Dear List, Well, my number 2 tip fits the pins of the Petrof pianos I tune very snug. Petrof uses smaller tuning pins. But the fit of my number 3 tip I use on other pianos with larger ('normal size') pins is quite jiggly by comparison. I had once mistakenly used the number 3 tip to tune the Petrof pianos and perhaps that ruined my number 3 tip. Using a too large tuning tip for the size of pins will cause damage. What size tuning tip do you use for standard pianos? (ie: Yamaha, Kawai, Baldwin, Steinway, etc.) Thanks, Johannes Spannung
