I am looking for a coupling to use in a work-holding system on a CNC router 4th (rotary) axis: there must be no backlash or lateral movement, but it would be highly advantageous if either the whole coupling could be easily secured/removed to/from the drive shaft via a split end and clamping screws, or if the coupling halves could remain on the drive shaft and face plate respectively and be simply inserted into each other to place the work-piece in position.
At the driven end is a 1.625" dia keyed output shaft from a gear reduction drive, with a conventional lathe tailstock and live center at the outboard end. The live center may drive straight into the wooden blank or into a faceplate screwed to the blank; I'm undecided about that at this point.
The size and weight of the blanks and the need to set them in place one end at a time makes this sort of system necessary - at least that's my present thinking!
Advice would be appreciated, thank you.
