Heintzman 186 Conservatory Grand Problem

[Greg Newell]

Dave and list,

                I had this problem and reported it to this list maybe a year
ago or more. It was on an old Henry F. Miller that had never had the action
out in its' lifetime. Everything was original and it showed. The problem, I
discovered, was that the entire plate was bowing down in the middle while
the string tension was up. Once I removed the tension in preparation for a
new pin block the plate flexed upwards allowing the action to slide out
easily. Did I mention that the plate flexed up .. way up? The fix after the
pin block was to make sure that the plate horn wedge did not fall out this
time. After that it all behaved quite normally. Hope this helps.

 

All the best,

Greg Newell

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.
