I have a possible new project - welding fixture for HF-welder.

Overall the fixture is quite basic except for the brass electrode.
Electrode profile dimensions 30x6,5mm. Overall fixture size is 900x700mm

I have not seen this fixture in real life, but common sense would be to bend it from a bar stock. But considering it has to have quite tight tolerances and 2 identical top and bottom contour - this makes it extremely difficult. Though I do not have any experience with brass bending...
Surely it is not milled out from solid?! :D

What do you think guys? How it`s made?
