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.
