[CAUT] Piano truck installation

[Greg Newell]

Jeff,
         It appears we are talking about the same product. I agree that it 
can and does hold a static weight but then haven't we all heard of a great 
many shade tree mechanics crushed by their car when one of these fails. You 
bring up a good point, though, in that usually the incorrect side is used. 
I'd personally stick with wood though as it's much lighter and less 
problematic than a cinder block. I always seem to have rather raw hands 
carrying cinder blocks any distance no matter how small.

best,
Greg
