new Hamilton

[reggaepass at aol.com]

Avery,

  Hard to know for sure when communicating through email, but I think 
Jurgen was kidding about "more is better" where key punchings are 
concerned. I believe fewer are better. When we level and dip keys, we 
also consolidate (a dial pressure gauge is handy for this) and arrange 
in hierarchical order (largest to smallest, bottom of the pile to the 
top). Anyone out there think we are wasting time? If yes, let's here 
about it (maybe I DO have better things to do than measure piles of 
punchings)!

 Cheers,

 Alan Eder

 Jurgen,

  I respectfully disagree! IMO, you get a much more stable regulation 
with fewer punchings! Take out some of the pinks/blues/greens and put 
in a thinner type cardboard punching (or two) and then even it out with 
the others, JMO!

  8 - 10 paper punchings under the front rail felts shouldn't be a 
problem.  That amount, and up to 12,  corresponds to NY Steinway specs, 
at least on the recent D I worked on.  Funny, those Youro Peon piano 
companies - you know: Grotrian, Schimmel and so on - seem to think you 
shouldn't put more than 4 paper/cardstock punchings under the front 
rail felts.  I think they are just being cheap.  A real luxury piano 
has LOTS of paper and cardboard it it.  Too bad the dip is already so 
shallow on the Hamilton, otherwise a person could add more paper!!

  Tuned this new Hamilton grand at dealers just before Christmas. No big 
deal, not great ,but no real major problems. Went back last week after 
a prolonged cold snap here in the NE.
  Key dip was no more than 8mm and regulation was terribly off as you 
would expect.
  Looked under fronts and found about an average of 8-10 punchings under 
each key,also key height is off on several naturals.
 I'm open to any suggestions besides gasoline and a match to correct.
  My first thought is to redo height and dip and then regulate,but could 
this be a key frame problem? Humidity level has not been over 30% in 
this room.
