ok i had someone tell me that a drilled straight axle is stronger then a solid one he said it lets it flex but that doesn't make sense aren't solid axles designed to flex anyway???
I figure that if they were better, Henry Ford would have made holes, just to save on material costs. You know, 2 cents and axle back then would have been a pretty big deal, if you are making enough axles.

If I remember right when Pete & Jakes introduce their aluminum I beam they did some testing and found the drilled axle was as strong as the undrilled. I can't remember which magazine the article was in.
