I claim no extensive experience, but I will tell you what we have been trying to do, with some success. The process was derived from work I did with Dan Mansolino a few years ago. I have had a Steinway L #410xxx in the shop for restringing which I believe had 3/0 pins which were not particularly loose. I restrung with 4/0 pins (Amsco, I believe) and got a torque of around 200lbs. with major snapping. I replaced some pins with 4/0 Diamond brand which felt better but not good. I then used a straight decimal size chucking reamer (.284") in a lightweight electric drill, then repinned with 4/0 Diamond brand. The torque went down to 100 - 120 lbs. and the snap disappeared. I believe Dan would have preferred a spiral reamer, possibly with a reverse spiral, but they don't seem to be available. I don't know if the torque will drop to an inadequate amount over the next few years. I'll have to get back to you on that. I got the reamers from MSC INDUSTRIAL SUPPLY 800-645-7270. I bought a .282, .283, and a .285 as well, but felt the .284 to be the best in this situation. It seemed to get dull however so I bought a few extras. Let me know if I've left out something critical. BTW, I've also had to do a fair amount of grinding of the plate tuning pin holes due to pins rubbing. All quite time consuming Regards- ----------------------------------------- David Skolnik Manhattan School Of Music dskolnik@msmnyc.edu 212-749-2802 Ext. 455
