Then we will wrap copper wire around that edge. Turning this disc into an electromagnet. He made a few different size metal blocks. I'll use them to hold wood together after glue is applied. Turn it on and see if magnetism hold everything together as the glue dries. It will either be a heavy desk weight or a great jigging device.
I'm having a little trouble envisioning this. What will you use it for?
