I would use 16g 1100 Well I use 1050A which is the same as your 1100 I believe. This is what is used on cars like Aston Martin so good enough for anything. Weld with O/A, you don't need anything special I have used lots of torches and I have had no problem welding with any of them. Use a strip of the parent material as a filler rod (why would you use anything else?) You want to be able to dress the weld out so if the weld is made of the same material as the rest of the panel there will be no probelms.
Its not possible as far as I know to weld with propane. I really recoment that you learn to gas weld ally its not too hard, it just takes practice. David

David, I've used propane in place of acetylene to weld platinum. It welds cleaner and doesn't cause the platinum to harden as it does with acetylene. An acetylene regulator will also fit a propane bottle. Never tried to weld aluminum with it but it is certainly hot enough to do it. I'm talking propane/oxygen torch welding.
Looking at some heat charts on these internets it looks like the flame temperature for oxy/propane is about 1000 degrees F cooler than oxy/acet. It's about 4500 degrees. I believe aluminum melts at around 1100 F. Last edited by bobadame; 06-28-2011 at 06:03 PM. |

Welding with propane
I posted this before, but here's what you find at http://en.wikipedia.org/wiki/Oxy-fue...ng_and_cutting
"Oxy/Propane does not weld steel because it does not create a carbon dioxide shield around itself." However, on aluminum it's a different matter, see: http://www.tinmantech.com/html/alumi...ng_article.php If you look at his site, he offers special tips for propane welding.

There is a whole lot more to an oxy/acetylene flame than just how hot it gets.
As Overkill says the oxy/acet flame creates a shield arount the weld puddle much like the argon shield when tig or mig welding.

Bob, One thing to keep in mind, although the regulator for acetylene will fit the propane bottle you really need a propane or multi-fuel rated regulator and hoses since the rubber in the hoses and the regulator diaphram can degrade and leak when used with the wrong gas. As far as heat goes, I use an oxy/propane torch for glass work and it gets hot enough to melt borosilicate (pyrex) glass and quartz at 2500-3200' F, so there is plenty of heat available. Like John said though, there is less carbon dioxide formed in the burning process, but I don't know if it will be sufficient for shielding, even with the flux on aluminum...but that is something to investigate. Cheers,

Dan,
While you're probably right I just thought I'd mention that the Victor SR4XX and VTS4XX regulators use stainless steel diaphragms and therefore won't care. Not true of the cheaper small regs of course many of which use viton or the like.

Nice project
Ray,
Here's the thread link on my C5 Corvette based '60s era sports car project: http://allmetalshaping.com/showthread.php?t=2264 While I elected to build the body with a material other than aluminum, I agree with the popular opinion in this thread that you should build yours in aluminum. I didn't have knowledge or experience with shaping metal when I started my project. Now that I do, and I would make a different choice if done today. I too am taller than average (6'5"). I've learned the importance of having longer foot wells and larger doors to make it easier for me to get in and out of sports cars. I'd suggest you spend some time mocking up door openings while you're making a buck so you can "practice" getting in and out and make sure it's comfortable. If by chance you're open to a body other than Scarab, like maybe a Ferrari 250GTO, let me know. I might be able to help you out with measurements, etc. Best of luck with the project!!

Joel, Thanks for the input. I have built a Velarosa 240z based, daytona coupe 240z based and daytona coupe tube framed 351 w powered car all glass . Us tall guy's should not build sports cars..............but here we are again. I fit ok in the C3 vette tub. But the long doors and windshield will be a challange from a styling point but i have to get in and out .
I could look at my Daytona Coupe all day but driving it was a nightmare, Noisy,hot and could not fit at all. . Taking others advice i bought a 1/24 scale model of a 70 vette and cut it up and have started re-shaping it with mud. Hope to see what it turns out like.
