That dadgumed short SD-10

Hi Elwood,
                     Order a new set of Concert grand legs with the big 
wheels and brakes.   Then get a welder to make up a frame with 1" tubular 
square steel.  Add a cross piece between the forward legs of the frame 
About 9" behind the pedal lyre. Weld a flange at the end of each leg of the 
frame and lag bolt to each leg. Paint your favorite colour of black.  This 
will make the legs just as rigid as the stock dollies.  Esthetically it 
looks a lot cleaner.  There will be far less Jiggle when the piano is 
played vigorously.
The piano is firmly connected to the floor. Weight is still on the legs, no 
vertical flex from the frame.
I modified one for a church several years ago, there is no down side even 
wheeling it from carpet to a hard wood floor area.
Regards Roger
