Woke up way too early, fed the cat, had an idea for yet another way to approach making a secondary holder.
I was reviewing my collection of photos and builds of secondary holders yesterday, and grumbling and muttering because everyone else's secondaries are humungous compared to my dinky little one for the 4.5 inch scope I'm working, there's no SPACE for anything.
I was getting close to punting and just sticking it on a piece of brass that I could bend into place, and then try not to bend out of place accidentally.
Now I've got a two screw idea that I think will solve the two main problems (besides just being too small to exist) -- adjustability AND stay right there no matter what. And be buildable with my set of tools and materials. And be adjustable with allen wrenches. And not risk dropping said allen wrenches on the primary. I think. Build it and see. If I don't get yet another idea first.
