Homebrew PCBs

OK. I can envision a drive to the collet chuck as a separate entity with no problem. For some reason, I was thinking this was about fitting a collet chuck directly to a high speed air or electric motor for PCB milling. And while that can be done, a spider or helical coupling for those speeds would be pretty spendy and the whole assembly would require some careful machine work to be functional.

Thanks,
Donald.
