Before and after flattening

Segment No. 1 is back from the machine shop. The result was not as successful as the flattening of segment No. 2, but it is much better than before.

Segment 1 (joint 2-2) before flattening in a machine press. There is far too much strain in the steel. The bolts are removed to show the warp..

Segment 1 after several passes in the machine press. The plate is much flatter, but there is still some strain.
