<HTML>We all know that a hammer is supposed to swing 4 - 8 times. If it is less than 4, then the bushing is too tight. If it's more than 8, supposedly the bushing is not tight around the pin, and that might cause the hammer to wobble up to the string, which will eventually lead to uneven wear on the hammer, whcih creates tone problems, ya da, ya da.  So here is the problem. I've got this hammer with only 3 swings. So that mean the bushing is too tight. Before I take the pin out, ream the bushing, and put in the same size pin, I put a little Protec on the bushing. But now, all of a sudden, I've got 10 - 12 swings. According to the above presumption, the bushing is now not tight around the pin any more. Or is it? Has the introduction of Protec shrunk the bushing to the point I need to ream and repin with a larger pin? Or do I leave the original pin in there, and allow the 10- 12 swings? Wim </HTML>
