Many, including me, use the Beall buffing wheels. There are three wheels, two for polishing compounds, one for wax.
When I bought mine long ago the package included one threaded 2MT arbor to swap between wheels. I purchased to extra arbors to make it quicker and easy to change.
Later, they offered a long shaft you mount on the lathe between head and tailstock and holds all three wheels. I personally don't like this since it limits access to the wheels in certain situations. And it takes more storage space!
Buffing balls are also available to polish the insides of smaller bowls and such.
