This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Funny you should mention bad felt John. Just last week I spent a day = doing some refurbishing on an old original M&H upright from the 1890s - = quite respectable shape for its age. I was putting all new felt on the = keyframe and leveling keys, but the lady wanted to minimize costs, so = the key bushings were OK and I figured I would not do anything with the = keypins. Upon removal of the center rail pin punchings, I noticed that = the center rail keypins were all corroded just at the bottom where the = felt punchings were. The front key pins were fine - no corrosion. But = the center rail pins were trashed - I had to replace them. Bottom line = though, I can only assume the two rails had been exposed to similar = environmental conditions for the past 110 years, but only the center = rail pins corroded - likely the felt punchings I presume? I wonder what = it could be about the felt that would cause corrosion like that.
