Mirror cell open, and in place on the back.

The mirror cell is a hybrid three point suspension. From star tests (on the finished telescope), this mirror cell has worked very well. It consists of three groups of the following: double sided sticky tape, a 3 1/2" ring of 1/2" plywood with a hole countersunk in it, and a 2 1/2" X 1/4" countersunk screw. Each bolt has a 1 1/4" spring that (as a guess) pushes with about 10 lbs force, a washer and a nut that can be turned by hand. The holes through the 3 1/2" ring should be a bit loose, so kind of wiggle the drill around in the hole. Be sure to then create the countersunk hole for the screw head, making the screw flush with the top of the wood.
