One of the D's on our stage has a bowed truck. I tried solving this problem 
by taking the weight off the legs, and tightening the bolts on the center 
plate. But it didn't do the trick. The bolts that hold the little plates 
under each leg are about 1" from the floor. I don't think, however, that it 
lowers the keybed that much. I think we're only talking about an inch or so. 
The problem with the SD10 might be more than it just sitting a truck.

If your pianist has a problem with putting his legs under the piano, it might 
not be because the piano is sitting on a truck. I wonder if it is because the 
keyframe is lower. If you have both pianos, check both measurements. There 
are two measurements. One is from the floor to the top of the keys. The other 
is the distance to the underside of the keyframe. It would seem to me that a 
pianist would feel the difference if the keys were not at the right height. 
But if one has longer legs, he would notice that there is no room under the 
piano. 

Does anyone have one of each, and can check this out?
