In the woodworking industry, you can not 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 is available today for processing a large number of workpieces, not everyone can buy such a tool. Disk sawmill can be made with your own hands. This 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 understand 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. Naturally, the cutting part of the disc rotates above the working plane. In principle, this is the simplest design that is best suited for use at home. We can say that for household use it does not make sense to implement a more complex scheme.
A circular saw can be mounted on both the spindle shaft and the motor shaft. The carriage can be assembled from various parts, but the rollers should fit well under the rail, which will be used as the main guide. If the rails will have visible defects, in the form of bumps, chips, etc., then the carriage may wedge during operation, which is not good.
Disk power-saw bench: 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 homemade one. Of course, in the first case, you will receive a guarantee and a better and more reliable tool. But if you make the proper effort, then you can do the exact same sawmill yourself. Although the guarantee for it, of course, will not be. So, the price of the simplest sawmills that are sold today starts at 25-30 thousand rubles. The most expensive options will cost hundreds of thousands. At the same time, the price of a makeshift 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 is to buy. You must admit that a circular sawmill, the price of which is much lower, and the quality is at a level, attracts much more.
About tool classification
A circular sawmill can cut virtually all roundwood materials. For example, edged and unedged board, bar, bar and so on. Typically, the diameter of the circular saw is 50-60 cm, but if the tool is intended for domestic purposes, it may be smaller. 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 there is virtually no waste after work.
- Angular sawmill - the angular sawing principle is used. The design provides 1 or 2 saws. The saw blades are fed orthogonally.
Horizontal Disk Sawmill
When working with the so-called βstandardβ power-saw bench, that is, horizontal, idle is completely absent . In principle, this is its main significant advantage, which cannot be ignored. Sawing blanks is carried out using a carriage, which 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 main requirements for them are wear resistance and strength. In priority, the teeth should be made of win. This will provide not only an accurate cut, but also the absence of defects, for example, wave-like depressions.
Flail saws
This kind of tool can have either one working body or two. In the first case, the cutting of blanks is carried out in the vertical and horizontal direction. It is also interesting that in this case there is no idle, as in the horizontal sawmill. In double-disc equipment, wood is supplied orthogonally. Two working disks are horizontal and vertical relative to each other. This ensures high performance of such equipment. Although it makes sense to say that the price of double-angle corner sawmills is quite high. It is far from affordable for everyone, and there is no sense in buying an amateur tool. Therefore, let's talk about how to make a sawmill yourself. To do this is not as difficult as it might seem at first glance.
Making a power-saw bench: part 1
If you still decide to make your own woodworking equipment, then you will need a tool. Firstly, purchase fasteners (bolts, nuts, etc.), and secondly, construction goats will come in handy, which in the future will fulfill an important function. The main element is an electric motor. There are no special restrictions. The main thing is that the motor power is not too small. For example, an electric motor from a chainsaw may come up. As noted above, the circular saw is the main working body of the sawmill. It can be mounted on the spindle or motor shaft. If you do not need too much performance and accuracy, you can use the most basic scheme. 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 disc should be slightly above 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 power-saw bench: 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 angular sawmill can be made with the help of several wooden goats, which will be connected to each other by small pieces of boards. On top of this design, an assembly table is made of metal plates with a width of 200 mm and a thickness of 4 mm. Between each other, the plates can be connected with jumpers or screws.
As a blank for the future disk, a steel or duralumin sheet can be used. Typically, the thickness of the circular saw should not exceed 3 mm, and the diameter, as noted above, it is not recommended to take less than 500 mm. Interestingly, the angular circular sawmill can have only a few teeth. Moreover, the effectiveness 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.
Some more interesting points
It is imperative to secure the cutting tool securely . The disc should be clearly in the middle of the previously prepared gap. The mini-sawmill (disk) should have a high-quality guide. To do this, you can use the design of the U-shaped saddle. The formation of the product should be strictly in the shape of the log. For manufacturing, you can use ordinary boards. It is desirable to pre-clean them from bitches 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, above 2 kW is also not necessary. At the final stage, the table is screwed to the bed. Screws are suitable for this. In principle, on this all assembly and installation work can be considered complete.
Conclusion
If during work you take into account all of the above requirements and conditions, then you will be surprised at the quality of the manufactured equipment. In principle, a homemade disk power-saw bench reviews are positive. Partly because it is unlikely that someone will write poorly about their product. It is also a great way to save a ton of money. You will gain valuable 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 make a sawmill with your own hands.
