dances with a tambourine”, and I need a normal sawing table.
First, the user bought plywood for the countertop in a construction hypermarket. Then he developed a technical assignment, what requirements the table should meet. So:
- You need the largest possible saw blade overhang.
- The saw blade must have an adjustable angle of inclination. 90-45 degrees and an overhang of 0. max with reliable fixation of the specified parameters.
- Large section parts must fit on the table, therefore the dimensions of the table are 1.22 x1 m.
- You need an adjustable and securely fixed rip fence, as well as adjustable horizontal and vertical clamps for workpieces.
- The table must be multifunctional, with the possibility of further installation of a router and an electric jigsaw.
On the topic “universal carpentry accessories” we recommend reading the articles: homemade workbench-assembly table and universal folding trunks.
Having decided on the requirements, id215711128 thought about what to make a mechanism for raising and lowering the saw. The choice fell on an automobile screw rhombic jack.
Then came the turn of the circular upgrade. From it, the user removed the sole, the saw blade cover, because She got in the way, and disk protection. The saw was disassembled with the expectation that, if necessary, it could be reassembled. I installed the saw on a lift.
The saw is tilted using a homemade swivel mechanism made of hairpin and planks.
According to the DIYer, because of the metric thread, the handles have to be rotated a large number of revolutions, but with infrequent machine readjustments, this is not critical.
The rip fence is 1220 mm long. To exclude the shift of the far edge of the workpiece when cutting it, the stop is equipped with an additional lock.
Machine tests have shown that everything works as it should. Angles of inclination and cutting depth are not lost.
At this stage, the user took time out and thought about how to upgrade the machine for sawing large workpieces. It came to mind to make a carriage, but it will “eat” about 1 cm of the cut depth. This can be critical, since K. The details of the casing boxes are made of a bar and have dimensions of 1.5-2 m, with a section of 10×20 cm. In addition, such a bar weighs a lot, and it is inconvenient to push it on the table. Exit. the workpiece is in place, and the saw itself moves.
I remembered that when in a construction hypermarket they sawed plywood for me, they did it with such a “tricky” machine, the saw blade of which moves from top to bottom and from left to right. On reflection, I decided to make a cart with rollers and correcting rollers, along which the saw will move.
To make the device, the user bought rollers for a furniture trolley and a 5×5 cm corner. At first, id215711128 decided to install only the lower and horizontal rollers. But, since K. Due to the application of forces when moving the trolley, it may be skewed, the master put additional rollers on the trolley, which abut against the lower surface of the tabletop.
During the “running-in” of the table, it was necessary to adjust the coaxiality of the cutting direction and the direction of movement of the cart.
For this, washers were placed under the fastening of the guide corners.
Having adjusted the machine, the DIYer tested it by sawing a board with a section of 20×5 cm.
Taking a simple circular as a basis, I managed to make a sawing and miter saw with the possibility of longitudinal and cross cutting. You can saw either by rigidly fixing the circular, moving the workpiece, or moving the saw, with the workpiece clamped by the clamps with adjustable depth and disc inclination. I plan to further refine the machine to make it even more functional and more convenient. To do this, you need to put:
- Quick-release fixed stop with protractor for facing workpieces at any desired angle when moving the saw.
- Movable protractor for processing small wooden products with fixed circular.
Also, the user installed an eccentric clamp to fix the carriage in any of the saw positions.
To maintain the positioning of the tabletop relative to the underframe when removing the saw unit and trolley, screwed in two pins that fall into the holes in the tabletop.
Also made a cross-cut carriage.
With a stationary saw, the carriage moves perpendicularly due to metal profiles (U-shaped and square) mounted in the tabletop, sliding in each other.
When screwing in the knob, the carriage is fixed. Now the circular saw blade cuts the workpiece resting on the carriage.
Additionally, a recess is made in the tabletop for attaching a hand router.
The tool is attached using the pins that come with it.
So that the handles of the milling cutter do not rest against the fasteners, they will have to be finalized, and the tool will also be raised and lowered by an “elevator” made of a clamp by analogy with a circular saw lifter.

How to make a circular saw from a circular saw
Crosscutting is a device for cross-cutting a product along the length, and not only wooden materials, but also any other that can be cut by circular saws (for example, plastic). There is a sufficient number of hand-held circular saws on the market (the so-called parquet floors), with which you can:
- Customize molded products;
- Remove excess material by cutting out blanks;
- Or even make long rip cuts.
But these machines are very expensive. And besides, as a rule, the need for them is never long-term, unless you are professionally engaged in carpentry. In this case, it makes sense to build a homemade miter saw using an existing hand-held circular saw. But how to properly make a homemade miter saw from a circular one? We will talk about this on the pages of this article.
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 number of materials and devices.
- Plywood 15-20 millimeters;
- Bar 50 × 50;
- External socket;
- A piece of cable;
- PVA glue;
- Self-tapping screws.
- Electric jigsaw;
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.
Step by step assembly
You can make a stationary circular saw with your own hands from an angle grinder and a hand cutter without making any changes to the design of the working tool. The base is made of sawn timber, which makes it possible to significantly simplify the manufacture, eliminating the need to use complex welding equipment. Step-by-step instruction:
- The base is made of a bar with dimensions of 40 by 40 millimeters and plywood sheets.
- The table top is made of varnished or laminated plywood. A cut is made in the center of the tabletop, into which the cutting disc will enter.
- From below, using bolts or other fasteners, fix the circular saw.
- A switch is installed that allows you to turn on the saw without raising the tabletop. You can also make a circular without a switch, for which the working saw is switched to the “On” mode, and then all that remains is to apply voltage to the tool.
- From furniture guides, you can make a movable stop, which is attached with corners to the wall of the circular opposite from the switch. The presence of such a stop allows you to significantly simplify the cutting of wood.
- The longitudinal stop is made from a metal corner, and its movement is carried out by loosening the bolts. The fixing bolts are located in the small parallel cuts of the table top.
- It remains to conduct a test run of the tool and, if necessary, perform its adjustment.
This option for making a circular saw will be an excellent choice if you need a tool for cutting boards up to 3 centimeters thick. If you need to make a powerful and multifunctional device for the home, then use electric motors with a power of 5 kW or more, which allow you to process and saw boards 5-8 centimeters thick.
Some craftsmen make more complex tools, involving the use of powerful electric motors, V-belt transmission and larger diameter saw blades. If you have any difficulties in the network, you can find thematic ones. Telling about how to make a circular with your own hands.
The work on the manufacture of this part of the equipment is carried out in the following sequence: We begin by marking a piece of plywood, carried out so that its edges are flush with the edges of the prepared sheet of iron. After marking, using a hacksaw or electric jigsaw, you can cut the plywood blank to the required size. If desired, it will be possible to process its edges with a cutter, although this is not at all necessary (the main requirement for this element is its reliability, not attractiveness).
Upon completion of these operations, the surface of the countertop is carefully processed (rubbed over) with medium-grain emery cloth.
Then, on its lower part, the location of the slot for the saw blade is preliminarily marked. To do this, it is necessary to determine the dimensions of the sole of the circular saw prepared for installation. For the convenience of taking measurements, the saw blade is simply removed from the saw, after which it will be possible to easily determine the dimensions of the seat.
For the convenience of marking the tabletop, the saw blade is removed
Upon completion of its preparation, you should take a circular saw and try it on at the installation site. If necessary, the position of its attachment points is adjusted (at the same time, the contours of the slot for the saw blade are refined).
The finished plywood tabletop is closed with a steel sheet fixed to it with self-tapping screws. Subsequently, it will be possible to apply a special marking on the working surface, which allows you to correct the position of the wood blank during its processing.
Features and power
The functionality of the use of equipment will depend on the correctness of the 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.
How to make a circular from a hand-held circular saw with your own hands. 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 your own hands. 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 disk. The connection is made using bolts, the clearance is adjusted with the supplied washers.
Install the strap clamp with the screw on 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 a bracket, a metal rod or pipe is taken as a basis. It is worth considering riveting, if the ends are relaxed, the handle may bend during mechanical action on it.
The advantages of homemade equipment
The main advantages of this technique include the following:
- Tool versatility.
- 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 thematic printed publications make it possible to manufacture equipment for processing both thin blanks and thick lumber. You can pick up the simplest options that do an excellent job of processing lining, thin lamellas and plywood.
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 keys 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 quickly stops.
Common causes of injury:
- 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 the workpieces with your hands from 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 an easy 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. It is especially important that all legs are the same length so that the product is stable.
Determining 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. The key property of the created table should be convenience.
Circular machine bed
You should take care of its stability. Any loosening is unacceptable, otherwise it will negatively affect safety. The countertop should have the most even surface. This will reduce the likelihood of injury during work.
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 that allows you to get rid of the chips flying into the working.
Circular table guide carriage
Some remove the factory cover and change the factory platform to 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.
How to make a shaft for a circular with your own hands.
If a circular saw with your own hands is assembled in parts, the engine is taken from the washing machine, the discs are bought separately or removed from a non-working angle grinder, then you will have to think about how to grind the shaft.
It is unsafe to make this important part from old pipes, since the disc itself will be attached to the shaft.
It is difficult to make a shaft for a circular saw with your own hands. Here you need a professional turner, preferably not a beginner. First you need to select a special 45 grade steel. The material is characterized by wear resistance and elasticity, specially designed for the manufacture of shafts, cylinders, gears.
For turning on a lathe, a double-sided mount is used. The part is first processed with a conventional cutter to give the desired diameter. Next, a finishing cutter removes all seizures. A small allowance is left for the final sanding with sandpaper to a mirror finish.
The grooves on the shaft are made with a grooving cutter, as indicated in the drawings. In the process of work, you can remove a part and try on components on it, which will subsequently be mounted.
The shaft can be fitted with fasteners for:
- Various cutters that can be useful when turning curly wood products;
- Regular circular;
- Planer knives.
A homemade circular saw with your own hands is equipped with a motor from an old washing machine. It is necessary to connect to it a starting device corresponding to the engine power.
When installing an electrician, you must follow the safety rules:
- Provide thermal protection for overvoltage cases.
- The electrical panel must be installed on a material that does not conduct current.
- If a metal frame is installed, then the wiring should be well insulated.
- If a homemade circular saw machine is on the street, then the electrical unit must be protected from water.
If it is difficult to conduct an electrician for a circular saw with your own hands, then it is better to turn to a professional so that the equipment works for a long time and without breakdowns.
Advantages and features of the tool
The circular saw has its advantages: it allows you to make an even cut, increases the speed of installation, provides ease of use, and saves electricity. If you replace the disc, you can overcome the soft metal. To make a complete tool for work, you need to place it on the table and provide an approach from all sides.
In this case, the following conditions must be observed:
- The table must be well strengthened, for which its legs are sometimes poured with concrete or screwed on with bolts;
- The hand saw is secured with iron brackets to the table top for safe working;
- Grounding required.
The large width of the table is inconvenient when working. The optimal size should not exceed 60. 70 cm, so that it is convenient to hold the bar (not on outstretched arms).
If the working surface is not static, then the quality of the cut deteriorates, therefore fixing is necessary. The wire can be secured with brackets in the floor to prevent accidental tripping during operation.
As an option. make an additional socket under the table top.
First you need to prepare a drawing of the table top with dimensions. This is almost a drawing, but simplified. On paper, you need to indicate the size of the gap for the disc. in width and length, where it should be in relation to the edges of the table. You can immediately imagine your work behind such a device.
Additional tools you will need:
- Screwdriver for fastenings;
- Electric drill;
- Pencil or marker for marking;
- Electric jigsaw;
In the process of work, you may need a router.
To make a table, you need to prepare:
- 2 guide rails;
- Chipboard sheet 60/120 cm;
- Blank for a table with legs (if any).
The bed can be made independently from ordinary wooden blanks, fastened together by slats, or a ready-made sawing table, iron or wooden, can be used.
For working with plexiglass, plastic, laminate, a mini-circular can be useful. a small design, similar to a stool with a disc in the center.
Such a model is designed for thin sheets of material and will not withstand heavy loads.
You can use an angle grinder by attaching it from below using the above method.
For an emphasis, you can attach a beam with a height of 2 cm.
The legs do not need to be reinforced because the device is planned to be moved.
The motor power on the microcircular is small. up to 40 W. The disc can be taken from a hand saw, but it is quite possible to use a prefabricated structure, where a threaded rod acts as a shaft. a construction hairpin. The disc is secured with a nut screwed onto the thread.
Description of the workflow
How the saw blade guide is made. A guide ruler attached to the workbench will help make the cut straight.
The essence of the device is to prevent the sawing material from moving during operation.
The easiest option is to attach two profiles, one on the base of the saw and the other on the saw table.
To do this, you need to pick up two pieces of pipe, you can use an aluminum square profile of different sizes. The pipes must be cut vertically with an angle grinder. You should get a structure similar to a rail, when one part enters another.
Next, you need to measure the piece along the length of the table. Pre-cut the recess and fit the profile into it, securing it with bolts from the bottom side. The smaller profile is cut to the length of the sole and bolted. The edges of the metal should be sanded so that they do not interfere with smooth movement. It remains to combine both profiles and test the device.
How to make a workbench
A table for a circular saw with your own hands can be made from MDF board, chipboard, thick plywood, wood, metal. Plastic material is not suitable.
- Measure the required length and width from a sheet of material.
- Cut off angle grinder and grind edges.
- Bolt the tabletop to the table legs, for fidelity, you can use wood glue.
- Level the top with a spirit level, fix it to the floor with metal brackets or pour concrete.
A circular saw from a circular saw is attached from the bottom to the table using wooden rails.
How to make a circular saw out of a circular saw with your own hands
A hand-held electric saw is a useful and convenient thing, but working with it will not work for a long time, since you need to make efforts. If you need to saw a whole tree or you constantly have to work with large volumes, then for this a circular is made from a circular saw with your own hands.
Description of work:
- Turn the tabletop over, mark with a marker and cut a hole for the disc.
- Cut the top layer according to the shape of the sole to a depth of 0.7 mm.
- Take two bars and fix the sole with self-tapping screws parallel to the length of the table.
- Fix the sole perpendicular to the table with two more slats.
The attachment of the circular saw to the workbench is now complete. If permanent work is planned, then you can equip the table with an additional emphasis. This requires a flat bar along the length of the table top. It is required to install it parallel to the saw blade, preferably in a recess, secure with bolts. It is important to align the part well so that it is located strictly parallel. the quality of the cut will depend on this, especially if you need to make furniture.
For the 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.
At the first stage of making a bed with a wooden tabletop with your own hands, the existing plywood sheet is placed in accordance with the existing sketch or drawing. In order to reduce the number of cuts, the marking is carried out from the edges of the sheet. A hacksaw with a fine tooth or a jigsaw is used as a tool.
On the underside of the sawn-off piece, a slot for the disc is marked. Cutting can be done with a finger mill, fixing it with your own hands in an electric drill chuck. In order to maintain the straightness of the cutting edges, a simple homemade 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 countertop along the entire joint plane.
The distance from the edge of the tabletop to the bar should be 2.0. 4.0 centimeters.
After that, in accordance with the selected drive design, the circular disk support assembly 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 tabletop 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.
Some of the nuances of manufacturing
The main parameter that determines the design of a self-made “circular” is the thickness of the boards being sawn. For DIY household work, it is usually not required to cut wood thicker than 15.0. 20.0 millimeters. To change the cutting depth, you can use and / or make a special mechanism for lifting the disc, but this will significantly complicate the design of the homemade product.
When choosing a drive motor, you should take into account the speed of its shaft. Using a belt drive, you can make a change in the number of revolutions yourself. 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.
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 desirable, but sometimes necessary. Unfortunately, the cost of an industrially manufactured sample of such a saw does not correspond to the frequency of its use at home, and for some Russians it is simply not affordable. At the same time, making a “circular” with your own hands is quite simple, using a sewing machine drive or an ordinary electric drill. However, the quality of work and the range of operations performed largely depend on the frame of the circular saw.
The simplest circular saw frame, the drive power of which does not exceed 0.8. 12 kilowatts, is quite affordable to make with your own hands from thick plywood and wooden blocks. 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 with a special bracket to under the plate. The length of the bed will depend on the length of the material being cut. For the table, you need to purchase bakelite plywood with a thickness of at least 50.0 millimeters. Of course, a wooden frame is not suitable for professional work, but in order to dissolve the boards, quickly saw through the bars, such a homemade construction is quite enough.
Despite the primitiveness of the described design, it will noticeably facilitate do-it-yourself homework, from carpentry operations with boards and ending with cross-cutting of thick knots cut from garden trees.
