this is a closeup taken a year ago in the snow the day the gates were loaded for their trip to Miami

I need some advice on forming channel.  Hawke Industries claims that thier tube bender can form channel for gate arches and I'm wondering if it's possible.  I'm looking to purchace a tool that does this and with what I consider as a full search on this matter I only seem to have found this one tool.  I've formed channel in the past on an old power roll former at my last iron works job and it was a pain because the channels would collapse.  So I would roll so far and with a couple tools I made would work the legs and web as straight as I could and then repeat the process.  Has anyone had any experience with this Hawke Tube Bender.

This is a newly finished commissioned gate for one the gardens of some dear friends.
It forms a protective amulet for their bees,and the other butterflies and hummingbirds that are attracted to their strategic plantings.

On my way back from Miami ....fixed all the boundary railings and tested a gate in place ...next visit for the stairs and lights
