well the most sad part of my duster is one hole roted in the inner finder from battery acid the other two the whole trunk about and one floor pan and well i need could use some pics of how to do a little sheetmetal patch work on floors maybe making templates and things

Look at my car I ahve one picture of where I replaced a floor pan. The big thing is fitting the piece. I made a template and left a 1/4in overlap. This is good for either trimming, or i have a bead roller where I could have a lip that tucked underneath. Fitting is key! Fitting is key! Get the picture?
When welding go slow, 3/4in at a time is moving right along when welding sheet metal. If your doing large areas that will be painted/exposed we put a layer of play-dough both top and bottom (about an 2in) to absorb the heat and not warp your panels as bad. Good luck!

I fancy myself as an old school metal worker. I have worked in metal fab shops since I was about 15.

Metal working is pretty simple, but if you want, you can get complicated. We can talk about molecules, annealing, and all that junk, but for patching panels, all you should really need to know is to go slow.

Use poster board to make a template. You can make the repair piece the same size as the hole and use magnets to hold it in place while you tack it in.

When tacking a panel, make small tack welds all the way around the panel, but do one on one side, and one on the other. Go back and forth and do one tack about every inch or so. Then, go in and tack between the welds. But take your time and let things cool off. Weld one side, then weld the other.

When working on body panels, going slow and making short welds is the key. Too much heat can warp a panel. Make short, 1/2" - 3/4" welds at a time. Don't use water to cool a weld because cooling to quickly can warp a panel too. Take your time, listen to a great CD and loose yourself in the project. Thats when the best metal work happens.
