Success -

Well, I've been able to make the filter rings I need. Thanks to JY and Jim for the suggestions.

I had a bunch of rings in different sizes already from my MF and digital lenses (mostly Cokin and Lee). I found that a 52mm ring is 3-4mm to large for the OD of the Goerz 9 1/2 lens I chose 1st. I had some 2mm thick cork sheets laying around from when I made some header gaskets a while ago. AutoZone - a few bucks. Anyway, I crazy glued a piece around the inside of the ring, let it dry, then glued another inside that one. When it dried I shaved th excess with an Xacto and it fits "perfectly" around the outside of the lens. The cork will not mare the finish and it stays on and also comes off easy.

Tested all day today, works like a charm.

No reason to spend $60.
