In this review, we consider another construction of a grinding machine (grinder), assembled on the basis of the electric motor.
You must first make a base frame on which is located the motor. Weld it from sections of profile pipes.
Mark up, drill the mounting holes and cut the thread. Fasten the motor to the frame using bolts and nuts.
Then weld to the frame is a piece of shaped tube, and to it — another preparation, a perpendicular (see photo below).
If there is no suitable motor, table grinder, you can do based on a small grinder.
Aluminium the author molds a block of the desired size which will be inserted into the core tube.
In this drill the mounting holes, then fasten the metal plate to which are attached rollers.
Videos the author also made from aluminium. On a lathe make seats under bearings.
Fasten two clips to the metal plate. On the motor shaft, the author has established a large drive roller (made of aluminum).

Prepare the required details, and then collect the last node with the roller for tensioning the sanding belt.
Fasten it to the motor housing. To the profile of the pipe weld a piece of metal with a hole to connect the return spring.
Pull the sanding belt, and a homemade grinder is ready for operation. How to glue a sanding belt with your hands, read here.
The Assembly process of a grinding machine you can see in the video below. This review was prepared on the basis of videos from YouTube channel Cypsmen.
