did you sell the axles? i love that exo-cage. i like the way it protects everything and also i love the way it ties into the ''bed''(looks like you put alot of thought into it), i'd like to see it from every angle you have of it...i may build 1 identical or real close...i like it THAT much!(you didn't happen to draw up blueprints or saved a CAD print of it, did you?)
i noticed some1 made the comment that it was pipe, are we talking about sch40 or sch20 carbon steel pipe? if so, no wonder you breaking 1 ton stuff, did you ever weigh it? if thats sch40 pipe, it would of weighed in like a tank, but you wasn't going to hurt it! i bet if someone was to fab that up w/ 1 3/4'' .134 wall dom it wouldn't tear up 1 ton axles....not nearly as bad anyway.
what diameter pipe is it? did you use weld on bends & grind the weld down smooth to make your curves or did you bend sch40 or sch20 pipe? what did you use to bend that heavy of pipe? sch 40 pipe prolly has a heavy enough wall, you could bend it w/1 of those bottle jack benders, they call ''kinkers'' w/o it kinking. if you could get pins that would hold up. sch20 prolly not heavy enuff not to kink, its only 1/8''(.125) wall. sch40 is 1/4'' wall.(.250) that would be HEAVY!
