  Hi Joe, I'll play with the sockets and see if i can't get you a good 
measurement. Honestly, there never seemed to be any need to measure 
this, you get your pinblock stock drill a few test holes and pick the 
one that feels best. Easy. Sabathil was a harpsichord shaped object at 
best, you may have a real struggle on your hands. You might be able to 
get a tuning hammer with hook from Lutz Bungart at www.fortepiano.com, 
he had some very nice ones last time i checked. When you change a string 
simply use a paper shim (I use acid free rag paper just to be cautious) 
about 1/4 the diameter of the hole and it's no problem. These pins don't 
wear out the holes the way piano pins do. Old school pins are tapered 
and you can tap them in to tighten them up. I wouldnt blame the beech 
for the pinblock problems, it is good material, probably a flaw in 
construction. Hope this helps!
