I really dislike most finder mounts - I understand the need for adjustment, but both common types (a flexible but fixed end with a 3-screw adjustment side) - and the ones with the 3-screw spider on both ends. Some have one spring plunger, and others don't. I just never have liked them.
I like the split-ring style like a typical guide scope mount. I also use arca swiss mounting plates for most of my camera stuff and I find them to be pretty repeatable. So I set out to make a plate that would be mounted to the scope with a dovetail and an upside-down arca swiss clamp holding the ring mount.
The machining part is pretty easy at this point ... the only real challenge for manual machines is making the curved underside of the mounting block to match the OD scope diameter - but even that was just time consuming but not too hard. What I am more excited about is the anodizing. I made it from aluminum and I am just getting into anodizing. I picked blue for what is probably obvious reasons. I'm really happy at how the anodizing came out. In past attempts I've bead blasted the surface, which gave a poor result. This time I polished it to 320 grit before my anodizing. I like the finish so much better.
Just sharing ... not taking orders HA!
