RE: ATM An adaptation of Gary Seronik's Curved Spider design.

Hey Tom
	I shouldn't speak for Gil but I had the same confusion until I
looked closely at the bottom two pictures. There are actually 3 screws/bolts
in his assembly not just two. One small one for controlling where the small
pipe fits inside the larger pipe, another bolt that attaches the large pipe
to the ruler(this is the bolt that he describes is longer than necessary and
touches the opposite side of the larger pipe). The third screw is actually
in between the other two and runs from one side of the pipe, out the other
and pushes against the ruler to move the assembly away from the ruler. The
last two pictures straightened me out.
