When useing Protek or any other such centerpin lubricant I like to apply and let rest over nite on the kind of job you are doing. Proteck doesnt allways work as advertised, nor does any other CP lubricant that I know of. It depends on what the cause of the centerpin friction is. Waiting overnite will pretty much show you how your centerpins are going to be in the long run after application. That way you have a better picture of which flanges need new pins and which dont.

The hammer shank flange friction is all over the place - some are OK (three to five swings), some are totally loose, and some are tight (one or two swings). My plan is to repin as needed, and use Protek on the tight ones if possible. I know many techs use Protek on hammer shank flanges. But if I put Protek on one of the tight flanges, the swings will go from one or two swings (too tight) to seven or nine swings (or more - too loose). I realize repinning will get me the right friction, but I am also trying to do this job as economically as possible for the owner. Is there some way to manage the Protek effect? Is there some way to utilize Protek on the tight flanges without making them so loose? > > Terry Farrell > > _______________________________________________ > pianotech list info: https://www.moypiano.com/resources/#archives -- Richard Brekne RPT, N.P.T.F.
