Hey here's a relatively easy one. :-) Piano: Sojin Grand Problem: Keys in the treble sticking occasionally and not always the same key(s). Symptoms: Key bushings were free and clear, balance holes were loose almost pully, whippen and hammer flanges free to very minor friction, sticking problem only in treble area but there was a 'slight' occasional ticking noise on every key throughout the scale. The problem seemed to disappear with the action out of the piano, and before the cheek blocks and fallboard were reinstalled. Question: What it was? :-) Jim Bryant (FL)
