I have to make a fair number of 5' x 5' aluminum frames out of 1" by 1/8"
6061 aluminum bar stock.Each frame is subdivided by additional aluminum pieces into a grid of 12 by
12 squares.I am looking for the best approach and/or jig to keep this large but thin (1" depth) frame from either warping out of its plane or not staying square.
How is this best approached, I intend to tig weld all the outside joints and some of the interlocking pieces.
