First tubes are bent, profiled, and offered up to the headstock and rear axle flanges. Alignment of tubes was done using 2" x 3" lumber which was drilled in pairs which were bolted together at their centers with a 1/2" bolt. One inch holes were drilled through the parting line, and the two halves were then bolted to the fixture and spaced the lower tubes at their proper height and width. Similar pairs of 2" x 2" lumber was used to make clamps to support the suspended ends.
