I held off on placing the other bracing plates in the corners of station 1 as they were going to interfere with the plumber’s straps securing it to the jig. With it held in place the lower longerons were heated and bent upwards and inwards to the corners before being fishmouthed and tack welded. The upper tubes were cut to size and tacked too. Diagonals from the top of station 1 to the bottom of station 2 have been done now.
