Yamaha U1's and double wheel castors

[David Skolnik]

David -
I did a set a year ago.  I believe they were plate casters.  The problem I 
had was with the width of the head of the screws they supplied.  In order 
to allow the caster to rotate unimpeded, I had to significantly reduce the 
original head width.  I think I chucked the screws (16 of them) into 
a  reversible electric drill and took them down on a belt sander.

Also, it does change the height, most noticeably at the pedals.  Lastly, 
these casters need brakes.  It is very easy for the piano to begin rolling 
away from the player, especially if there is any incline at all...but they 
DO       save the floors and your back.  Good luck.
