There's NO WAY you could do this with a Mig, which is why we are all so skeptical and curious as to the final outcome.

As for the shrinkage, it's the same theory as in the "Metal Bumping" book. By stretching just the shrunken area back out, the rest that got pulled in with it will return to it's natural shape by itself. The key to that process is recognizing where to shrink and where to stretch...

I would still like to have a Tig for aluminum and stainless welding but it is an expensive tool to use once a year.
This still is an issue but if you don't overstretch to begin with you don't have to worry about it. This is one of the key points with this method, you weld, it shrinks, you stretch it up until it's correct. If you "Hammer weld" you are likely to over stretch one area more than another.

You know another thing Henry, the "hammer welding" method has been so ingrained in my brain that I am not sure if I didn't "see" just what I am talking about in those books because of this. The more he explained this stuff to me the more I remember seeing something as he was saying in videos or books. I am not talking what I am telling you exactly now, it's more about controlling the metal, how this is done, I simply don't remember really getting that like I am with his telling me. I know that a lot of these books and videos are made by guys who know how to do the work, that doesn't mean they can "Put the tools in your hands" in the print or video so you REALLY see and feel what they are doing. I know I have seen a lot of how-to write ups that leave a LOT of detail out.

I think the very principles are there, they are just written in a different way so I never saw it.

The way he has told me one on one over lunch it has resinated and made sense.

Yeow! But you know why you do that, you love seeing the people dance and have a good time. Focus on that, not on the work before and after. Tonight will be a blast!

Your roof looks great amd I am glad this is working out for you but I don't think I will be practicing a one pace system on my 46 inch long door.

They did Mitch but they would be scarcer than hen's teeth. I had a friend with a 3 speed straight shift 6 cylinder but it is the only one I have seen. It was a bare bones Malibu 2 door.

Filling holes with MIG

Here's my work for today. I cut the bracing from the bed floor of the S10 with son's plasma cutter and burned through several spots. I've had fair success filling such holes with a series of tacks from my MIG, backed up with a flattened piece of copper tubing. Here's the progression...

awesome cars! WOW!

Today I went to the Santa parade with my daughter. She loved it but got a little too happy about not being pushed around in the stroller so on the walk back from the car I just had my wife wait while I got the car and met them. As we were leaving I saw a sweet tricked out Impala on the side being fixed on the side of the road...just minutes after it was showing off driving by on 3 wheels. lol It was a NICE ride though. The car club it belonged to was called family first. They had some cool Impalas. The parade ended with the Antelope Titans marching band so that was cool. I'm hoping it's the high school my daughter goes to. Time for some me time and will go down the block and play some hoops.

I tried out my new plasma cutter today...All I can say is WOW!!!!I would've had one years ago if I ever tried one out...I bought it to burn out spot welds insted of drilling because the car I'm working on has some steel that just burns up bits and sawzall blades...It so fast its almost TOO fast.I can burn out about fifty welds in the time it takes to drill out one...since I never used one before I was playing around a little and found out I didnt have to burn a hole all the way through if I turned down the current to about 13 amps and turned down the air pressure it will only burn one layer of steel at a time just like a spotweld drill does. I replacing the side of this car inner structure and all...what took two of us all day only took me two hours to do all by myself...I'm still getting used to it but when I get it dialed in watch out...worth every penny....

after burning all the welds I seperated the cosmetic outer skin from the inner structure you can see how the plasma cutter burned through the outter skin leaving the inner structure without a holejust a nice clean spot to weld too when its back together...If I didnt mention it before this is an awesome tool.Anybody want to buy a chop saw ,sawzalls,or complete set of torches????

Like I said before,, Many of your tools will now stay in the box.. After you learn the tricks. You will wonder how you got along without it.. My cheapy c-50 made me a believer years ago and yes the cheapies will cut 1/2" steel. The next larger will sever 5/8" not quite as pretty of a cut but doesn't overheat your stock.

.....isn't it fun when a tool works like magic .....

I have a magnetic-induction tool that heats seized bolts and nuts with the push of a button instead of a flame and it feels like cheating...
