Frame repair questions

I posted this in the CJ forum, and figured I'd post it here for some other points of view. Forgive the double post.

I figure I'd throw this out for suggestions before I get to the point of no return.

Here's my plan. I cut out the bad part at the spring hanger, and made a patch piece from a hunk of box tubing, 1/8" thick. I want to keep the outer rails looking nice and smooth, if at all possible.
I plan on welding in the piece, then cutting out the inner rail to repair it. I have thinner wall tubing to make a piece for the inner rail.
Once I cut the inner rail open, I plan on fish plating the outer rail from the INSIDE.
The green was my plan, the yellow at the top if needed.



I can then close up the inner rail, and fish plate that, if it's needed (?). I can then grind the outer rail smooth, if it will be strong enough.

I've never done more than slap on some patches, so I'm turning to the guys that have done it before. I want to do it right, and not have to second guess myself.
This is just a rough fit.






Am I on the right track????

You might want to throw in some inner frame gussets before the plates

Not a bad idea. The cage tie in will be in that area also. I plan on fish playing the inside with 1/4 where the tie ins will be once I figure all of that out.

That should work fine. Just be sure to get full penetration with the weld.. so you don't have any "thin" areas when you grind the welds down.

Thanks Eddie. I'm thinking of just welding this piece in enough to hold everything in place, doing the fish plate on th inside, then finishing the welding. That way the seam gets welded to the fishplates behind it also.

Once I started welding I couldn't stop. Went ahead and welded it completely in and ground the welds down.
Now I can cut out the inner rail, weld the seam on the outer rail from the back side also (if there's any spots lacking full penetration), and fish plate it from the inside.

I went down to the metal supply and got a piece of 4x2 rectangle box tubing for my frame. mine is rusted at the shackle and I figure I need to replace the entire frame from 4-5" fwd of the shackle mount, and then go to the rear of the frame at the rear bumper.


I was thinking of taking the piece of metal I have and have a local machine shop put a bend in it so that I don't have to weld a bunch of pieces together.

Has anyone else done this?
