I contacted the company. It will do the job but the mandrel with the correct former will cost £600.... EEEEEK !!!
Well, I do a lot of Round the World travel. I'm a Technican for a BMW main dealer but my main interest is 80's, 90's single cylinder Enduro bikes. For this project, I want to build a rear carrier for a pelican luggage case and some side rails for Soft bags.
Without ever have used a madrel, bender etc, I have no idea what I'm looking for... It's very frustrating.
What bend radius do you want? The bend rad is usually described as Centre Line Radius (CLR) in terms of diameter, so a 3D CLR former for 18mm tube will make a bend with a 54mm radius to the middle of the tube, 45mm to the inside of the bend, and 63 to the outside. I've bent 1/2" schedule 40 pipe in my hand bender on a 3D die, it has a wall ~2.5mm thick, and is bigger diameter ~22mm, so 18 x 2.5 is doable, and shouldn't need a mandrel to hold its shape.
A cheap pipe /conduit bender (record /hilmor) will be fine if you have proper dies, which aren't all that expensive to make. The follower is the more difficult of the two ( for me at least). I made dies and followers for a Record plumbers bender to do tube work on bike frames, I've bent from 7/8" to 1 1/4" in various wall thicknesses with good results, but I did need to reinforce the handle. Depending on what bend rad you need, and how much of a hurry you're in I could likely make you a die set, and for a lot less than £600. Drop me a PM if you're interested.
