Heintzman 186 Conservatory Grand Problem

[piannaman at aol.com]

 Roger, 

I have this problem on an old Sohmer grand.? I can get the action out, but it is a challenge due to pinblock delamination, causing the block to dip downward in the center of the piano.? I'm letting it go for the moment, as I didn't cause the problem (just found it....), but would like to get it taken care of at some point.? The piano is quite tunable at the moment, but this this problem makes me nervous in terms of long term piano health.? 

Any suggestions will be most appreciated.

Thanks,

Dave Stahl

Hi Glenn,

?????????????????
A not so uncommon problem with some Heintzman grands, is pin block de
lamination.? If some bright spark tried to tap a few a few tuning
pins with out supporting the block.? Then Bingo! that will be your
problem.
