Ok, that image, and your description cleared it up for me. See, the reason i thought it was "booty-fab" was because i thought they were simply weakening the metal by grinding it, heating it up, and then forcing the entire axle tube to twist. Now i see that they are twisting just a small portion of the tube, one that is completely free of the rest of the axle tube. My thoughts were that they would be weakening the axle tube by heating it so much that they could freely bend it.

I understand better now. Thank you. <img src="/forums/images/graemlins/cheers.gif" alt="" />
