What kind of bender does this?

admin

This is 7/8" stainless tubing on a boat, what kind of bender do they use to make these bends so close together?

Reply:rogue mfg bender will make back to back bends.  https://www.roguefab.com/product-category/m600mandrel/
Reply:Without looking at the links, when I first read the question..........................any draw bender with a setup for mandrels will do this.Then I looked at the links................confirmed my thoughts.I built a draw bender, and will someday set it up for mandrel bending when I need to.  Which might be never.............I'm on the downhill side of 70yrs old.

..........but that's why you own machine tools I guess)

Reply:Depending on the wall thickness of the tubing you may be able to make these bends using standard hand benders. Thinner walls may require internal support to bend without wrinkles. I have an Imperial 600F worm drive bender that will do up to 3/4" diameter. I made a video that shows how to use it and how I made a custom die for tighter radius for a project I was working on. I needed to make a 180 degree bend followed by a 90.

One plus it that I don't have to worry about leaving marks on the tubing.Thinking about it... your assessment of aluminum may be unfounded. My Greenlee conduit bender uses aluminum dies and will bend EMT and rigid pipe up to 2".
