During the Kelowna Mountain Fire, back 20-ish years, I was in an aircraft repair and overhaul shop in Vernon BC, and the fella had a purely manual Diacro Press Brake there, about 18 inches capacity. Claimed he was planning on being buried with it, to spite some of his competition who coveted it. LOL!
I was fixing Bell 412's at the time and it seemed that life was entirely made up of dozens of little gussets and reinforcement pieces, for which, I though the little press Brake would serve VERY well! Particularly with the option of having several different die sets ready mounted. Eg: a straight die, a goose neck for doing tight corners, and a radius nose die to get a particular radius, all ready to use without having to tweak adjustments.
