Double pulley manufacturing process

A blank of the required length is cut from the blank.

It needs to be drilled in the center and installed on the motor shaft.

The essence of the process is that the workpiece rotates on a motor, while cutting the mounting holes for the belt is done with a grinder. It is necessary to start the engine and approach it from such a direction that the direction of rotation of the workpiece and the grinder is towards each other, otherwise the abrasive discs will be erased with virtually no result.

First, an even groove is cut on the workpiece, then it needs to be bored to fit the shape of the V-shaped drive belt. During operation, the latter must be constantly tried on until it fits perfectly.

Using this method, you can machine a single, double, triple or any other pulley. The process is not fast, but it is cheap. The price is a blank and a pair of abrasive discs.
