A home-made electric file (hand grinder), assembled on the basis of a small angle grinder, is a worthy alternative to an ordinary file and whetstones with sandpaper. To make such a tool is not difficult at all, and even the simplest materials will be required.
The first step is to cut a piece of square plate that is suitable in size from the sheet metal. In it, the master drills a large hole for the diameter of the "neck" of the angle grinder. Then the plate is attached to the grinder.
Next, the master makes the marking on the plate, removes it and with the help of angle grinder cuts off everything unnecessary. Then the plate must be bent approximately in the middle under 90 degrees with a hammer, pre-clamping it in a bench vise.
The main stages of work
The bent plate is again attached to the grinder. Next, the master welds a piece of steel pipe to it. At the end of the pipe, it will be necessary to make 2 longitudinal slots. Then the master cuts another piece of pipe of a smaller diameter.
To the second pipe it is necessary to weld a piece of a square profile end to end. The master welds a steel washer to the free end of the round pipe. And in the profile is a "nest" under the bearings.
At the last stage of work, the master installs bearings in the profile pipe, after which he performs the assembly of the entire structure. And then you just have to put on the sanding belt, and you can get to work.
