I use a diamond cutting blade for straight cuts on a home made mini table saw. I duplicate parts with a router mounted on a small router table (bought at a yard sale real cheap) with carbide cutters, or Tungsten Carbide Dremel bits that I can put on the router with a modified adapter from another power tool.
I made a 6 mm CF motor plate.
Here's the tranny and motor all complete. You'll see what the stuff on the rear of the motor is for in the next pics.
I made this part out of a piece of aluminum angle.
It goes here and that threaded rod on the motor slides in the slot. With a couple washer and a couple nuts, the rear of the motor is supported very well.
