Default First Panel repair help needed.

Hello Group,

I have this top from a Frigidaire refrigerator that a friend is restoring.


The top was a mess and I have progressed pretty well.


The question is, It has a curve in the top but the top is supposed to be flat in the center. What is my next step to flatten out the top?

Looks like nice work so far. Do you have a shrinking disc? All of the creasing has stretched the metal. It needs to be shrunk back into place. Hitting the high spots with a shrinking disc is about the best way to do this. You could go after it with an O/A torch but the shrinking disc will pull the high spots in more evenly in my opinion.
If you haven't used one before Eastwood has a bit of a tutorial on their site.
I'll be using one or two to pull the rest of the deer damage and patch repairs out of both front fenders on the wagon.

Hi Mark,

Thanks for the response. I do not have a shrinking disk but I have read about the wood disk idea, maybe I will check into that. I actually have had good luck with O/A shrinking in the past but it was a smaller area than this one.
I will take your suggestion and see how I do this weekend.
I'll report back when I have good results, or if I get my self backed into a corner.

Mr fixit

If you do not have a shrinking disk you can do what I did back in the 60’s. Take a 7” grinding disk and mount it back side out on your backing pad on your 7” side grinder. Use this arrangement to heat up the high spots.

About the flat raised area - and holding it flat while bashing out the rest of it .....

I would cut some 3/4in plywood to fit in the recess side - good one-side stuff (not the CrapDooXcrement)
And then stack another twin of that up on top with a big heavy weight on it, to pin the panel to the bench - while working out the crash hash all around it.
May need to elevate the stack up off the bench to get hand and dolly underneath.
Then slap and straighten and shrink around the perimeter area, using the workbench as a depth/height guide.
Go back and tune up the center a bit now and then - don't go overboard on THAT. It will come along as the perimeter comes around.
Good luck, and write back as the scenery improves.

(Warning: overdoing shrinking on flat thin areas can be detrimental to your joy and patience.)
