Hi Dennis,
    I get the rail off and back on within half an hour. Another half hour to
scrape off felt, cut new, glue, let glue set a bit. It's a standard
procedure for me (usually to cure knocking noises where the felt has
disappeared on several notes, due to the upstop being used as a pedal stop).
First time I guess it probably took a bit longer. Well, I know it did,
because I used titebond to glue the felt, didn't allow enough time to cure,
and just as I was maneuvering it around the bend, the felt came off one end.
Curses! It all comes back to me <g>. But the subsequent times were not a
problem.
    As for solving the groove problem, what occurs to me is small pieces of
veneer tacked on each lever with a couple drops of your favorite glue. Could
be done pretty readily with the damper wires removed, tray pulled.
