Hello all:
I'd like find more information about acquiring or making knife edge
bearings. They are for use and experimentation in my kinetic sculpture
work. I am doing a series of experiments with balance, center of
gravity, and movable pendulums. Knife edge bearings are typically found
in balance beam type of scales. If constructed properly, I think they
will allow partial rotation on 2 planes. Left-right, forward-back. Can
anyone suggest references on this subject? I have been unable to find
anything specific to designing, making them or using them.
Thanks for the help.

Check "Dual axis pivot" subject around Jul 7 2004 involving Ned
Simmons, Glenn Ashmore, and James Crombie. There was a real nice
drawing of knife-edge pivots done by James, but it seems it's no
longer on his site, but Glenn or Ned may still have it on their
harddrives. HTH
