I had been using various buffing systems for years before Beall came out with his system for woodturners. His system is worth it, better quality wheels and good quality compounds. All compounds are not created equal. The Harbor Freight are the Harbor Fright of compounds. The grit is all over the place, the wheels, are okay, but not what I would call top quality.
I used to buy my wheels and compounds from a jewelry makers supply house and Eastwood, but found Caswell several years ago, now they are my preferred place for buffing supplies. In y opinion Beall is equal in quality, but does not have the wide range that I used. I had dozens of wheels, one for each compound, one set for silver, another for steel and another set for wood. Big wheels, small wheels, and buffing mops. I still use the Beall compounds, but also have a few others from Caswell.
