There's a good article at www.electrician.com in Articles 1. I would have done the link right to it but wanted you to check out the rest of the stuff. Otherwise, just use the cosecant of the angle you want to bend.

Ralpha494, Your link is from Gerald Newton's site. Did you know that he started his form up again after a bout with being SPAMed? Mater of fact the very latest post of his was about conduit bending. I'm not a conduit guru that has the experience to answer his question but maybe one of you guys can. The subject is: "Opinion about the Benfield Conduit Bending Manual by Jack Benfield - Gerald Newton 23/PST Tuesday/January/24/06 (0)" It's another good place to hang out. http://electrician2.com/elwwwboard/wwwboard.html

The multiplier method, even if not perfect, is fine for small conduit or stuff thats hidden. You can usually get it close enough to make it work. If you have to be acurate, the best way to bend offsets is to field bend it. Field bending is described in a some books. I have an Uglys book and it is described under "Chicago Type Bender Off-Sets" This method can be used for foot benders and hydraulic ones.
