Asynchronous 3-phase motor grinder

This is a desing of several parts to turn cheap asynchronous 3-phase 120 Watt motor into a grinder.
Set consists of:
- shaft flange;
- grinder safety cover;
- switch button case;
- capacitor holder.

I've bought an ancient (1962) motor grinder fort 10$, and it was made mostly of wood and plywood pieces. Now it become more compact, safe and reliable!
