[pianotech] Yamaha U1 casters

[John Ross]

Plate casters would eliminate the chiseling, but would make it a bit higher.
How about cutting some hardboard inserts, to raise them enough so they 
rotate freely.

David,
 If you want to put on the Darnell 2" casters, I think you may be stuck with
the "chisel & shim" you spoke of.
I am answering your question to ask if installing the twin piano dollies
would be an option in your situation.  Not quite as neat in appearance when
you are through, but quite functional and maybe less hassle than changing
the design of the casters on the piano.  Just wondering.
Good luck.

Does anyone have a standard procedure for replacing these? They are small
diameter (roughly 1 1/4"), the front ones are taller overall, are recessed
into the leg and have no stem to speak of, the rear pair are shorter but are
not recessed, and do have a stem. This one wants to roll easily in a school
room so I want to put on the 2" rubber darnell casters and guess I'll just
have to chisel and shim until I get them level. As usual what looked like a
simple task is needlessly complicated. If anyone has experience they want to
share I'd appreciate it.
