I'll give the can lid/top a try. I might get some strange looks measuring can tops at the grocery store, but if I can find one 6 1/2 inches it might just work. Thing is though it has to be heavy enough to hold the copper ring along with the heavy (lead)? circular piece in place between the yoke and the convergence assembly. Are those pieces even really necessary? I have never seen them on any other roundie set, and also wonder what they are for. The heavy ring is held by the three stand offs with rubber pieces between. The stand offs go through the copper plate which was riveted on to the back side of the yoke cover. The heavy ring is not a magnet, as far as I can tell. It doesn't seem to be magnetic at all. Just a heavy ring. I wonder if I really need them. Oh, by the way there is a ground wire running to the copper ring.
