Rotab first real job, countersinking motorcycle spoke holes. 

This was supposed to be a "short" but I made the video too wide for that. I made shorts version to comply with the rules. That can be seen here • My rotary table .
I converted a 200 mm manual rotary table to one driven by a closed loop stepper motor. The initial motivation was to have a 4th axis for my CNC mill but I wanted to retain manual control, not necessarily manually powered. I added a closed loop stepper and made a control box. This video shows its first real job, countersinking spoke holes on a motorcycle brake hub. A simple job but the powered rotab saved a great deal of time.
