Before welding the inner patch in place, I wanted to take advantage of the hole to access the inside of the outer fender panel. This had a PO repair with LOTS of bondo.

The fill was at least 1/8 across the entire panel.

To minimize the mess I mounted the Fein dust shield on the angle grinder. Not 100% but much better than without it.

Got the panel cleaned up, and did some initial smoothing. More work to come.

I also started on the top of the sill. This normally has two layers of sheet metal, but I decided to add a third inner layer patch. This extends about 2 inches forward and rear of the hole.

Here it is welded in place. I will need to grind this down to fit the "middle" panel patch.

And at the same time I tack welded the inner fender wall patch, and got the edges aligned.

Did some grinding and then tried to finish the butt seam welding around the patch. Got it done, but very frustrating with lots of burn-throughs. The final result is ugly, with lots of thick spot welds and big boogers. That will lead to more quality time with my grinder.

After a couple of hours of quality time with my angle grinder and die grinder, things are looking better. A few spots and holes to re-weld.

Getting ready for the next patch, the outer layer on the top of the sill.

I feel like I am in a groundhog day loop with the inner fender wall patch. After grinding yesterday, I checked the weld with a light inside the fender. This revealed a Buch of pin holes and thin spots, and a few segments where the weld did not penetrate.

So weld (#2) all suspect areas.

Check with the light inside again, more holes!

Tomorrow, if I hear Sonny and Cher on the garage radio, I may go back to bed.

Boy do I know that pinhole routine. Thank goodness I never woke up to I've Got You Babe. (IMG:style_emoticons/default/av-943.gif)

Well, I was hearing "I got you babe" again today for sure.

After grinding (3rd time) I had more holes and bad weld bits, especially in one spot.

So I finally did the right thing (I hope) and cut out the worst section. The size and shape shows where I was chasing a growing hole, especially into the original sheet metal.

I formed a new mini-patch and welded it in place--much better.

At the same time, I welded a few more holes around the original patch (4th time), and then ground them down (4th time). A quick look showed only a couple of pin hole around the new mini-patch. I might be able to beat the groundhog!

BTW, here in the back(!) side of the small area I cut out. Pretty nasty (and not the work quality I am aiming for).

I beat the groundhog!

I did hear a faint echo of Sonny and Cher, but after welding and grinding just 3 or 4 spots, the inner fender wall patch is done. Not pretty, but should finish fine after some cosmetic work later on.
