I have a customer who wants a 6 ft by 6 ft round sign (2 sided), that is "dimensionally stable", in other words, it will be supported at the bottom only - nothing at the edges or top. I'm wondering what type of substrate to use. It's the six by six that's throwing me - does anyone know of anything I can use that is made in that larger size? There are horizontal lines at 2 ft and 4 ft from the bottom that would be ideal for covering up a splice, so I could conceivably make it from two pieces of alumalite, with a splice 4 ft from the bottom. Any hints or suggestions out there? PS- this sign will be all vinyl - both cut and prints.

I can see how the "bottom support only" aspect could make the splices pretty un-desirable, but you could possibly have a structural center piece that is 6 feet tall, but only 4' or less in width, that have 2 circular sign faces sandwiched on both sides of the central structural support. Then your faces could be something lightweight.

It may be impossible for this application, but I have seen backlit faces made of a "flex-face" material. It must be pretty tough to last that well. I've never used it, know little about it. I think it's stretched over a frame. The round shape might make that method impossible.
It's times like this that the skill of welding is handy. If I was making a sign with a seam in it, I would certainly have one of the horizontal support/mounting bars right behind the seam, so that both pieces of substrate could be fastened to the same bar, thus holding them "down" together.
