I did an 8" mirror tube a while back, piece of cake.
Went to a local sheet metal man, and he sold me the sheet alloy, from memory it was 1.3mm? thick, but there is varying thicknesses.
He rolled it to the diameter I wanted, while I waited/watched.
Cost was negligible, OK, not as cheap as a free off-cut of PVC, but reasonable.
I contact adhesive glued the butt overlap. The tube is effectively held by the mirror cell attachment screws as well as the glue join, and the front is the only "weak" link. Never experienced any problems at all. I baffled the inside though, front to rear, and these glued in baffles "may" have helped a little, not sure.
