Here's the unfinished secondary, and next to it is a newt diagonal from my '79 Cave 8" f/7 I have
adapted to fit the secondary holder. I made new screws with hex heads because the hub will not
allow a screwdriver in to adjust these. And I made the 3/4" shaft for the hole in the hub.
Both of these have a 3/4" shaft you plug into the secondary hub and tighten a set screw.
The newt diagonal is 2", too big for my Cave anyway.
I have a feeling the Cass/Newt was intended, and actually The Professor mentioned it. I'm only
using existing holes and not modifying any of the original structure.
Eventually I will need to read up on figuring and testing a convex Hyperbolic, that should be
interesting because that's a place I've never been and they don't accept American Express!
