[Atmswap] 8" flex mirror kit

[DAVID RATHBONE]

Anyone interested in an 8" flex mirror kit?  I got permission from Alan 
Adler to put some together.  I can get some things cheaper if I buy in 
quantity.  If I can get at least 6 people who want to buy one, I will put 
the kits together and ship them.   The kits would consist of the following 
items:

1 - 8" blank, 0.8" thick (10:1 ratio)
1 - Sponge rubber puller cushion material, 12" x 12" x 3/8" thick
1 - Sponge rubber pusher material, 6 foot length
1 - Rubber pusher material, 3 foot length
1 - Polycarbonate sheet for the puller plate, 12" x 12" x 1/2" thick
1 - Polycarbonate sheet for the collimation plate, 12" x 12" x 1/2" thick
1 - Two part adhesive kit (enough for several 8" flex mirrors)
1 - Puller bolt and washer
1 - Tension spring
1 - Tension adjustment knob
3 - Collimation screws with threaded inserts
3 - Collimation springs

This includes parts for an upgrade version of the flex mirror as it was 
presented in the Sky & Telescope article (Nov., 2000).   I will include 
instructions for this update.  The tension spring will assume an f/6 mirror. 
  Of coarse this can vary somewhat, but anything far from an f/6 would 
necessitate a different tension spring.

The price will be $170 for Pyrex and $155 for plate glass, plus shipping.
