Directions for Spinning Ring


#1

I have seen several “Spinning Rings”. Several larger rings appear
spin on a central post. Does anyone have directions or know of a
books with directions.

Thank you all

At one point, many years ago, that design was copyrighted, I think.
But it’s also been knocked off by many others over the years. Books
are not likely to give you directions on how to copy something
someone else once made and copyrighted, but the basic mechanics of
the things are simple enough (another reason books are not likely to
dwell on them. They don’t represent any sort of technical skill or
advancement, just a design feature) The vertical central post is
generally a hard metal, either white gold, or stainless steel, often
threaded into the ring, perhaps riveted on the underside so it won’t
come out (or else just soldered in), and often threaded on top too,
for a top non-rotating cap of some sort. The spinners are made with a
socket that holds a small ball bearing, which fits down on the
vertical shaft. That bearing is why the spinning rings rotate so
freely around the post. The main thing is designing the spinner
rings so that the concentric rings don’t hit each other, and the
bearing is held securely enough. Usually it’s a small bezel like
affair with fold over prongs clamping the bearing in. Sometimes
they’re made so the bearings are thicker than the spinners, giving
clearance, and other times small washers are used to space the
spinners apart. Most of the ones you see on the market these days,
are rather cheap knockoffs, quickly made overseas. The main problem
in making these is finding a source for tiny enough ball bearings.
Ten years ago, or so, I had to repair these now and then, and got
replacement bearings when needed from C.R. Hill co in the Detroit
Area.
