Thank you again MikeCVH85 for the idea with the flat bar.
I used a 3mm thick alloy piece that I had laying around. Wrapping the stalk with a couple of layers of PVC tape helps protect the material.
Bending requires quite a bit of pressure against the flatbar. At the same time, you need to do it slowly and careful not to push it too far. It is important to really secure the vice tightly.
During the entire process I had to think about Arwyn. He is right - no special bending tool is required - but it scares the heck out of me if he can do this between thumb and fingers
