An afterthought. Depending how much $$ you want to put into it, and how much weight the "fragile factor" has, perhaps a piece of polished stainless steel or chromed steel? That may be a good idea. Someone else can do it though. I'm happy with the performance of the plexiglass AH. It suits my purposes. Just for future referance plexiglass comes in sheet thicknesses up to 2 inches that I'm aware of. We use it on many shipboard applications.All the way from 1/32 in thick clear sheets for chart table coverings to 3/4 in thick clear and smoked for portholes or windows.We always have sheets of 1 in thick p.g. in one of the lockers for emergency use on board.

The stuff isn't THAT limber, is it? Bruce, Plexiglass at 3/8 in thick is NOT limber. Especially at an 8 in diam piece. I mean if someone would stand on it or grab the edges and flexed it it would bend etc. It's more durable/less fragile than is glass. There are trade offs in useing it though. One is it isn't quite as reflective as glass.Another is it scratches/blemishes easier.
