Then that makes it easy! I would start by drilling a few holes in the =
pinblock of different diameters outside of the tuning pin fields, pound =
in a few tuning pins and test the torque. Once you have found the =
optimal sized hole, ream out a couple existing tuning pin holes with the =
same sized drill bit - maybe the three holes for C-88 - pound in some =
pins and test the torque again. Adjust as needed. Even if you end up =
drilling a few holes too big, you can always plug a couple and redrill - =
no big deal. I don't think you are ever going to find any specifications =
that are necessarily going to work on any given pinblock - your block is =
older than new, it has been toasted a bit, it may be at a different =
moisture content, being re-drilled my affect things a bit (just like if =
you are drilling a new block, you will often use a different final bit =
size if you are drilling in two passes compared to a one-pass drilling =
technique). I find the only way to be sure is to experiment with a few =
and test.

    OK so here it goes again.

    Have you removed the plate?
