Found out today that the wire size indications that Yamaha stamps on their 
grand piano bridges are METRIC, not standard sizes.  I confirmed this with 
tech Greg at yamaha corp. When I mentioned this to a couple other techs (who 
have more experience than myself), their typical reaction was, "hmmm, I 
didn't know that". So, for example, 14.5 on the bridge calls for 15 standard 
size. How many on the list knows this? (Probably most everyone but me! :))

Also, since I'm restringing my yamaha G1, after removing the old understring 
felt, i found that the "curved" piece at the beginning of the plain wire 
tenor section (between agraffe and tuning pins) is actually a piece of 
cardboard, covered with thin felt, instead of one thick piece, as in the 
last two sections. Upon further inspection, the underside of the cardboard 
also has an extra strip of the material on one side, and a thinner strip of 
felt on the other, for DB purposes no doubt. I wonder if you can order these 
pieces ready-made, or will i  have to just make a "copy' of it myself.
