> a new Bolduc quarter-sawn (more-or-less) hard-maple pinblock. I am using Ron Nossaman's two-bit > drilling method. I started out with a final drill size of 0.25-inch > (actually the drill bit that Pianotek sells specifically for the Bolduc > blocks - it is actually about 0.247-inch). I was consistently getting >an initial torque exceeding 200 in.-lbs. . I am getting an initial torque (right after pounding the > pin to stringing height) of about 180 in.-lbs. Yikes, this is WAY too tight for finesse. I use the Bolduc blocks with 1/0 pins and a C drill. I drill them in one pass. Average beginning torque is 130 in/lbs, after one year I see near 115 in/lbs. The oldest block that I have done this way is 5 years old and it is still at 110 in/lbs and tunes like a dream. That particular piano got tuned 85 times last year,(recording studio, where every tuning has to hit A-440). I use a D bit in the top octave, it reduces the torque by about 10% and makes the top end a lot easier to tune. I use the 1/0 pins because if there were to ever be a problem, I can solve it with a "normal" pin.
