If you prefer to do your buffing on the lathe, and your lathe takes a #1 or #2 Morse taper, these attachments will allow you to mount your buffs securely and still utilize the quick-change feature of the Combination 1/2-5/8" Adaptor. The tapered end is threaded internally to accept 1/4"-20 all-thread (available at any hardware store) so that you can lock it into your lathe's headstock. The other end is a 5/8" diameter rod machined with a flat to accommodate the set screws in either the Combination or Goblet Buff Adaptor.
