Al-Paslow > This image shows a portion of the area where the diagonal was supported.
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 > 1958 Cave 10 inch f-7 Telescope photo
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!!!
