I've got a question for the Doc or anyone that knows i guess.
I built me a bit of a roll cage out of some kind of rod for airplanes. The cage works great and is fairly well indestructable. My problem is mounting it to the chassis. The rods are so strong it takes like 2 dremel blades to make one cut or it takes me a fair bit of effort to cut with bolt cutters (and I'm no small guy). BUT what i was planning to do was to bend about 1/2" on the ends and flattening the bent part to drill a hole to screw them to the chassis. The problem is, anything more thana 30 degree bend or so breaks them. Just too brittle. I ended up bending copper batterycable ends and soldering them on but damn is it ugly and the solder is prolly the weak point. Also, this type of rod is VERY hard to weld. I tried arc and mig with argon. The mig did it but not too nicely.

SO, after that boring monologue...

Can anyone reccomend some sort of rods or something that I can use for this purpose that I can bend and weld easier? or suggest a nicer looking way of securing the rods I have?

Thanks
