<DIV> If you use veg-tanned leather there is not a co=
rrosion problem with the pins. Chromium tanned leathers are the corrosi=

<DIV><FONT size=3> After following up on many of our high use re=
builds I am extremely disappointed at the extreme wear factor on all th=
e bushing cloths we've tried. It's primarily the front rail pins. In on=

bushings are gone & keys as sloopy as before </FONT></DIV>

<DIV><FONT size=3> I'm currently reworking a 1958 7 ft Petrof. =
Nice piano. The center rail bushings are in perfect tolerance. The fron=
ts were felt & we changed those due to exessive slop.</FONT></DIV>
<DIV><FONT size=3> There may be a chance of corrosion on brass =
but right now I'd take my chances with the leather even on the brass pi=
ns. Hey if they last more than 2 years under heavy use then I'm even, i=
