[AT] Neat jack idea

[charlie hill]

Hi Hank,  I agree with you.  I think our definition of cribing is not the 
same.  I'm speaking in terms of the way a  house mover would crib up a house 
before putting the beams under it.  If you support it that way it won't 
matter which way or how it falls the cribing will catch it.  Jack stands are 
good on concrete but I've seen them bury down in dirt and turn over.  Again, 
that depends on the design of the jack stand.

Anyway we both believe in doing it the safe way.

Charlie
