I am restringing a 60's Yamaha G-3. Someone previously re-pinned this instrument with 3/0's! That's a jump from .272" (originals) to 286" (Denro's), you can imagine how it tunes! The block is in (otherwise) fine condition, it is fully fit (glued to stretcher), and at this point, I don't plan on replacing it. I haven't done much reaming, and would like advice from those of you who have. Information I would like includes: Purchase reamers from who, (Pianotek)? What size? Ream to .004" less than pin diameter, or more? (I will repin with 4/0 Denro's) Ream by hand presumeably? Use what to hold the bit, guide the angle? Advice on technique, do's and don'ts? BTW, we may all know this, but just in case, Yamaha (and other makers) offer up-size replacement tuning pins for the purpose of restringing. There are two (metric) sizes available between the originals and our standard 2/0 (.282"). They're more costly, but work very well. Many thanks, Mark Cramer Brandon University PS Scott, the CAUT page looks great, Jim's "wisdom" is a real keeper. Anyway you could add my name to the list?
