[pianotech] new Steinway casters on old steinway legs

[David Love]

I stand corrected.  The #977 on page 151 may just work fine.  Will check it
out.  Didn't see that, or forgot about it.  May have actually used that one
before now that I see it.  Getting old :-(.

I'm still confused about a few things:
you say this is a 1920's O, but that the Darnell caster (Schaff 596A) is an
easy retro.  That can't be the original caster, I'm sure.  That would have
been one of the 'Faultless' style, on page 151.  Also, the stem on 596A is
Darnell's 'O' stem, as opposed to their "M" stem, (as on Schaff 2591 and
2592).  The socket, whether square or round, would have been the pressed
steel, not the heavier, cast version.

If you think that a nickle version of the Darnell is what you're looking
for, you should talk to them directly
http://www.casters.com/darnell_rose/contact/contact.html

More confusion:

You say piano won't be moved around, so why are you concerned about bearings
rattling?  And if it is to be moved, on a wood floor,  are you sure you
metal at all?

You say the bearings are sealed, in the new casters, so why would replating
affect them?

I just saw some (presumably new) European casters that are like the ones on
Schaff page 153  (similar to 2065B) except the wheel is covered with a layer
of high density rubber, to protect the floor.  Quite elegant.
