Tuned an Acrosonic (circa 1955) today with extremely slow hammer return. Client asked me to give her an estimate on bringing the instrument back to good playing condition. Opened it up to take a look and found white powder all over the place, mostly on that rail (I don't know what to call it...) above the capstans that the stickers protrude through. Smelled it and it smells like talcum powder to me. I think this is the cause of the slow hammer return. If so, do you think applying Protek CLP to the hammer butt flange will do the trick? (I gave her an estimate on the lube job, but not for re-pinning...) Tom Sivak
