cages

[rip]

I've heard of people making their own roll cages, but it seems like they'd be weaker than one built for you, right? I mean shops go out and spend $$$ for these high tech tools to make bends and weld it all cleanly together.

Well I guess the question is has anyone made a cage and still turn out really nice?

The ones I've seen were made from the pipe benders at like harbor frieght and mig welded, is this even legal in some classes, or is it more so the construction and materials?

thanks
