If it helps you guys - here's something about bending HARD lines that you might want to use...
Take your various size lines -- mark a start line - and bend a 90 and do the same for a 45 etc. Use these as templates transferring your bend start line to
your work piece.
It also took me awhile to figure out that you can actually measure where your bend is going to be and to set it up in the bender at the correct notch. Not sure what benders you're using - but mine have 0* R 45* marks on the tool as well as the RADIUS dimension that needs to be used (each tool bends a different radius).
Here is a really handy dandy RIGID instruction sheet showing various steps in making bends and how to use these tools. This happens to show their series 500 bender - but they're all generally used in the same manor. Hope it helps.
