As far as the support material, I would suggest Delrin (Acetal). You can buy scrap pieces on ebay and they machine really well.
I'll check that out. I think that's a hard plastic though. I'm thinking material just like Rob uses for spacer. It looks just like 3/4" horse stall matting to me; which is what I am considering for prototype. Better cushion. I'm going to swipe a small piece from my daughters mare and see how it tools.
