A correction to the address for porcupine press: www.porcupinepress.com/_bending/TheoryAndDrawings.htm (not html and there is an underline (_) before bending that doesn't show up on the post. Also, the post about Ideal automatically inserted my sentence-ending period after .com in the address...
I found another site for conduit bending that may be helpful (full of theory, if your into it... but with a built-in calculator for the dirty work): www.porcupinepress.com/_bending/TheoryAndDrawings.html
Ideal benders has a great FREE conduit bending booklet, downloadable in pdf format at: www.idealindustries.com. It's under conduit benders in their product list.
