hammer rail sandpaper query

[Tvak@aol.com]

List

I need to replace the sandpaper on a hammer rail.  The hammers won't stop 
drifting side to side, and the screw holes are not stripped.  There's just 
nothing for them to grip to.  (The piano is a 1907 6'10" Kimball grand.)

What grit?  What glue?  Removal of old paper? (not sure if there was any 
there to begin with)  Will this cause any regulation problems I should be 
aware of? (Not that the piano has any semblence of proper regulation as it 
is...) 

Any caveats or advice appreciated, as I have never done this before.

Thanks,
Tom S
