Today it is difficult to imagine a modern private sector without a chain saw. It is an indispensable tool for many jobs, especially when it comes to repair and construction. Therefore, its presence is fully justified.

But not all people have the opportunity to purchase such a tool for the money. After all, such a power-saw bench is not so cheap, and buying a quality tool is not easy. This prompted specialists and craftsmen to develop an uncomplicated technology by which you can make a chain power-saw bench with your own hands.
Preparation for work
Before you start working directly on the tool, you need to decide where you place the sawmill. The best places for this are the garage or workshop. After all, the power-saw bench is a rather heavy instrument in terms of weight and overall in size. Therefore, it is recommended to install it right where you plan to work.
Some people store sawmills in the yard. But it is not recommended to do this for the reason that the open-air power-saw bench can deteriorate. Therefore, if you have no place to store it, then you need to take care of at least a minimum shed.
When the place is selected, make sure that the tool is available. For power-saw benches, it is best to select a metal of good quality, on which there are no signs of corrosion, cracks and holes. From this, by and large, will depend on the level of reliability in the future. So, you will need:
The scheme of fastening the brackets and the rod of the sawmill.
- two channels of steel with a height of 2 cm and a length of about 9 m (dimensions may be different depending on what personal preferences and opportunities you have);
- sections of metal water pipes;
- powerful puncher;
- metal corners;
- thick bolts;
- welding machine;
- metal blanks for racks;
- wooden bars;
- steel plate, the dimensions of which are slightly larger than the dimensions of the electric motor of the future sawmill, and the thickness is about 5 mm;
- rubber gaskets;
- steel plates;
- special chain, which is purchased separately (it is best to take a new chain, checking its quality at least visually).
When selecting the main billets of metal also remember that all of them must be perfectly smooth. If at least in some places there will be distortions, then a chain-saw power-saw bench with your own hands will turn out to be of poor quality. And this, you will agree, will not at all please.Back to table of contents
Preparation of blanks
Now is the time to get to work. To begin, free up the area where the sawmill will be located, from debris and unnecessary items. It is important that this place is as flat as possible. Therefore, in the case of an uneven surface, it is strongly recommended to level it.

Now take two main channels and at the same distance from the edge along the length (about 1.5 m) drill the same holes with a perforator. Further, the same distance along the entire length is measured from the holes, markings are applied and drilling is performed in the same way. As a result, you get a few holes. The main thing is the equal distances between them and the observance of their parallelism on channels relative to each other.
Now you need to calculate the total number of holes. And in the same amount prepare pipe sections. The length of each tube is approximately ¾ of the length of the channel. But the thickness can vary from 2 to 2.5 cm. The connection with channels is made with the help of bolts, for which holes are drilled in advance with a perforator.

Manufacturing and mounting racks
Next you need to make racks on which the tool will hold. Ideally, you should get 4 identical thick racks that are fastened to the channels with the help of all the same bolts or welding machine. If the estimated length of the unit is large, you can use more racks for reliability. Here you have the right to decide for yourself.
But before bonding you need to install on the stand frame. Carefully ensure that the racks are at a distance of about 0.8-1 m from the edges of the bed. After that, you can safely make the connection of the bed with the racks as described above.
But, in order for the tool to be quite strong and reliable, it is necessary to make a lower fixation. For this, wooden blocks are used, which are enclosed under the rack. Try to do everything right away, so that the tool does not skew.Back to table of contents
Trolley manufacture, engine and chain installation
Next, make a movable cart. Take the metal plate, in the upper part of which you fix the corners and gaskets. From the bottom side, the same corners are placed on the bolts. In the upper part in the pre-marked places are mounted clips and holders. After checking the reliability of such mounts, an electric motor is installed on the upper part and fixed there between the corners.
You just have to tighten the metal chain so that the tool with the electric motor can move freely. The chain must be tightened as much as possible, since in case of sagging it will not give the expected result and high-quality movement of the unit.
Fixing the chain is made in two prearranged places using bolts.
A few words should be said about the characteristics of the saw itself and the electric motor. The engine is quite suitable standard approximate power of 10 kW. A saw can be about 1 m in diameter. But do not forget: both the engine power and the size of the saw can vary according to your wishes. The smaller the size of the saw and engine power, the smaller the dimensions of the base. And vice versa.
So, the chain sawmill is made by hand.
She is quite capable of any healthy man. But if you feel that you yourself can not cope, it is better to ask for help from a friend or specialist. And next time you can already try to work independently.
