    I'm using the Oldham style couplings from CNC4YOU on my build. On the NEMA23 they clamp around the shaft with no other locating method (the NEMA34 motor has a woodruff key in the shaft, so I'll cut a corresponding slot in the coupler).
    p
    What's everyone's experience using these? Do they slip at all or is there not a problem. There is a flat on the NEMA23 motor shafts, so I can drill and tap the couplers and add a grub screw locking onto the flat if its worthwhile?

    Appreciate any advise
