The jack I use is Starrett's "Little Giant" Jack Screw No. 190. It is 1.25
inches diameter and screws from 2.25 inches high to 3.375 inches. They are
usually supplied with two extension bases, 1" and 2" in height, and these may
be stacked. The head of the jack swivels a little bit to accommodate
surfaces not quite parallel, similar to the tip on a C-clamp screw (G-cramp
for you Englishmen). There are other tips and bases available for working
with pipes, rods, etc. Starrett says they "easily lift 1000 lbs." and they
do. Pianotek Supply is a Starrett dealer. (800) 347-3854.
