OK, hobbyist metal worker with no real specialist tools here.
I want to bend a strip of aluminium. I want to put four neat half circles i= n a strip! Probably something matching the size of the diameter of a coke c= an. The strip will probably be 40mm wide, 1000mm long and about 3-4mm thick= depending what I can get at the hardware store.
Would it be possible to put the bends in over a former, cold, without the s= trip bending?
