I made a very similar ring display a couple of years ago for my
outside shows after ‘losing’ a ring. My material list: 4 foot length
of 2 inch diameter PVC pipe, corresponding PVC pipe cap, 8 inch
plastic flower pot, cement, 14 inch square piece of plywood.
Sink the length of PVC pipe into the center of a cement filled
plastic flower pot. Attach the PVC pipe cap to the center of plywood
square with a screw (counter sink the screw). Drill evenly spaced 1/4
inch holes into the plywood.
Assembly & set up: To assemble - fit the cap onto the pipe. You may
need a rubber mallet to bang the top back off. Set up - Use a
loosely woven (read that cheap), round tablecloth long enough to
cover the hanging weights below the tabletop. Cut some metal tubing
into very short lengths to use as crimps, lead fishing weights and
fishing line work very well to secure the rings. Attach the weights
to lengths of fishing line & add a piece of tubing to the line.
Working from bottom of the table top; thread the fishing line up
through the hole, through the tablecloth, through the ring shank and
secure with the crimp (tubing).
Be sure to attach enough line for the rings to be tried on - about
an arm’s length. If the weights are heavy enough, when the ring is
put back down on the table it will reposition back into its original
spot. One older woman didn’t realize that the rings were secured in
place and literally jumped when the weighted ring ‘magically’ moved
back into its place on the table.
