Nice work, This is pretty much exactly what I was planing for my 109"

A couple of tips for you or anyone who wants to use one of these chinese pipe kinkers... I use one to do everything from bars, roll cages to custom "U" bolts

First off on your two rollers, they are kinking your pipe due to high pressure on a small contact point.... burn some weld either side of the contact point and grind and flap it smooth, turn them into rub blocks

Your dies need a bit of work if it is like mine the castings weren't strong enough or tight enough fitting so as you push for a bigger bend they allow the pipe to spread out at the center of the bend and your bend collapses or kinks.... this was an issue on my dies from Nom 32 up to beat this I clamped the dies in a big vice as tight as I could this closed them up a bit and then welded some scrap off cuts of 6-10mm plate on the bottom of them so they reinforced the die then I spent a free day with a bit of offcut pipe and the flapdisk polishing the inside of the die so the pipe fitted nice and snug
Since then I've never had a bend fail scrutineering for competition

Contrary to what everyone says you can bend tube in these benders, what you need to do is make a sock that fits into the die out of a piece of pipe... I think for the 25mm tube I used a bit of either sch80 Nom 25 or Nom 25 heavy wall... bend it in the die and then cut the bend in half so it leaves you a sock that fits inside the die... with this trick I have bent 25mm tube to 90degrees without any collapse
To find your size of pipe to make a sock you want it to be a bit of a force fit to fit the tube inside (remember you have a seam on some pipe and this will bugger it up a bit, also your dies and rollers need to be done or you kink the tube)

Hope this helps out
