Reviews of owners


“If you create a saw from the mill with their own hands, then, of course, you do not have to count, it is a complete replacement for, for example, the Makitov saw. I, for example, urgently had to repeat UHM into an electric saw, because it was necessary urgently to cut boards and burned out a chain saw. In the process, I reassured myself a hundred times to make sure everything was okay. “

“Factory devices have been tested on pads for years in a variety of conditions. The protection becomes a “fool”, and here is such a device with crazy speeds and no brakes without lubrication without basic protection. In my opinion, it is better to buy a normal tool or not work at all.

Disadvantages: dangerous to health. “

Anyone who comes to work with wood should have a saw in their arsenal of tools, with which it is much easier to do sawing work. Below is a schematic diagram of modifying an electric saw that can be made from a mill

To replicate the cutter in an electric saw, you need to have with you:

  • A welder;
  • A pipe adapter;
  • A metal roller of small thickness;
  • Reduction;
  • Part visible.

The first thing to do is to weld a movable bicycle to the end of the rod. It is very important to make sure that this wheel and the contour match. If this nuance is not taken into account, the chain will fall off or be severely stretched. Then the cutter adapter is attached to the wheel. The adapter should not be fixed permanently, it must be removable, otherwise there may be difficulties in the work of the enterprise.

A simple and reliable option for refinishing is the following method. We take a tire from an old chainsaw, a sprocket and a chain. We twist two perforated angles. We cut a hole for the mother in the hole. Use the sprocket to fasten the angle to the body.

How to take care of the lawn?

Attach the tire to the remaining corner. Then attach the sprocket and connect the chain. That’s all the manipulation, which means we get an effective saw.

Reviews of owners


I do not consider myself a craftsman, but circumstances forced me to try to make a chainsaw out of a grinder. I needed to cut trees, and even a hand saw couldn’t cut them in a month. So, after studying the information on the net, I decided to buy a suitable adapter on AliExpress. I am not very enthusiastic about everything Chinese, but after I assembled the device in accordance with the drawings in the Chinese manual, I was surprised that it works and saws well.
