The woodworking industry cannot do without a high-performance sawmill. This tool has not only excellent speed and performance, but also the desired quality. But despite the fact that this is the most successful solution that exists today for processing a large number of workpieces, not everyone can buy such a tool. A circular sawmill can be made with your own hands. It will take time, desire, some skills and a tool.

About product design

Before you decide to make a homemade tool, it will not be superfluous to figure out its design. By and large, this is a machine that performs longitudinal sawing of wood, and it always works from an electric motor.

On the desktop is a disk on the shaft. It is natural that above the working plane rotatescutting edge of the disk. In principle, this is the simplest design that is best suited for home use. We can say that for domestic use it does not make sense to implement a more complex scheme.

The circular saw can be mounted both on the spindle shaft and on the motor shaft. The carriage can be assembled from various parts, but the rollers must fit well under the rail, which will be used as the main guide. If the rails have visible defects, in the form of bumps, chips, etc., then the carriage may wedge during operation, which is not good.

Disk sawmill: the price of finished equipment and home-made

As noted a little above, it makes no sense to purchase an industrial tool for domestic needs. Moreover, sometimes there is simply no money for it. Naturally, a sawmill bought in a store, even if not the largest and most powerful, will cost much more than a home-made one. Of course, in the first case, you will receive a guarantee and a better and more reliable tool. But if you make due efforts, then you can make exactly the same sawmill yourself. Although the guarantee for it, of course, will not be. So, the price of the simplest sawmills, which are sold today, starts from 25-30 thousand rubles. The most expensive options will cost hundreds of thousands. At the same time, the price of home-made can be minimal - 10,000 rubles or even less. Most of the parts, for example, fasteners, carriage, guides and the engine, can be found at home, and what is missing can be purchased. Agree that a circular sawmill, the price ofwhich is much less, and the quality is at the level, attracts much more.

About instrument classification

The sawmill can cut almost all roundwood materials. For example, edged and unedged boards, bars, beams, and so on. Usually the diameter of a circular saw is 50-60 cm, but if the tool is intended for domestic purposes, it may be less. As noted above, it is fixed on the spindle shaft with the possibility of cutting in two directions and turning the saw 90 degrees. This fact indicates that there are several types of sawmills depending on the type of work:

• Horizontal - the most common in this industry. Its design allows for easy assembly and transportation, and leaves little to no waste.
• Angular sawmill - uses the angle sawing principle. The design provides for 1 or 2 saws. Saw blades are fed orthogonally.

Horizontal sawmill

When working with a “standard” sawmill, that is, a horizontal one, there is no idling at all. In principle, this is its main significant advantage, which cannot be ignored. Sawing blanks is carried out using a carriage that runs along the processed material along the guides. If you decide to make such a sawmill with your own hands, then it is better to purchase a disk with a diameter of at least 55 cm. As for the teeth, the mainrequirements for them are wear resistance and strength. In priority, the teeth should be made from Pobedite. This will ensure not only an accurate cut, but also the absence of defects, for example, undulating depressions.

Charcoal sawmills

This kind of tool can have both one working body and two. In the first case, the sawing of blanks is carried out in the vertical and horizontal directions. It is also interesting that in this case there is no idling, as in a horizontal sawmill. In double-disk equipment, wood is fed orthogonally. Two working disks have a horizontal and vertical arrangement relative to each other. This ensures high performance of such equipment. Although it makes sense to say that the price of corner double-disk sawmills is quite high. Not everyone can afford it, and there is no point in buying such an instrument for an amateur. So let's talk about how to make a sawmill yourself. This is not as difficult to do as it might seem at first glance.

Making a sawmill: part 1

If you still decide to make woodworking equipment with your own hands, then you will need a tool. Firstly, purchase fasteners (bolts, nuts, etc.), and secondly, construction goats will come in handy, which will continue to perform an important function. The main element is the electric motor. There are no special restrictions here. The main thing is that the power of the motor is not too small. For example, an electric motor fromchainsaws. As noted above, the circular saw is the main working body of the sawmill. It can be mounted on the shaft of a spindle or an electric motor. If you do not need too much performance and accuracy, you can use the most elementary circuit. Its essence lies in the fact that there is a table under which the saw is mounted on the shaft. The cutting part of the disk should be slightly higher than the table. To transmit torque, it is best to use a belt drive, as in this case it will provide the best performance.

Making a sawmill: part 2

As a table or bed, that is, the main equipment, you can use metal or wooden goats. For example, a do-it-yourself circular sawmill can be made using several wooden goats, which will be connected to each other by small pieces of boards. On top of this design, a prefabricated table of metal plates 200 mm wide and 4 mm thick is installed. Between themselves, the plates can be connected with jumpers or screws.

Steel or duralumin sheet can be used as a blank for the future disc. Usually the thickness of a circular saw should not exceed 3 mm, and the diameter, as noted above, is not recommended to be taken less than 500 mm. It is interesting that the angular disc sawmill can have only a few teeth. At the same time, the efficiency of its work will be at a sufficient level. Do not forget that the angle of inclination of the teeth should not be less than 30 degrees.

A few more interesting moments

It is extremely important to securely fasten the cutting tool. The disk should be clearly in the middle of a pre-prepared gap. A mini-sawmill (disk) must have a high-quality guide. To do this, you can use the design of the U-shaped saddle. Formation of the product must be strictly according to the shape of the log. For manufacturing, you can use ordinary boards. It is desirable to pre-clear them of knots and process them with a planer. Already to the finished saddle, you need to mount the electric motor and saw. By the way, it is undesirable to install a motor whose power will be less than 1.2 kW, however, it is also not necessary to exceed 2 kW. At the final stage, the table is screwed to the frame. This is for screws. In principle, on this, all assembly and installation work can be considered completed.

Conclusion

If all the above requirements and conditions are taken into account when working, then you will be surprised at the quality of the manufactured equipment. In principle, the home-made sawmill reviews are positive. Partly because it is unlikely that someone will write badly about their product. Plus, it's a great way to save a ton of money. You will gain precious experience and will be able to process almost any type of wood. Do not forget to control the execution of work at all stages. Since you are dealing with a high-speed tool, be careful and follow basic safety rules. In principle, this is all that can be said about how to makedo-it-yourself sawmill.
