Hmmm? I tend to disagree, if the slot is "naked/bare/whatever". What, exactly would you "burnish" with? Why? What are you acomplishing by doing this "burnishing"? IMO, the brass spring will do it's own "burnishing". The best situation, I've found is to have sufficient resistance in the balancier pinning. (3 to 6 grams), and, a CLEAN spring & groove. This has proven to give the most even/lasting results for me. Of course, YMMV.<G> Joe Joe Garrett, R.P.T.

Whether the slot is naked, or coated with graphite, permalon, or other substances, burnishing would help the situation considerably.

IMO, no lubricant is adviseable! No need. The lubricity between brass and hardwoods, such as hornbeam and maple is sufficient and consistant. Joe Joe Garrett, R.P.T.
