New wheels for a Yamaha U3

[Dean May]

 >>       I've installed twin dollies available from Schaff or Jansen many
times on school pianos and they work very well  . The Schaff set is
around $100 and Jansen $120. I'm not sure if there is much difference
between them but I'm not sure. Maybe the Jansen set has better casters.


Just a word of caution: The problem I've seen with these twin dollies is
that they don't support the piano where it was designed to be supported,
particularly the key bed, which allows sagging. I've seen pianos in
institutional settings with these dollies with regulation problems and
eventually loose keybeds.

David,
        The U3 may not accept a larger wheel without them binding on the
case.

        As for installation, I use the tilter, position the dollies to
line up with backposts as possible and screw the dollies to the bottom
(pilot holes first) using pan head screws. Tilt the piano back to the
floor (trust me guys this does work) and then screw the dollies to the
back with hex head lag screws. You may only be able to get three of the
four holes to line up on the back of the piano. The whole operation
takes about 30 minutes (excepting the two miles you have to schlep the
tilter from the parking lot to the piano!)
