What type tool you have for bending 90 degrees ?

Thank you Paul. I will do try something out of it.
Do not you still have another easy way for to solve this first operation?

There is always this https://www.youtube.com/watch?v=4Z4PDLN9XKE

Looks like he made it from a pneumatic sheet metal nibbler? have seen air op door skinning tools that work with an air hammer that may work for flanging.

If I do not know, I'll ask twice.
I can see from the video that it bent pretty well. Congratulation. Is it a profile C and a pneumatic cylinder? It is so?

Doing a door open is normally a key, I do not know. Are you doing pneumatically?

Here's the trumpf

Its a complicated piece with moving parts, be hard to duplicate.

From the right of the picture, the sheet would be clamped to a moving arm or a circle fixture. The arm is like the fixture stop in a pullmax, sets the distance from the die, in the Trumpf the metal is clamped to the arm and the whole arm moves in a carriage.
