	Does anyone out there know of an electromagnetic device that is capable 
of producing large amounts of force (>200 ft. lbs.) within a high amount of
accuracy (+-.001 in.).  I know that this may not be possible but that's what
makes this project oh so much fun.

	Also I heard that peizo-electric crystals are capable of fairly amazing 
feats like this.  Can someone with any knowledge of these please post or Email
me.  Thank You in advance.
