I thought the stem of the caster went into a pressed steel socket in the leg. Are we talking about the same thing? > And how easily will the caster > come out of the socket? It's not that difficult to prize one out with a large screwdriver (there I said it - apologies to tool aficionados) but if you do this with the caster installed in the leg be careful to protect the bottom of the leg so that the screwdriver doesn't crush it. Personally, if the caster is in need of this much attention, I would probably just remove the caster and socket together and then replace both. > Will it be necessary to lay the piano on > its side or could I do this > by blocking up the piano one leg at a > time? You could jack up and support the piano and work one leg at a time. I would remove the leg though. I wouldn't attempt to remove the caster or socket with the leg on the piano. > I have never considered > doing this as a standard rebuilding procedure > but it might not be a bad > idea. > > David Love I routinely replace the casters and sockets when I rebuild a piano. They're cheap, the new ones look better, and I like the piano to actually roll when I push it around. Phil F Phillip Ford Piano Service & Restoration 1777 Yosemite Ave - 215 San Francisco, CA 94124
