HF pipe bending dies

Can you not use the "follow along" approach? Bend a little, advance the work, bend a little more. Depending on the shape and the amount of room you have, it may not be necessary to do the whole 90 degrees between follow along operations. The only problem with bending only part of the angle and then going back later would be if the part work hardens too much during the process, but don't let that stop you from trying it out.

I do this with my Hossfeld bender.

This makes more sense if you're using a bender that holds the part rigidly at one end and then follows a die with a shoe around the bend, like a Hossfeld. The HF type pipe benders have 2 pins on the side and push a die between the pins. If you bent it some and then scooted it along a little then the pipe would be kittywampus. But it might work sort of.

Been a VERY long time since I heard anyone use the word kittywampus.

Kittywampus aside, you can usually bend a few degrees (ie 10 degrees on each side) beyond the 90 degree arc of the die. You will probably need to reset the roller followers as you approach the 90 degree point as well as add an extender to your ram. I would expect some gouge tool mark on the inside of the bend when it comes clear of the die. A couple pieces of 1" stock with the proper 'U' grove could be bolted to the end of the die on each side if that is a big issue.

Not that I have figured. I just bend 2 pieces and splice it together.
