Doc and Alpha,
Thanks for the reminder on burnishing. And given the info on the Elliott burnisher you listed, Doc, that is pretty impressive, even to a jaded finisher.
.05-.2 microns? Zoiks!
ANSI/CAMI 2000 grit is ~15,000-ish mesh. That's about 1 micron.
This burnisher produces a finish comparable to a mesh of over 100,000.
You can get abrasives lower than that, but wow. That's mighty smooth.
But again, is this the method used for stainless?
