Pinblock too low

[G GRAVINA]

Mike,

Had same problem with a pair (not one, two!) Sohmer grands at a local 
HS.  Original pinblock, as far as I can tell.  Previous tech's answer was 
to grind off tops of drop screws!  In your case, a power planer might be 
cleaner than a grinder for removing pinblock material.
