Another great idea Dave! Thank You! Got the hinges welded on and "blind welded" the bottom flange, which worked great. Drilled 3/8" holes 4" apart and welded from the inside. After cutting out the rest of the door, it would only lift up about 1/4 of the way before binding. The pipe had expanded almost 1/4" over the 41" opening, so the two middle hinges were higher and binding on that 5/8" rod. So I pounded out the rod and I'm going to make the holes in the two middle hinges more oval. Then use short 5/8" bolts and washers on all 4 hinges instead of the rod.That will allow the two inside hinges to open without binding and the washers will cover the enlarged holes. The two outside hinges will remain snug to keep the door corners tight agains the CC, which for the most part are still lined up all around despite the expansion.
