How often do you need a jack-in -the-box?

[Phil Bondi]

Julia, am I missing something here?

If you attach the lyre to a piano that has no casters, and 
as you say:

 >the piano has no casters and isnt high enough to do so<

Won't the piano be just a tad wobbly?

As far as the tool is concerned..I never plan to make any 
money with the first purchase. I don't own a jack myself, 
but I do have the Piano Horse. I've used it a number of times.
