Homemade circular saw machine
Most carpenters and woodworkers, wish to have a universal unit in the household, but how to make such a device on their own, many do not know. In this guide, you will learn how to make a universal milling table with their own hands. The advantage of a universal woodworking machine is that there is no need to have several units and walk with the workpiece from one to another while working. The only and universal, will be on one table, and perform the actions of several units. Of course, the limitations of such a device are present, and to make an absolutely-universal machine for wood is not possible. But to make a table for the cutter with his hands, which will be present electric planer and circular saw, it is quite realistic. To translate the idea into reality, you need to take care of consumables, as well as tools that will be needed to create an accurate and level table on which the devices will be fixed. Since there will be more than one device on the table, you need to make a wider and longer table. In order not to spoil materials in vain, you should first draw a scheme and location of future devices on a piece of paper. This is an extremely significant argument, since the efficiency of the machine directly depends on the competent arrangement of all elements. Take care in advance about the position of each node. If the task seems very complicated, you can use ready-made diagrams and drawings. Thus, craftsmen make a table for a circular saw with their own hands, without the help of experts.
The structure on which the woodworking mechanisms will be installed must have these characteristics:
- Capital stiffness and stability.
- A perfectly level surface.
- Free space for sawdust.
- Easy accessibility to waste for disposal.
- Protective shields that are mounted over the rotating elements.
How To Make A Homemade Table Saw With Circular Saw
Compliance with the above rules, will help to make a really high-quality and safe table for the cutter with their own hands.
There are several circular saw requirements that must be considered for quality, productive, and safe operation of the unit.
A good saw blade mount. 2. Fencing the working part of the saw blade, which many people consider an impossible task. 3. Availability of a start-stop button for the machine.
Additional requirements for the table, depend on the preferences of the carpenter and his professionalism in this area. Auxiliary elements will help to process blanks more precisely, to make sawing of longer boards that will finally reflect on the possibilities of the machine to make absolutely accurate, high-quality and complex products.
Most craftsmen, perform drawings of the milling table with their own hands, and if there is no confidence, it is better to work with a locksmith, or a person who has made a similar device.
The device of the working table
The design of the table for a manual circular saw is so elementary that most specialists make it without preparatory drawings and techniques. This is a dense workbench, which is created from wood and plywood.
The strongest table bases are made of alloy. They are the heaviest and require the presence of skills of a welder. Therefore, stands are often made of leftover lumber. The circular saw is fastened under the table top and the storage unit protrudes over it through a specially made slit. Sawn timber is pushed along the table top and sawn with the disc. For convenience and correctness of work, the table is equipped with additional devices: an angular and longitudinal stop.
Tabletop “absorbs” a part of the working plane of the disk, the depth of cut will be reduced by the thickness of the tabletop. For this reason it is preferable to choose a circular saw with the largest blade diameter and a thin but rigid table top.
If you have not yet purchased an electric saw, choose modifications with high power (from 1200 watts). They can handle large wood cuts. Holes will be drilled in the base to secure it. The solid base might break. For this reason it is advisable to choose another type of mechanism.
A manual circular saw can be used for this purpose quite normally. Power and diameter of the disc directly depends on what and how much you are going to work. Remember also that clamping to the table steals up to 20 mm of the maximum cutting depth so that single handed saws with 120 mm blade are not suitable for this application. Having a circular saw with adjustable depth and angle of cut will give you more options for fine machining parts and cutting drawer grooves.

Saw blade plate size 350x250mm made of two sheets of metal, ready to install (assembled).
Reliable attachment of the saw sole to the plate is carried out in five points and does not require drilling of the saw sole (excludes problems with warranty period), as well as additional repeated adjustments and checks during each work performance. Also does not cause additional stresses and deformations in the plate itself.
How to choose a plate for felling and milling tables: see here!
The saw blade fastening system on the plate allows to keep the saw blade tilted on 90-45 degrees and allows to set the saw blade parallel to the edge of the plate once and to base the sole of the saw exactly on the place with saving of previous settings during re-setting.
The combination of two sheets of metal forms a landing place for the antislip plates, which are cut from textolite or plastic themselves. The metal template is included with the plate, which can serve as a plug, and by which you can cut the antislip plates for a straight cut (90 degrees) or oblique (45 and 60 degrees).
I don’t make metal backlash plates, because of the requirement that the circular saw blade. safety, t.к. if the saw blade accidentally bumps into the metal plate the metal plate will be irretrievably damaged.
Setting up the circular saw before working
Before you start sawing you set up the circular saw blade and make sure it is firmly in place. The cover should open and return to its original position without resistance. It is also worth checking that the riving knife is correctly positioned. Then run the saw for 10 seconds at idle to make sure it is in good working order.
To adjust the circular saw, you need to adjust the required position of the guide pin and the cutting disc with a caliper. When checking the position of teeth in the front and back of the disk difference should not be more than 0.05 mm. Also you need to install the riving knife and blade so that they were in line with each other. For their fine tuning special washers are used. To make the tool and the table less vibrating, you need to tighten the fastening bolts well.
Sawing table with my own hands from a handheld circular saw
Makeshift sawing table with his own hands, photos and detailed description is attached.
Here I have decided to make a cheap and practical sawing table from a handmade circular saw. I bought laminated chipboard (yes, it is not right to do such things from chipboard, but, realistically, I have not found moisture-resistant plywood, and admittedly in Minsk, I have never seen it in the eyes). Took two pieces of 600 x 800 x 16 mm and 300 x 800 x 16 mm. Bought an aluminum angle 20 x 40 x 2000 mm and channel 10 x 10 x 2000 mm. Got 40 screws, two 500 mm metal rulers.
Got to work. The base will be a 600mm x 800mm slab. Plate 300 x 800 mm, I cut it into 50 x 800 mm slats. With them I made a trimwhich added rigidity. Assembled everything with Kleiberit PUR 501.
Milled a hollow for the channel and glued it with Soudal Fix All Classic. Too bad the channel is a 10not a 15but what do I haveI’ll find it, maybe I’ll redo it. Next, I milled the tracks to fit the ruler.
Rulers cut to size, precisely positioned on the disk, and glued them with Soudal.
Then I made parallel stop. Once again I had no desire to squeeze the piece of wood every time with clamps, so I decided to use the factory sawing machines. The basis of the aluminum angle 20 x 40 mm. Its stiffness is not special, so I reinforced it with a wooden plank, gluing them all together. riveted a 20 x 20 mm corner to the back of the rail. This already allows the stop to be positioned perpendicular to the table. I decided to make a fuss with the fastener. To realize the idea, I needed a piece of aluminum.
Where to get a piece of aluminum? Sawing off from the disk.
I took the clamp I didn’t need I borrowed the parts I needed from it.
I married the parallel stop to the clamp with two bolts with anaerobic glue.
It turned out very convenient not much worse than factory quickrelease chocks Then the next little thing installation of power sockets, wiring, the switch. The button in the saw is fixed.
All this works in conjunction with a vacuum cleaner with an autopower. I forgot to take a picture of the broach carriagebut it’s pretty clear. Circular saw is now standing on the basis of the 160th disk this is certainly not enough. At this point the thickness of the kerf is 37mm.
I’ll probably buy and install another circular saw in a monthbased on a 210 or 235 disc. It will have to be a circular saw with a riving knife. If I will put a circular saw with 210-235 blades, then I will build the soft starter module for the saw.
Of course, such a sawing table from a manual circular saw is an economy optionneed makes. And it does not fully replace the factory productespecially when it comes to sawing at angles. My table has two positions90 and 45 degrees. As a rule, this is enough. Excluding the circular saw, which was in the householdthe cost of all materials (without glue) was 30even with a 235d disk saw, the cost of such a machine would not exceed 160which is exactly half the price, a factory table like Bosch or Makita.
The making process: step by step instructions
The tabletop under the circular saw in the finished form
To make a quality construction it is necessary to follow some tips. The process consists of several steps, as shown in the table.
|1||The bar on all sides should be trimmed with a planer. Then the frame of the future table is assembled from it. Drill several 5 mm holes in each side of the countertop. Additionally one through hole is made for the legs of the product.|
|2||Several holes of similar diameter are made in each leg. In the legs perform one through hole. Diameter remains the same, 5 mm.|
|3||Proceed with the installation of dowels into the countertop. Before this they are coated with carpentry glue. Put the legs and feet on top. If you have clamps with scissors, use them to fix the product. When the glue is completely dry, you need to fasten the reigns and legs, using special fasteners made of metal. Additionally, you should tighten with self-tapping screws. To add strength and sturdiness to the structure, you can use corners. They will be an element of additional fastening, will give stability to the product. For the short side 2 are enough, and for the long side 3 will do.|
|4||The next step involves securing the saw to the product on the inside. There are several methods to accomplish this task. M4 bolts or bars with self-tapping screws are good for fixing. The first case is fast and reliable. The second method does not involve additional holes, which eliminates the need for drilling. It is necessary to make a cut in the bars, the width of which is equal to the dimensions of the saw’s platform. Then self-tapping screws and timbers on both sides fasten the equipment and the table top|
|5||After installation of the saw you will need another bar of a larger size. It is fastened to the base with self-tapping screws. Screwing is done on the marks made when aligning the platform in a level position. The above manipulation will help, when removing the saw, to return it usually quickly without looking for the marks|
|6||The saw blade is installed in its proper place. The base is sawn through to obtain a longitudinal hole. Then turn the product upside down|
|7||Then start making the parallel stop. Two bars are sawn off from the plywood. Their length must coincide with the width of the table. On average, these dimensions are 10 cm. The corners should be rounded|
|8||The resulting strips are being sanded. They must be fastened at an angle with self-tapping screws. A metal angle must be screwed inside|
|9||If it is necessary to fix a stop on the base and the structure will be used frequently, a guide must be attached so that it is perpendicular to the blade. Attach the roller to the bottom. This will allow it to move.|
The set-up is completed and ready for use. When carrying out the described manipulations it is important to remember about the observance of safety measures. This also applies to any manipulation with the circular saw.
Check regularly the position of the table and its firmness. The construction should be stable, without loosening.

First make sure the saw is securely fastened, only then start the saw. Do not hold the material you are cutting with your hands. This will help avoid getting wood in the face when the knots start to bounce off. It is additionally recommended to use special protective glasses at work.
For safety wear safety goggles are essential
These simple tips will help you avoid injuries in the workplace.

No woodwork is complete without sawing. A manual circular saw isn’t very handy for my tasks, and I’ve had the urge to make a table for a circular saw for a long time. Т.к. I have a small workshop. I also needed a small table. Last week I finally made it. (“Lazy. Engine of progress” It was necessary to saw for the next wooden product, and I did not even want to start without it) It took 4 evenings to make a table with accessories.
The table is simple but very functional.Table dimensions (W520 x D500 x H230 mm), crosscut sled (W580 x D170 x H80 mm)
Stop for longitudinal sawing.
For the table top I found a sheet of 9mm laminated plywood at the market. What was very pleased it was perfectly sawed: all sides are strictly 90 o. I attached the hand-held circular saw BlackDecker CD601 to the table top. (1100W, 5000rpm, 170mm). The saw can change the depth and angle of cut.
After aligning the saw perfectly to one of the edges of the table I fastened it with M4 screws. For that I had to drill the iron base of the circular saw in four places.
Any circular saw will generally fit on the table, but if you choose the type of attachment with screws to the base. then it is better to choose a model with an iron base. The cast can crack.
There is another popular way to attach the circular saw to the table without drilling holes in the base. Attach it with clamps, which fix the base, pressing it to the surface. Only it seemed to me that this method is not correct enough in terms of accuracy and reliability of installation, and I did not use it.
Another important parameter of the manual circular saw. is the ability to connect a vacuum cleaner. When sawing without a vacuum cleaner. small wood dust goes up in the air.
I made the base out of 22mm chipboard. I chose the size of base so, that it would be possible to attach the accessories to the edge of the table top.
The blade is sawed through to the top side of the table top. Height. 40mm (Bosh 160mm wood disk). The worktop reduces the cutting depth by 9 mm. Depth of cut is set on the circular saw itself. It is convenient, that the disk can be completely hidden in the table.
UPD: IMPORTANT! On some budget circular saws it may be that the blade is in an imperceptible inclination. And all cuts will be beveled. It is obligatory to check with tool angle that the disk is under 90 deg relative to the table surface. (It is possible to check the angle in relation to the native plate before mounting the saw). If the disk was not at a right angle and there is no opportunity to set the perfect angle. You can put a few strips of tin under one side of the pad, achieving the ideal angle (you can put washers under the screws that fasten the saw to the table, but this solution is worse)
To make the start of the saw more manageable. put a start button (turned out to be a. the most expensive part of my table 🙂 )
Inside the table I placed a socket for the saw, which will now be turned on by the start button.
For that the button of the saw on the handle was fixed with a coupler in the pressed position.
Here’s how you can connect a vacuum cleaner to the saw. In general, the table is ready and you can saw. (made in one evening and one morning).
