For a no welding all-aluminium solution:

I built a plennum chamber by building a frame from 20mm x 20mm x 
3mm Alum. angle (L), I mitred the ends of the frame and used sheet 
alum. bolted to the frame (tapped holes in the frame) to both hold 
the frame together, and provide the walls. Whatever else you do you 
need to make sure it wont rip apart under 25"+ of vaccum. Internal 
bracing with 3/8" dowels is one idea that worked for me. It still 
flexs quite a bit.
