Fino's 1970 Cj5 Build Thread

I know overhead welding is hard but I would be tempted to add a gusset or strap band under the tubing too.

yup....I am still figuring out the details of this, but I do want to add some strength connecting across under the bottom of the tubing

It'll be fine. Weld it up, probably stronger than factory.

Weld up the round tube everywhere and call it good.
No need for additional.

Weld it. VERY strong looking! Nice job.

So the round tubing is 1/8 wall....it makes me a bit nervous.....you still good knowing it's 1/8 and not 3/16 (it's what I could get)? That front x member has a flat plate welded across as a sort of base plate under the upside-down U-shaped channel piece. I assume that is OEM and not a PO mod for strength....that plate is now welded to the tubing along both edges (the tubing is also welded all the way around both ends to the sides of x member), so the bottom arc 1/8 wall tubing sort of replaces that flat plate which was typical jeep frame thickness of a little more than 1/8. One thing going for me is there is a front rectangular tubing cross member right at the front of the frame horns that chuck put in when helping me repair those. I would think That reduces the amount of flex on the frame and helps protect the crossmember under the radiator (the one I just cut the pass through).

I think you’re fine. The tube itself if offering an immense amount of strength. Add to that a circumferential weld will make it bullet proof—even at 1/8” .
