I am in the process of building a turntable made entirely of Delrin which I understand is as close to a metal as you can get in a polyvinyl product. Fabricators love it because it machines so well, and holds its shape under load. Enought that you can use it for a bearing surface without a sleeve. I hope to see what a turntable with a Delrin plinth and platter sound like compared to a similar ridgid deck.
However, a 3" thick piece of Delrin is about $250 per square foot. Dont want to make too many false cuts or holes in that.
