Re: [CAD_CAM_EDM_DRO] Re: servo motor shaft 5/8 to 1/4...best way??

Come on guys,
McMaster-Carr sells flexible spider couplings, with half
of it having a 5/8" bore, and half with a 1/4" bore, and theyre so cheap, it
doesn't pay to make them. Don't even think about butchering the shaft of the
motor.
