Hey everyone, I need some help selecting materials. My American Government teacher approached me with a project to build. He is a drummer in a band, and needs "drum risers" made, but they need to fold, and it has to be lightweight. It needs to be 6' by 8' by 8"tall.

So since the risers need to be light, I figure aluminum would do the job, and also be strong. If any other opinions please let me know.

Now for the frame, what would be good to use? And also what thickness should the material be?

Any help would be great.
Thanks in advance,
