Measure, model, fabricate, weld, grind, weld, grind, weld...

The bitter cold in the DC area over the holidays kept me inside and got me back to doing rust repair on my 65 Corsa. I have had this car on a rotisserie for awhile and was glad to get back at it.

This thread shows that an unskilled enthusiast with a bit of time can get decent results in addressing rust repair.

First pic shows the seam and part of the front passenger side corner of the car already cut out. Note the rust inside the wheel well lip. That was one patch. Next was the curved part on the bottom (Eastwood shrinker/stretcher works very well for a hobbyist like me). Then the flat extension on the bottom of the corner...then the flat that fills in the wheel well. That part is just tacked in so far. Final patch will be the body exterior panel...will try to cut a piece from the parts car for this patch to get the curve right.

All in all, five patch panels needed for a crunchy front corner. Poor welding skills combined with persistence work out pretty well for me.

The whole front panel has been replaced and brazed in in the past...fun to hit some brazing with the MIG...good light and spark show.

anybody can do this with a MIG welder and high pain threshold. Second pic shows my cardboard mock up of three of the needed patches taped together.

First patch. Lots of blobby welding....leading to grinding...etc.

Thanks for posting! I have a beater that I'm going to start practicing on before I try something I care about. You give me hope!

Fourth one (in progress...but tacked in place and the seam is straight and will look great).

Will, the hardest part for me on this particular project was taking the cutting tools to the rusty corner. Once all the bad was cut out the next steps were easier to figure out. So...I would change the title of this thread to "Cut, ponder, measure....etc....

Hey Frank,

Yes, that is it. Works pretty well. I can bring it by for a test drive if you want. Need to come visit you one of these weekends I am out in Catlett.

Ay Darrin,

looks good and your doing fine.thumbs up

I have always took pride in the fact that with a little practice and patience, I can do a lot of these things every bit as BAD as the so called professionals!
The more I have done over the years, the better my skills.

Great work!smileys with beer Please keep us posted.

Thanks Dave...that is my new mantra...at least I am not paying someone else big bucks to do just as bad a job!

I was visiting a Corvair friend a couple of weeks ago and he had a beautiful non-Corvair that he had painted a few years ago. He pointed out the only small run in the whole paint job first thing! The car was huge and beautiful. Thankfully I am not a perfectionist of that sort. He did such good work overall, but saw that flaw every time he looked at the car.

Luckily, I will have multiple flaws to point to so will not be fixated on only one! Life is good.

Darrin, great job. I can't wait to get my MIG welder. It's on my list. I am going to practice on my 86 C10, which are notorious for rusting everywhere. I am going to try using magnets to hold the pieces in position when I tack the patch panels in place.

Rory, I use magnets and c-clamps both. I find it really helpful to back the weld area with copper plate if it is accessible. Less burn through and can fill slightly larger gaps this way. Also helpful on thinner metal due to rust.

Mostly done. Before, patch panel sitting in place, and after welding and grinding. Seams inside the trunk look good (not pictured).

Sure does look good. I'm glad you decided to tackle it, most are scared to venture there.

Here's a tip: I save the breakfast cereal boxes to use as template material. If you cut them bigger than the patch size and then press the cardboard hard against the total edge of the cut, you can get very accurate templates by cutting along the "dent" you put in the cardboard.

Another tip is the quality of the steel in original parts is far better than the steel I've been buying at the local welding supply. Keep scraps of old parts that are usable for future patches.

Darrin, really nice work! What's your preferred steps in grinding down the weld? I always struggle to find the point where it is flush without thinning the surrounding metal. Even when you cut back to "good" metal" I believe it's a little thinner then the original. Do you ever "discover" bad metal as you're welding, and blow out a another hole to patch? I've gotten pretty good at plug welding.

We diemakers have a saying. "We grind it off and welders weld it back up."

You've just demonstrated why I have always said that paint and body work is an artist's work. Which is why I can do everything on my resto, but leave that to the true artists. As for me, I've tried welding. I can burn a hole in quarter inch plate.eye popping smiley

P.S. Great job! thumbs up
