what now?
I've managed to return the fold/corner to its original position by stretching the weld. Now most of the patched area is low. Logic tells me that this needs to be shrunk to raise this area up, but shrinking from the welding process is what I just recovered from. Help!

I know others would do it differently, but on thick sheet like this I would now hammer up from underneath with the dolly on top along the HAZ to lift it up some more.

If you can knock it upwards from inside, then raise the lows with a crowned dolly and flipper

Jeff,
Just make sure you have a smooth weld on that back face(underside) you may have to get in there and grind that weld bead down, then try what Marcus and Martin suggested to knock it up from the underside. If you have a weld bead, that's not the same thickness of the material your trying to move, it will cause you grief and be very hard for you to try and stretch it. Remember to grind only the bead and not surrounding metal, I see this a lot, where guys grind the weld bead and joining metal, you end up with spots that thin, it was pointless putting new metal in there in the 1st place. Keep it at Mate! your doing a fine job so far.

Bump up the area - although am I seeing a bend in the shape where you show the straightedge meeting the bed side?
If so - Ford F100 beds for instance have a bend like this at the top of the two long sides. I use a "cocking tool" to cock that bend, using a 16oz ball pein and a blunt carpet chisel. I move back and forth along the low area of the bend, striking the chisel to gradually bring the bend into alignment. I think "gradual" is a key word for doing any bed side.

This is nothing but confusing …… there is 2 different threads running on the same panel at the same time !!! One of the narrators should combine the 2 into 1. ~ John Buchtenkirch

I'm sorry, I was convinced, and still am, that there are 2 issues here. I have a hard time seeing how welding off one corner could have an effect along the whole length of an 8' panel. Especially now that I've stretched the welds and returned the folded edge to its original location.

Jeff, just for grins, move that straight edge up on top of the "tube" and see if that isn't low as well. Back when these trucks were used as trucks, daily use put in quite a few dents and dings. From here (on my monitor) it appears as if the tube is low as if someone dropped something on it many moons ago. If that is indeed the case, it is affecting the flat area as well.

It does make it confusing with 2 threads for the same job, but in Jeff's 1st thread, he's only asking what happens if you shrink the centre of a panel. Then he has just used his repair as reference. I think he is more concerned whether the welding he has done in fact,has made it worse than what it appears to be.? which is a problem when you do something with-out 1st going over the complete job for prior damage or distortion.

It still looks tight along the weld, you need more stretching along the edge of the weld. You need to get more metal for that corner to move, and the only place you will get is from that area, and maybe from the lower section from that patch you put in.
