Should you have the same or similar experience to me.
To de-banana a steel flange:
You will need
- Gaffer tape
- Thin steel sheet cut to size for the jaws of your Stilson wrench (a sliding jaw parallel wrench could be better)
- Stilson wrench
- Hammer (optional)
- Anvil (optional)
- Support for the slider to being it level with anvil

Tape the area to be remediated. I used 3 wraps total.

Cut some thin steel sheet to size for your Stilson wrench, make a nice crisp fold so it can get right in there.

Using your Stilson tease the flange back to position, only do this a few degrees at a time and move down the length of the flange as you work. Start at the position which has the most deflection. Make sure to tighten the jaws so they're snug, as they will work lose.

After teasing back into the original shape by the Stilson wrench you may need to gently tap the flange with a lump hammer to flatten it out. Make sure to hold the hammer parallel to the work piece to avoid damage. 3 or 4 extra wraps of gaffer tape will provide adequate protection. Note you dont need to hit too hard, just tap things back to shape.
After doing this you should be good to go.
