    I had a thick piece of aluminum, cut square and nip off the corners, chucked up in a mandrel I had made.

    Make a circle, in this instance size doesnt matter, it has to be large enough to be usable on a 400 day clock, this one is 3 3/4 inch diameter

    Would have been quicker to use a thinner pieces, I ended up just over a 1/8 inch thick, dont think you want it much thicker as it will hit the pendulum balls, faced off both faces and knurled the edge, use you imagination in design.
