I thought it was a pretty neat idea -- I wonder if this
might help out some of those old Steinway parts? If Don is
right, though, the crud is the crud is the crud, and it's in
the wood because the whole part was dipped. But without the
copper to mess up, perhaps rebushing might be enough to
make the parts usable? (Not holding my breath ...) They
were awfully pleasant parts otherwise, lightly built, nicely
made, geometrically appropriate. It always seems a shame to
toss them, and put in something heavier.

Gordon, if you don't like copper, can you imagine the mess if
the pins had been ferrous? Real rust, red rust ... but maybe
stainless might do the trick. Pointing them wouldn't be all
that easy ...
