Maybe set up a jig with plywood & dowel rod
Fairly rough first draft but i would say brake line is a possibility. I think the arch for the middle should be more gradual and the arches at the bottom tighter. You may notice the one side is an actual bend. Yeah i got lazy and didnt use the bender for the other side. Thought process is the holes drilled through the top would be used to nail it to a 2X4 or some type of pole to line them up. Thoughts and suggestions welcome.

I got food to eat and grass to cut. Play time over.
