Could this be a good way to weld autobody panels without distortion?

I would love to see a video of how to weld modern car panels. I'm working on adding a hoodscoop to a 2004 Mercury Marauder and I'm having a tough time controlling distortion on the 24ga sheetmetal. I have a variety of seems including butt welds lap joints, and inside and outside corner joints. Any t...

I have a miller that I love but man I would love one of these!

That looks like a sand casted part. Sand casted aluminum is pretty pure and I have had great results welding it. Much easier than die cast parts. Still there is always the fear of litigation if the weld failed and someone got hurt.

Thanks for all of the great advice. Here is my progression of welding. Actually taking pictures helped me pace the welding so I wouldn't rush it. http://www.everlastgenerators.com/forums/attachment.php?attachmentid=12256&d=1406424404 So a little rough at first but I turned up the cleaning (AC se...

I couldn't have done this. It top of the broken stud was about 1/4" down and it was only a 6mm stud.

All the advice given on actually welding the head appears good - will it work - probably - but it looks like the typical Chinese clone of a Honda step thru engine - off the importers here a brand new complete head including postage is around £20 - if you wanted to swap out your cam & valves it'...

Having the head torqued to a heavy plate or cylinder is a must. I would think dissipating the heat as evenly and quickly would be best. As for the welding, many of the "experienced professional" welders could give the best advice on technique, gasses, etc. I would fully weld the area with...

Too bad you didn't post "just" after breaking the bolt extractor (or, better, BEFORE you tried it). I could have offered you an easy solution. That said, I agree, I'd build that with the head bolted on, for the reason you suggested. Find a stainless-steel bolt in the correct thread, and s...

I recently picked up a small 50cc mini chopper. One of the exhaust studs was broken in the head. I removed the motor and tried to use a bolt extractor but the extractor snapped off in the bolt. I went a little extreme and cut the flange in the casting so half the bolt was exposed and knocked it out....
