Hammer Shank Flange Friction Question

[Joe And Penny Goss]

Hi Terry,
Use your gram test gage. I find that Protech reduces the friction from 10
down to about 7 or about 3 grams.

Subject: Hammer Shank Flange Friction Question


> I am going through a YC small grand action for a customer - new brackets,
level keys, regulate, arc hammer tails, get friction in the right ball park,
align hammers, etc. No concert pianists in this home (beginners only). 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?
