View Full Version : Metal torsion box construction question

10-15-2005, 01:31 AM
Hey guys!
I'm hoping someone here has some experience with this. I've monkeyed around with it years ago doing wood work and even talked some engineers at a R+D (job I had for awhile) into using it on a problematic mount for a grain header mount on a harvester. Ha...It worked fine but I was just guessing.
What I want to do is build a super lightweight crossmember for a 4wld truck.
It'll mount the tranny/t-case.
I have it figured out how to build it but ?I'm not sure what thickness of materials etc to use.

You're bending & welding it out of steel sheet? A good starting place would be to look at similar existing mounts on 4WD trucks - the manufacturers probably aren't wasting too much metal on making them overstrong, and yet they're likely to be doing the job.
