I found some bent steel pipe, that i'd like to reshape into a bracket for a HID lantern :



So on the end with 2 bends i'd like to get one sharper bend and a longer straight section (instead of the other bend)
Pipe is 1 inch diameter, ~8ft long, 3mm wall thickness. I tried by sticking it into a hole in a concrete wall and pulling, it didnt move at all
How i bend this ?
