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

["Thomas A Simmons" <tasimmons@west.raytheon.com>]

Hi Gil,

  I found your adaptation interesting.

  More than likely it's obvious, and I looked right at it, Your
web page description notes that one screw pushes against the ruler,
but (to me) it looks as if there is a bolt through the assembly
and a nut? Could you straighten me out?

  How does this assembly hold up with keeping collimination?

Tom
