One problem with yesterday's design was that the frame jutted out immediately below the bottom cone, so anything hanging there would rest on the copper wire. I considered reshaping the wire so it approached from the bottom with a long stem but discovered I had some brass coupler nuts. I formed a new frame and soldered the nuts to the ends. During the process, I held the nuts on a threaded rod to ensure they were in a straight line.

I installed nylon nuts with divots in the ends through the coupler nuts. The copper wire provided a bit of elasticity to hold a spinner securely. When I was happy with the frame, I made a copper spring. I had a nylon spacer with the correct diameter, so I wrapped the wire around it and soldered the spring to my frame. The spring bounced in every direction and interfered with the spinner, even without a weight at the bottom. My next attempt will be using a short spring made from flat brass, and I will use a heavy weight.
