For badly worn hammers or removing a lot of felt on new hammers I start with 180 = or 220 grit strips, then finish with 600 or 1,000 grit. =20 You'll just have to try to catch one of my voicing classes. Those who = have seen one can tell you that I remove quite a bit of felt with that 1,000 = grit paddle! It's all in balancing pressure and speed. =20 Some hammers do respond well to rougher grit, so I keep that handy as = well, in both paddle and strip form. Since I work mostly on new or fairly new pianos, though, the large paddle gets used probably 90% of the time. =20 Don Mannino RPT =20 =20 ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
