I just found a Handler 60c Dental polishing unit for only $200. It
has a Red Wing high speed and low speed motor on it with suction,
filters, hoods, lights, etc. The motor has two slightly tapered 3/8"
shafts with a quick chuck release thingy on each side. I want to use
this foe jewelry polishing and buffing, but I’m unfamiliar with the
tapered shaft and the chuck release thingies. It’s obviously a very
specialized piece of equipment. Does anyone use one of these units
for jewelry polishing, and if so, what do they put on the shafts to
use buffs, etc.
