How to work with a circular saw correctly
Start with a good drive
For clean cross-cutting of bulky wood, decorative plywood and other sheet and panel materials, swap the standard 24-tooth blade, which most models are equipped with, with a 50-60-tooth blade.
And for most cuts where quality requirements are not very high, use a 40-tooth blade. How to work with therefore use the circular saw before starting to saw. And only for ripping bulky wood species, reinstall the standard 24-tooth blade.
Get rid of chips in one of three ways
The teeth of the saw blade rotate forward and upward. The underside of the workpiece, where the teeth enter the material, almost always remains clean, without chips. On the contrary, the top side usually happens to be so chipped that it cannot be used in visible places of the product (compare three photos with different degrees of chipping).
How to work with a hand saw before starting to saw with a circular saw is as follows. Therefore, if possible, always lay the sheet or strip face down for cutting. And if you have to cut to the right side, use one of these techniques to keep the cut edges clear.
1. Preparatory pruning
Cut two times instead of one. The 1st shallow cut will cleanly cut surface wood fibers so that they will not be pulled up in the final cut.

2.Use an anti-splinter pad
Attach a hardboard plate to the base of the circular saw to clamp down on the surface wood fibers, especially on materials covered with firewood veneer, and to prevent chipping where the teeth of the blade come out of the material.
By choosing a board with a circular saw, dissolve a board how to make it out of boards. Smoothly plunging into the rotating blade and sawing through it, you get an anti-splinter pad, the width of the shed in which will exactly match the thickness of the saw blade. It will help minimize chipping.
Attention! Be extremely careful when working with such a pad, as it prevents the protective cover from covering the disc from below.
3. Make a guide bar
This guide bar will not only help to deal with chipping, but it also simplifies the cutting work, so you don’t have to resort to calculations. Make it as shown in the picture.

The distance between the edge of the base and the stop should be 10-12 mm more than the distance from the saw blade to the edge of the sole of your saw.
File the edge of the guide bar by pressing the sole against the stop. For sawing with a circular hand saw how to use; how about the repair. Now one edge of such a tire will act as a splinter pad, pressing the fibers from above. Before cutting, put the tire on top of the future part, since chips will appear on the other edge of the cut, where the fibers are not pressed.
The nozzle for removing bark from logs is used due to the wedge transmission. Attachment takes place with belts – special pulleys are used for this.
Cutting the board at home
You can cut a board at home with tools and equipment such as:
- A circular saw;
- Hand saw;
- Angle grinder ("angle grinder").
Each of these options has its own specifics, which is important to consider before starting work, that is, you need to know how to cut a bar or board with this or that tool so that the cut quality is acceptable.
Preparing to assemble the table
Table assembly diagram.
The simplest version of a circular table is a structure made of fairly thick plywood and boards. Plywood in this case will be used for the manufacture of countertops. The countertop itself will be stationary. The tool must be installed under it. Previously, a slot is created in the cover along which the saw blade will move.
Choose the size of the table, first of all, with a focus on yourself. You should be comfortable and comfortable working. The instructions cover the average and most common sizes. You can change them at your discretion. The height of the table is 1-1.15 m. Choose the length taking into account the nature of future work. If you are cutting long boards most of the time, make the table top long enough as well. If the length of the table top is more than 2 m, it is recommended to equip the structure with an additional pair of support legs. Without them, the table will vibrate a lot.
The thickness of the plywood used for the manufacture of the countertop should be from 5 cm. Plexiglas, fiberglass are suitable for the same purpose. Masters recommend refraining from using chipboard due to the insufficiently high strength of the material.
The cover is polished and varnished in several layers. This will ensure the required sliding of the processed materials. The best option is to attach a metal sheet to the countertop. This will increase the reliability of the surface and extend the life of the product as a whole.
Step-by-step instructions for assembling the table

First you need to shape the countertop. Take a sheet of plywood and mark up. The edges of the sheet should line up with the two edges of the cover. Saw out the workpiece with a hacksaw or jigsaw. Cut the cuts with a cutter if desired. This is optional, so you can skip this step. In the case of a circular saw table, reliability is more important than good looks. Rough the countertop with sandpaper.
Prepare a disc slot at the bottom. Measure the foot of the circular saw. For maximum convenience, remove the saw blade from the tool and simply circle the desired part of the saw.
Next, you need to take a hand cutter and select a material about 8-10 mm. If there is no cutter, use a chisel. The result will be the same, but it will take more time and effort.
After completing the arrangement of the seat, try on the plate and make the required adjustments. Mark the slots for the saw blade and fasteners. If the disc is to rise and fall, the table must be equipped with a pendulum mechanism. In this case, the shape of the slot should look like a truncated pyramid. The top of this peculiar pyramid must be directed downward. For the manufacture of the frame of the lifting mechanism, it is better to use metal corners welded to each other.
Circular saw table design
Before assembling a circular table with your own hands, you need to carefully consider its design. At this stage, your task is reduced, first of all, to calculating the load that will be placed on the table in the future. When assembling a saw table with your own hands, take into account the power of the unit. So, for high power industrial tools, it is recommended to use a reinforced steel welded structure. In the case of a house saw, there is no need for such a powerful design. It will be enough to assemble a saw table with your own hands from boards and plywood.
Circular table device.
When planning to make a table for a saw with your own hands, you need, as already noted, to take into account the power of the tool. In home workshops, saws with a power of up to 800 W are most often used. At the same time, it is necessary to take into account the frequency and volume of work performed. For example, when building a house, you will have to cut much more material than under any other conditions. Experts do not advise buying saws more powerful than 1200 watts for the home. In the case of a home workshop, this simply does not make sense.
The higher the power of the circular saw and the higher the volume of work performed, the more reliable, durable and stable the table you create should be. Professional grade circular saws are installed on metal profile bases. In some cases, such tables are even embedded in the floor, since vibration can cause the operator to briefly lose control of the saw, which will be enough to cause injury. The creation of such a table requires certain skills in working with special tools, welding, etc. Assembling an ordinary wooden table for a house saw is available to almost everyone, even if he does not have such experience.
Hand-held circular saw – getting to know the fixture
This device came about thanks to Tabitha Babbitt, who realized that sawing with a conventional saw is only effective in one direction, so she came up with the idea of a circular blade rotating in one direction. And such thoughts crept into her while observing the men, how they, strong and healthy, waste 50% of their strength, moving the saw blade back and forth, and the work stands and waits. All this happened as much as 200 years ago, but today the hand-held circular saw for wood has undergone many modifications and "overgrown" with various devices for the convenience of work.
This tool looks like a sharp-toothed disc that can be installed on any more or less powerful unit that has a torque. But due to the popularity of using this idea in repair and construction, an autonomous machine is now being produced, which serves only for sawing, and in addition to the disk, it has all kinds of convenience for work, for example, clamps and stops. Such a circular saw with a guide keeps the correct path, you can even cut at an angle. There is also a device for collecting and ejecting sawdust, which will certainly form under the disc, but do not always fall down, but fly up, clogging up the important "organs" of the instrument.
The modern market is full of models of this device for the household. A stationary circular saw will look good in your workshop if you often cut lumber. And if you are doing work all the time at various points of your site, or even driving around objects, then a mobile copy, which is small in size, will completely satisfy your needs. A small circular saw can even be the result of your skillful hands, there are many instructions on how to make one yourself.
Electric circular saw – we select discs for the tool
But making an effective tool yourself is quite difficult, so let’s define the characteristics and find out which circular saw is better. From the point of view of geometry, these devices can differ in the shape and method of sharpening the teeth, this affects the smoothness of the cut and the accuracy of the edge. There are flat teeth (very rough work is obtained), trapezoidal (they can cut thinly and accurately), variable (they take wood well along the fibers) and others. Also, this parameter can affect the ability to cut certain materials, for example, a circular saw for metal often has trapezoidal teeth.
Of the characteristics of the disc itself, the outer diameter, the number of teeth, and the thickness of the blade are important. For miniature models, a very small disc diameter is used – 15 cm, the cutting depth, of course, will be small, which means that only simple work can be performed. The most popular large discs are considered to be options with a diameter of up to 20 cm. In general, when buying a tool, you need to choose this larger parameter so that other sizes of discs, which are slightly smaller, can be put into the slot. You cannot put a large disc in a small slot, it will cut the protective covers.
But the inner diameter of the disc is important to know for sure, this is the landing size. Having chosen it incorrectly, you will not be able to fix the disk in the instrument, although there are now adapter rings, but this is not a very convenient option. The number of teeth affects the pace and quality of work. If we take a disc with a low concentration of teeth (for example, 24 teeth for a diameter of 20 cm), then the cut will be rough, but the work is fast. If you are ready to spend a little more time on work and would like to see a neat cut, then the number of teeth should be taken more. It is good to have a set of discs so that you can take a more convenient one for each occasion.
Hand-held circular saw – for real men!
The hand-held circular saw is an excellent alternative to the familiar hacksaw, which is very handy for sawing boards from side to side, but along is sheer flour. But the circular will make this lesson very fast, and the result will be much better.
