So this sounds stupid, but I'm sure someone has had to deal with this at some point and I am looking for some advice. I have an old Edmund Scientific Rank refractor and the original thumb screw that holds the eyepiece in has stripped out finally. Is there such a thing that clamps around the outer diameter of the focuser tube that replaces the need to use the tiny screw hole? Specifically one that has a brass compression ring or even better that has a self centering mechanism? I bought a couple different items and they aren't quite what I am looking for. They are extension tubes from svbony with compression rings. I had the thought of welding one of these extension tubes to the focuser tube... but that isn't something I want to do to this scope.
The outside diameter is 1.365 in or 34.65 mm
