I got the wire frame welded together. It's pieced together from odds and ends. The frame will be covered by roofing rubber (45mil EDPM) so the frames doesn't have to be pretty. I have a little clean up to do on it to smooth out of of the rough edges that might tear at the rubber. I'm hoping I can find time this weekend to cut and attach the rubber. I'll post pics of the final results with closeups of how its attached. My plan is to use an arrangement of clamps to hold the rubber down with out having to use adhesives.
EDIT: apparently the images either didn't work or I'm impatient. If the images do not show up heres the links to the pics of the wire frame on the bed.
