    I built a support box exactly like Susan Graham's (November 1988
Journal, page 14; picture of box on front cover) for jacking up grand
pianos in order to work on the legs, casters, etc.  The only difference
between hers and mine is that she used 3/4" plywood and I used pine
boards (1" x 8").  

     I've only used it for smaller grands so far and I'm wondering if it
will support one side (one of the front corners) of a 9-ft. concert
grand.  I suppose I could just go ahead and stick it under there and
start jacking it up and see if the box looks like it's gonna hold, but
it seems risky.  

    Don't know if the CD version of the Journals has all the pictures of
front covers.
