This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Tom, is this a Samick? I've been encountering a lot of them with = the problem you describe. The flange is really binding up, and when you = re-pin you notice a nice black ring on the old pin. I took some of these = home and looked at them, and sure enough, the plating was gone on one = side of the pin. What I've heard is that if they use a cheap low quality = of flange pin, the plating comes off, goes into the cloth and grinds = against the pin ( my conception of what's going on, I could be wrong, = wouldn't be the first time. ) Anyway, re-pinning has always worked for = me, never had any problem after that. The trouble is, how many flange = pins are there in a piano, anyway? That's a heck of a lot of work.=20 So, of course we're going to try to find something else. You could = try soaking the flanges with 50/50 methanol/ water, tell them that the = piano pretty much won't be playable for a day or two, and see what = happens.=20 =20 Just re-read your post before I hit send. You mean you're just = re-pinning without reaming? When "I" say re-pinning, I mean pushing out = the old pin, running a set of the Mannino reamers (Schaff, $12, or so; = the best thing since sliced bread. ) through the cloth, and then = re-pinning.=20 There's a good article on this in the technical exam source book, = available from your friendly PTG office.
