I got the Beall wheels a number of years ago and I have never even thought about looking further. They're (I think) a US-made set of three 8" fabric wheels. Each wheel gets softer as you progress. There is a first wheel that I use with a (supplied) Tripoli compound, a second wheel that I use with the (again, supplied) white diamond compound and a third wheel (which I don't use) that comes with a carnuba wax block. My set came with a #2MT adapter that fits my lathe headstock. I then screw a wheel into the adapter, hit it with a little compound and buff. Speed is your choice but I usually stay 800-1000rpm. Some go faster.
Note - Prior to buffing on the Beall wheels I wet sand to 3000 and then polish with Novus 3 & 2.
The whole process is probably overkill but my pens have a mirror shine that I don't see duplicated very often.
The only drawback (other than time) is that much sanding and polishing requires a bit more CA on wood pens and OCCASIONALLY I'll sand through to the wood. Just takes a little extra CA and caution to prevent that.
Good luck!
