Hi all - I built from customer's plans a storage container, which is thankfully now completed and delivered.
Specs:
10" diameter x 27" tall cylindrical container, with an easily removable, gasketed lid
welded handle constructed from miter-cut tubing (6061, .065" thick, 5/8" OD)
5052 aluminum main barrel (.065" thick) and end plates (.080" thick)
TIG welded with a rock-solid reliable, 3 year old Everlast Super200P and 3/64" 5356 filler rod
The completed barrel is so strong, with it laid down sideways on the floor, I could stand on the open end without it deforming at all. (The lid would still make a perfect fit afterwards.) That said, the thick, strong barrel was a *real PITA* to form into a cylinder!
