    Is 1.5" tubing enough for a cage if you triangulate all the corners. Also, what pipe bender do you guys recommend, it will only be for my own use and I don't wan't to spend a bunch of money on it.

    1.5" TUBING is fine

    Bending it with a "PIPE" bender is NOT!

    Pipe is for plumbing, conduit is for elecrical, and tube is for structural. I think 1.5" tube is a bit on the small side for a fullsize cage. It is fine for support, and gussets, but the main structure should be something bigger.

    As for benders, look at an M-Tech or JD2 (same design). There are plenty of benders to choose from. A complete tubing bender will set you back over $500 to start bending one size of tubing.

    Also a roll cage is the worst project for a beginner fabricator.

    wall thickness is also an issue. Most guys that use 1.5" tube on buggies and such are using .120 wall. If you ran .134 or .188, or made a cage that was like a jungle-gym of tube, you'd prolly be fine. It also makes a difference whether its DOM or not. Someone over on pirate posted a little graph showing the relative strength of various sizes of tube, and hrew vs dom. DOM definitely had an advantage. Anyway, I'm gonna make mine out of 1.75 x .120. Prolly hrew cause I'm cheap... prolly a jungle gym because I actually like the look. ;)

    Pipe is defined by it's inside diameter (and it's schedule)

    Tube is defined by it's outside diameter and it's wall thickness.

    1.5" pipe (sched 40) is 1.90" outside for example, 1.5" Tubing is 1.5" outside.
