When buying a circular saw, the future master does not always imagine the amount of work that he will have to perform with this equipment. This is one side of the problem. On the other hand, the master understands that it is better for him to purchase a circular machine at once, but it is very difficult to find a convenient table that would meet all the requirements.
The circular table allows you to make a more accurate and even cut.
Thus, the idea is born to make a table for a hand-held circular saw with your own hands. In this area, these craftsmen have no restrictions.
General Requirements for a Circular Saw Table

The work saw table must meet several basic requirements:
- support stiffness;
In addition to these requirements, there are several necessary conditions that must be considered when creating the machine for a circular saw.
- Safety and reliability of fixing the saw.
- Fencing for saw blade, which very often remains unfulfilled.
- Free access to on / off button.
The additional set of features of devices depends on the requirements of the master himself and his qualifications. This kit includes accessories that:
- help to carry out an equal longitudinal cut;
- the same high-quality cross cut.
Circular saw design.
The standard table, which can be purchased with a circular saw, is usually made of stainless steel. The sawing device itself is fastened upside down, a cut or a slit is made approximately in the middle to place the disk of the saw itself in it. Its width should correspond to the width used saw blades. We must not allow this gap to be too wide. In this case, chips and other working debris will often clog the device, disabling it.
As for the technical parameters of the saw, which will be used for machine sawing, the power of its engine may be greater than that of a conventional hand saw. But still do not exceed 1200 W, experts believe such a risk is unjustified. After all, the more powerful the saw, the more durable and reliable the table is needed.
Industrial machines are made, as already mentioned, exclusively from metal, but their support is often poured with cement for more reliable fixing of the device.Back to table of contents
Required material and table assembly for a hand-held circular saw
Cutting with a circular saw.
For the manufacture of the table, you can take the following materials:
- plywood 20-50 mm thick;
- fiberglass plates.
When choosing a saw in the store, the buyer often pays attention to the depth of immersion of this device, which means the maximum thickness of the material being processed. It must be assumed that the use of a hand saw for the wrong purpose will take about 1 cm of sawing thickness.
Table parameters are largely dependent on the surfaces to be treated.
Check circular saw.
If it is assumed that the products will be bulky, for example, with a length of more than 2.5 m, then the table will have to be strengthened with additional legs.
The circular table has several features in its assembly. The blank for the table cover should be described as a separate item.
So, for the table top legs are made of the same plywood, but of greater thickness. For its fixing do clamps along the table or crosswise. This will allow the table to be more rigid. The correct length of the legs and the place of installation will affect the stability.
The table can have various sizes, the master determines these parameters independently. For example:
- cover 70x80 cm;
- height 110 cm
Table cover: how much can be useful on it
The scheme of use of a circular saw.
For the saw itself, depending on the selected thickness of the table top, a cut is made about 1 cm deep. Cut is made to fasten the desktop of the device itself around the perimeter. In order to make it, using a ruler, a simple pencil and the handsaw itself, mark the place where the device will be located.
There are several options like attaching the saw to the table. It all depends on what goal is set. If a person wants the saw to be freely dismantled if necessary, the mount should allow it to be done, but at the same time be reliable.
To do this, around the marked perimeter of the working surface of the saw, set the bounding bars with grooves, not forming a closed frame. Thus fixed hand saw. But such an installation is applicable for small amounts of work and low speed discs.
A more reliable fastening looks the same, but with such an attachment, the bars have a smaller size: there are not 4, but 6 or 8, each is fixed near a particular section of the bed, and if necessary, the master will have to unscrew the bolts near each such bar. Some attach a circular saw without wooden bars, screwing it directly to the table, making holes in the frame.
Turning the lid over the table, you can see the slot with a saw blade protruding from it. When installing, the disk platform lock function is used.
You can make a slot on the sawing table for a removable rasklinovochnogo knife, which with the help of a clamp will be attached next to the saw from the bottom.Back to table of contents
Guides for longitudinal and transverse cuts
The table should have guides, for their manufacture use aluminum U-shaped rails. With an open edge, they cling to the table. Subsequently, the auxiliary fastener parts will be moved along them, allowing for more accurate cuts.
The first must be built guide along the saw. Reiki for parallel guide will go along the edges of the table, perpendicular to the saw itself. The guides themselves are also made of plywood.Back to table of contents
How to perform cross cuts?
Barrel for circular saw.
To perform cross cuts most often use a bar that looks like a small table. It is turned upside down, has 2 parallel bases and a slot through which the saw disk can pass. If all corners were observed, the cut will be strictly perpendicular.
The crosscutting solution can be another interesting option. On the plywood (slightly larger than the table) are fixed bars from the bottom side. They should be located clearly on the width of the table. From the top of the board are mounted 2 parallel plates that are above the saw blade and have slots for its passage. The result is the same, but this solution is easier to implement.
In addition, the table cover can be equipped with rulers on both guides.Back to table of contents
Some useful things you need to know.
The inclusion of a circular hand saw can be accomplished in several ways.
The easiest and wrong: fixing the power on lock button, connect directly to the network, disconnect if necessary. So do contraindicated for 2 reasons:
- unsafe for life and health of the master;
- threatens the saw engine with combustion.
The second method is perhaps the most common. Everything is fixed, but the saw does not turn on the network, but in an adapter with an off button.
The third way is the most correct, but it can deprive the owner of the device of a guarantee for it. It is necessary to bring on the desk panel a plastic blank for the on and off buttons. Replace the wire with the plug on the wire that will be directly connected to these buttons. Safe for both master and saw.
Assembling the front of the machine.
In fact, it is not at all necessary that the saw be fastened at the bottom of the table. Many ways are invented when, by means of additional devices, a circular can move on top. So, if on the one hand the sole of the circular saw is equipped with a special platform, by making a tire out of aluminum rectangular pipe about 1 cm in advance and securing it to the surface being sawn strictly parallel to the shear, you can make an exact cut. This becomes possible due to the fact that the saw with the help of the platform moves along the tire without changing the distance to the edge of the cut.
There is a variety of circular immersion saws. They have a controlled device that holds the saw over the product, if necessary, drop.
We must not forget that you can buy a stationary table with a saw.
In this section, I would like to say a few words about the saw blades themselves. They are:
- for longitudinal sawing;
- for cross-cutting;
The first 2 kinds of discs differ in the sharpening method. For working with a cross section, a so-called negative angle of sharpening is used.
When the master does not know what exactly he will be sawing, or the product range requires cutting in different directions, it is recommended to use universal discs. This will prevent the need for changing saw blades frequently. The teeth of such discs are made of excellent material.
It is necessary to carefully read the instructions for working with the saw.
It is important that the table is set smoothly, it is necessary for safety and to avoid production defects. Some countertops are treated with a grinder and varnished, it can be covered with a thin layer of metal. But we must not forget that each extra layer gives a minus for the maximum cutting depth.
