Slip the blocks under the steel ..... arm?.foot?... flange? thinghy that 
supports the leg. Right where the castor would be. That's where the flex 
is, when you push down on the keys. A 2X4 like you would use for stage 
truck installation is fine, painted black. I've experimented with smaller 
blocks, made of pinblock material, and covered in player cloth. They work 
also, but the taper has to be very close with a smaller block. With a 
slightly larger block, it's easier to lift a hair and kick the block under. 
The main thing is to have blocks that the stage crew won't loose every 
performance. If the block is only supporting the nut, or bolt head that 
protrudes from the bottom, it will soon develop a divot. Not bad, but it 
can quickly reach a point where it appears to be supporting but may not be. 
So.... support the flange itself, not the nut/bolt. Make sense?

Try it, you'll like it, guaranteed.
Later,
Guy
