I could do that, but it is a PITA and it would not look nearly so nice. It is a lead-filled NS tube bent over a mandrel in a spiral, then slit down one side, creating a bunch of separate loops that have offset ends (from the spiral). They are then bent to be almost joined at the ends, and then the lead is melted out. They are placed on the mandrel again and tapped closed. A hole is drilled through and a threaded post is inserted. All of that is brazed over to make it very strong. Then the joint and post's contact points with the tube are filed or sanded until smooth.
If I could locate the correct OD NS tubing I might make a batch of these. But I would probably have to waste one tube for practice. I have the right size of tool steel rod to use as a mending mandrel.
Willson rings have an excellent added step that I would incorporate into any rings I might make. He cuts the tube bottom flat and brazes it to a nickel silver disc. The threaded post is brazed into the disc. This is probably a good bit stronger.
Maybe I need to make and sell these? I would have to have the female sockets machined for me, though.
What a PITA…
SOMEONE SELL ME YOUR WILLSON THUMB RING!
These two pics are of @Sousaswag's Willson thumb ring. Mine, shown above, did not have this baseplate disc. I simply patched the huge hold left when I shaved off the flat base of my ring, drilled out a tapping hole for a threaded .25" rod, screwed the rod in, and brazed both ends. (I did not get Sousaswag's permission to use these photos, but I am pretty sure he won't care.)
