using my gantry crane, a crescent wrench to bend flanges, and hammers, I've been working on getting the pillar back into shape. started by pulling with the crane while beating warped support metal back into shape, then reworking the flange into rough shape. made a shape template from the good side out of cardboard and used that to gage the appropriate curve, and will get the door put back on soon to gage from the inside.
got the good side cleaned up to make the shape gage,
pulled with the gantry crane and chain hoist,
roughly reshaped the flanges, (repeat step 2 and 3 a few times),
... and looks like we're close.
Keep in mind that there are two layers of sheet metal that will get welded back in. I'll get them clamped in place, remount the door, and check the door clearance before I start re-welding.
