[CAUT] unmusical caster noise

[Porritt, David]

Jim:

We had a piano here in a small auditorium and it was on a stage truck.
The people who put it on the truck put one locking wheel on the bass
side, and the other at the back.  One energetic player had trouble with
the piano moving as she played and of course it wanted to move in a
circle.  Though the back wheel was locked, there was so much more
leverage back there that it did move.  I think mechanically it just
works better if the front wheels have the brakes.  Of course it wouldn't
hurt to have all of them locking.

Thanks Ron,

I'll try it.

This may be a dumb question but is there any reason why the locking
wheels are on the front, and the non locking one is on the rear? Or, am
I ignorant and all three usually ARE locking casters?

Thanks.
Jim

Try swapping it with one of the front ones. It may work, or if
not, may give you a clue why it's doing it in the first place
once it's out.
