Saving Rocker panels

I wasn't happy with the rocker panels I bought. So I sent them back and decided to fix the ones I have. At least I know they'll fit the car well. They were rusted behind and had some holes within. One was missing the rear bolt also. I media blasted them and they cleaned up pretty good. First off though I want to say they are really straight and have no dents. All the problems seem to be on just one. I'm no professional. I'm not afraid to jump in and tackle something. So here goes. :P

You can see the rust out areas. I cleaned up the end because the metal was very thin there. I'm going to make a piece to bend and weld into the corner. It has to bend around the back and have the bolt that connects to the car. This might take you a couple of times to get right. Just don't get discouraged. I will be using a welder, hole punch, panel flanger, throatless shear, die grinder, and needle nose pliers, and a piece of copper to do this job. If you don't have all this, don't worry I've done similar before with far less. You will need a welder though.
The first thing I did was go to the good panel. I used a piece of paper to copy the end that was missing. I even copied along the top of the panel a little further to insure I was going to have the correct angle of the end. I flipped that upside down and that will be the pattern for the missing part.

Before I could bend it. I punched a hole in it for the bolt. Put the bolt in and weld it. You can see the dotted line which represents the area that needs to be flanged. This whole piece will sit behind the panel except for the top which will sit level. Take your time and weld it. Don't have your welder set to high. You'll burn through it. I did this on #1 power.

It looks good and the fit is perfect. Now back to fixing the holes in the panel. You could weld a piece of metal behind the hole. That could trap moisture later though. Take a piece of copper. Put it behind the hole. I used a magnet to hold it there. Your weld won't stick to the copper. Weld the hole shut. Grind off any excess and remove the copper from behind. Take your die grinder or sand paper and clean up the back too. You want the whole piece clean when you paint it. The next step for me is to paint the entire panel with epoxy primer. It is a self etching primer and contains zinc phosphate as a corrosion inhibitor. After I paint it (2 coats), I will do the body work. You want to paint the panel first to seal it. After the body work, I will paint it again two coats of epoxy with a reducer to get it ready for the base. I hope this was helpful. The panels we have on our cars now are much better than the ones you can buy. And if they're on your car, you'll know they'll fit. :P

Looking good Brady! Have you had any issues with the magnets messing up your weld? I was having a terrible time until I figured out the magnet was the problem. I asked the local welding supply store about it and he said the magnets do interfere with the weld and should only be used for tacking. Seems kind of funny, since they were "welding magnets".

That's funny. I'm glad you said something. I remember the weld acting differently. Wasn't sure why. Maybe it was the magnetic effect. Did they say it would make a weaker weld?
Here's the finished product. :P

It's funny the magnets don't mention it on the pkg.

Sometimes if you weld near the magnets the current can de-magnetize them.

I only use the magnets to tack weld. After you get a tack weld in place you really don't need them.

That's all I do myself. I do remember when I was welding these, it was as if the wire was just melting. No sizzle. Sometimes I hear that nice sizzle. But not all the time. I did have the power setting to high and made a small hole. That was easily fixed. I don't know if it's something in the metal or what. The welds seem to hold.
When I weld my seat belt guides and wind screens, I try to break them afterward. I think it only happened once. The gas was really low. So I replaced it. At least I know they'll hold up. It takes time and a lot of practice to become a good welder. Restoring this car gave me a lot of practice. I've learned a lot along the way. Still I'm no professional.
