My arbor collars are threaded and slightly larger than conventional ones. The two threaded cutter supports thread onto the arbor collars and tighten against the cutter.
After the first pass, I back off the cutter supports, allowing them to sit on the arbor, which has a few turns of tape on each side to protect it and the threaded supports. For the start of the next piece, the support collars go back against the cutter.
