How to Make a Saw At Home
and more confidently, hand-held electric tools replace our mechanical relatives in our home workshops. One of the first such replacements is the replacement of a hacksaw, a bow or two-handed electric circular saw. It is also often called circular (circular). In order not to get confused, we immediately make a reservation: circular. from the word compasses, which means. round, disk. The working tool in such saws is a disk: serrated, with various tooth configurations, with or without victorious soldering, with diamond coating for cutting ceramics and concrete, abrasive. for cutting metals and grinding, and sometimes felt. for grinding.
When choosing a wood saw, you should consider its versatility. But it is also important to keep in mind that some of its varieties are specific for use, and some other tools can successfully fulfill its role.
Stationary and table circular saws
Such machines will be useful to those who have a small workshop and quite often engaged in the manufacture of various molded wooden products: planed and grooved boards, lining. Sometimes such machines, in addition to a circular saw, also have a shaft for planing wood, which makes it possible to obtain products of sufficiently high processing purity at the output.
And to make such a machine with your own hands is not so difficult. Often the cost of this is less than the purchase of a factory-made hand-held circular saw.
But the functionality of the latter is in many cases higher. Optimum will be indicators of engine power of 1.5. 3 kW and a disk speed of 2. 4 thousand / rev.
Wood circular hand saw
Most often, this name means an instrument popularly called makita. by the name of the company that produces a large number of its varieties.
First of all, such a tool is most convenient for spreading sheets of OSB, fiberboard, chipboard, removing deep chamfers on molded wood material.
This is facilitated by a pad-stop pivotally mounted and able to move both in the plane of the circular saw, adjusting the cutting depth and in the perpendicular to it, at an angle of up to 45 °.
Most models of such a saw have a laser pointer of the cutting line, which allows tracking the direction of movement of the tool during cutting with sufficiently high accuracy. You can also do this by attaching a guide rail to the workpiece using clamps or self-tapping screws, along which one of the sides of the thrust pad will move. The tool has two handles that allow you to make the most accurate cut.
Power selection of circular saw
Power indicators of circulars are mainly in the range of 1200. 2500 W at revolutions of 4. 5 thousand. It all depends on what material you will process, but not even the most powerful specimens of saws can cope with a rather thick tree, but at a lower feed rate.
Choosing the diameter and bore of the disc
Some modifications of the circular saw have a case that allows turning it upside down with the disc, turning it into a kind of table circular, and the button that locks the power key ensures constant rotation of the disk.
Actually, any circular saw of this design can be easily converted into a stationary circular machine.
To do this, it is enough to choose a convenient stable bed (or make it) and a flat table cover, in which to make an appropriate slot for the disk and the place of attachment of the thrust saw blade. Sampling for it is not necessary, but it is desirable that, with great effort, the saw does not move into the groove. This can also be done by securing the support rails around the site. We fasten the saw with self-tapping screws or screws with caps in the pot, turn the table over and fasten it to the bed.
It remains to be said that the width of the slot for the disk should be sufficient so that the protection cover can move freely in it, and the power button is constantly locked by the button.

To cut the boards, it is convenient to have such a modification of the manual circular:
It is controlled with one hand, works with discs of smaller diameter and has less power. The minimum diameter of the disc is 150 mm, and the maximum is limited by the dimensions of the protective casing.
There are transitional models that combine both designs.
Such are held in high esteem by builders of frame houses, carpenters specializing in flooring, roofers. But for home and garden, in our opinion, this is one of the most successful solutions.
Small hand saws
First of all, they are intended for cutting curved shapes from sheet material. over, depending on the disks used, it can be not only wood, but also plastic, and even ceramics, flat stone and metal.
Although nothing prevents them from carrying out a long longitudinal cut.
The leader in sales among similar tools in recent years has become the so-called. rotorizer. Several Russian factories mastered its production, which made the price quite affordable.
And the abundance of types of circular saws installed on this tool makes it almost indispensable for the home master.
True, they still cannot carry out a large amount of work. there is not enough power, and the depth of cut is not very large. The outer diameter of the discs is only 50 mm, which contributes to the maneuverability of the tool, but limits the depth of cut. And the power of 400. 800 watts (individual models. up to 1 kW) does not make you wait for great performance.
A woman can easily work with such a tool, it is unpretentious and quite convenient, is controlled with one hand.
A separate type of circular saws is miter, otherwise called miter saws.
They allow high precision trimming of large quantities of material. And to do it including and at a given angle, which is ensured by the presence of a rotary table. Most of them allow you to install disks of rather large diameters, which increases the cleanliness of the cut. On the simplest models, the width and thickness of the workpiece to be machined depends on this parameter, but there are models equipped with guides that allow cutting of fairly wide workpieces.
Installers of wooden stairs love such models; they allow you to trim a wide step in one go.
The most universal miter saws also have a horizontal rotation of the working head.
Sometimes such saws are equipped with additional retractable stops, which allow more accurately positioning the workpiece, and even with additional roller tables for working with heavy and long beams.
But it is rather a professional tool. Although it’s not so difficult to make it look like home. Most often, a manual electric tool such as an angle grinder, popularly referred to as an angle grinder, is used for this purpose. It can also be considered as a home circular saw, especially with minor modifications.
Circular Saw from Angle Grinder and Drill
There are industrial designs of machines for an angle grinder, turning it into a miter saw not only for wood, but also for metal.
And to make such a device yourself is not at all difficult if you possess the skills of a welder.
Although the same design can be made of wood.
It is even easier to make a stationary circular saw from an angle grinder. To do this, it is enough to securely fix it on the bed, and remove the disk through the slot in the desktop.
The biggest disadvantage of this design is its low security in terms of safety, which, however, does not affect performance. It remains to add that for such purposes it is better to choose an angle grinder with adjustable speed.
An electric drill can also act as a wood saw. To do this, you will need to grind the adapter for mounting the working tool itself and securely fix it on the bed.
For manual modifications of circular saws on wood, there are special nozzles for drills.
Simpler. direct action:
And more complicated. with angular transmission:
The first is in our household, so we can say that with its help it is possible to perform more than 90% of all types of work for which the most common hand-held circular saw, called makita, is intended.
Our choice of circular saw
If we are talking about the most versatile tool for a wide range of types of work in the country or in a home workshop, then we would recommend choosing a medium-power saw (approx. 1.6 kW) with revolutions of at least 4 thousand and a saw blade diameter of 200. 230 mm From domestic, Interskol proved to be very good. When choosing a tool of Chinese manufacturers, keep in mind that the real power will be 30. 40% lower than declared due to the difference in measurement methods.
