I have a guy locally that can weld aluminum for me. I'll probably go for 2" square tube for a beefier look. It just won't finish as well as wood with the welds. I have 2x4 mounts built into the stand already, so mounting the arms is taken care of.
I would hang it from the ceiling, but I have set the tank up in a temp location before I move it into position and I don't want to suspend it twice.
