For any of you out there with an old Orion UK scope. I wanted to make some Wilcox Rotating rings, but with the old Orion tube rings being so thin (I mean thin between inner and outer surfaces) if I built conventional rotation rings made of some sort of flexible plastic pipe with a Jubilee clip inside, when you slacken the tube rings off the front one would ride under the curve of the rotation ring.
So to get round this, I had to find something made of hard plastic, so as not to bind with the tube ring when rotating and it also has to have some depth but be square and not cylindrical, and be pliable enough to bend round the tube.
I found the answer in electrical wire boxing. I used the front part that slides over the part you stick to a wall, outside against the tube. Not only is this perfect for depth so the loosened tube ring dose not slip over the top when rotating, it has the added feature of allowing the Jubilee clip to seat it’s self in the recess of the plastic boxing. It works wonderfully well.
