Jim, This probably is not a solution to the problem you are having, but I want to get this information out to the technicians. A customer has a 1980's Bosendorfer 6 1/2 foot piano. After tuning it for about 10 years some bass-tenor notes started clicking on a hard blow. The bottom line: The hammer shanks were hitting the pinblock. I had to bevel the edge of the block. ---Tom Gorley > Tom Gorley > Registered Piano Technician > (650) 948-9522 -------------- next part -------------- An HTML attachment was scrubbed...
