I would do the same if a workshop was nearby. Most of my working life I have to improvise, as we are tide dependent for access on and off with a boat. And my home is a village with no workshops for a few miles. I like DIY solutions when I can.Whenever I need something bent (folded) (3 or 4 mm aluminum, 3 mm stainless, or 4, 6, or 10 mm mild steel), I always go to my local metalworking shop. They have the material I need, and they have a 200-ton press brake with which they can bend or fold the workpieces according to my specifications.
