How to straighten panel

The panel looks worse than what it is after putting a 2x4 along side it. I would still like to know how to straighten it. This is a header panel for a 67-72 wood box. I need to cut out all the rust which is where the wood lays on the lip, but before I do that I feel that it's best to straighten it all out before I cut and reweld.

Thanks

Re: How to straighten panel

Here is where the dent is which pulled the back part of the panel towards the dent. Hope that makes sense? I know I have to remove the dent, just not sure that that would solve the issue.

Re: How to straighten panel

Hopefully you can tell where the dent is that I'm looking at and where the panel is bent. Like I said it looks worse than what the 2x4 is showing which is a little strange. I just would like it to be as straight as I can get it so when it's next to the cab it looks good!

Re: How to straighten panel

Round pipe or solid steel rod that is snug inside the hole, and drive it past the dent to bring it up. Or perhaps some all thread and opposing inserts that have sloped ends that will force each other outward as the all thread is tightened. Not sure how thick the metal is, but perhaps a dent puller using welded on studs, or welded on washer as anchor...

Re: How to straighten panel

i really wouldnt trust a 2x4 for a straight edge...you could drill a hole in the front of the panel opposite the dent and use a round ended punch thru the hole to knock the dent back out...just lay "face down" on a hard surface..working slowly and moving around the dent you could get most of it knocked back out..weld hole back up when done...for the bow thats in it, I have layed 2x4s on top of bowed panels and just stood on it and bounced a little..a little goes along way though..
I've used a dent riser to remove dents in gun barrels before...very similar to what mpc described...2 wedge shaped pieces of round stock pulled against each other with allthread...works great
mpc is a master metal man so what he says is all good..

Re: How to straighten panel

You can use a MIG to spot weld a stud or flat piece of metal into that low spot, at the very BOTTOM of that low spot, pull it out so the dent isn't holding the whole thing in, that dent is VERY strong so it needs to be "relieved" of that by pulling just the dent out.

Then lay the panel on the ground with a 2x4 wood board at each end to hold it up, then a 2x4 on top of that area to strike with a 4lb or so sledge hammer nice and easy and that bow would come out.

Here is an article on the subject where you weld a metal tab and pull it.

http://autobodystore.com/forum/showt...ck&=pogo+stick

With yours, that panel is so long and it's not bolted on, you could actually use IT as the "pogo stick" in the article. Put the panel standing up against something like a fence pole or a wall or something and hook the chain that is hooked to your vice grip holding the plate you have welded to the BOTTOM of that dent. Pull back on the top of the panel with the bottom of the panel up against the pole or wall and you can pull that dent out.

Hope fully this makes sense, it sounds kinda goofy I know.

You could also drill a hole in the back side of that panel behind the dent...ahhhhh, that may be a better way to do it. Drill a hole, then using a long drift punch so you can get through the hole down to the dent and push it out by hitting on the drift bunch with a hammer. After getting that dent out so it's relieving the pressure you can go back to the idea of setting it on two strips of 2x4 and striking the back with a hammer on another piece of 2x4. Then weld the hole up that you drilled for access.

I am thinking that would be better than welding a tab on.

Re: How to straighten panel

I've also used a cutting disc to cut out a section like where the dent is and either hammer out the dent of the piece you cut out and weld the piece back in or cut a section from a donor piece to replace what you cut out and weld back in....

I've got a po welded up mess on a IH stepside bed rail I'm working on now where I'm gonna cut out a section and just replace it because of what the po did...I'm shortening the bed from lwb to swb so that's generating me a donor piece to replace what they did...

cutting out that bent section would allow the panel to flatten back out...maybe without any hammering...clamp the panel to a strait edge and weld new piece back in....

between martin and mpc they are master's at what they do... I'm just using redneck problem solving so my ideas arnt always the proper/best way to do stuff...I'm by no means a pro..

Re: How to straighten panel

Wow! I can't believe it's that simple! I figured this was gonna be a real bugger to fix. Glad to hear it's this easy! Thanks for all the ideas to try!
