Al-Paslow > I placed the cotton into a plastic bag to keep dirst & moisture out. Will I reuse the cotton? Well...if I get a better idea no, but if I do use cotton, this original material will simply be reassembled.

Al-Paslow > Aother closeup of the Cotton within the cupport. Another thing to notice, that CAVE like Ken NOVAK, both use similuar spider designs. (Although I don not believe NOVAK used cotton as a mirror support!) The cylinder has a beveled edge that the diagonal mirror fits into from inside; hence it supports the optic by the mirrors face to an extent. Actually this rim or bevel runs the entire circumference of the ellipse, and adds a tiny amount of obstruction to the entire system.
Al-Paslow > Wow...Upon removal of the diagonal and housing assembly I soon found out what was holding the original diagonal......a really big pile of COTTON!!!
