Pinblock too low

[Greg Newell]

Mike,
         I encountered something exactly like this after I had sent my 
customers piano to a rebuilder and it came back as you described. I told 
the customer it should go back but they refused as it had already been at 
the rebuilders 2 months longer than expected. Since I had to resolve the 
problem myself I went at the underside of the pin block with a (initially) 
sharp chisel. I peeled off two layers cursing under my breath the whole 
time and hit many a low tuning pin in the process. When all was said and 
done it regulated fine and is a fine instrument today but Oh what an ordeal 
that was! Not one of my proudest moments sending it to that fellow. FWIW
