Damn Louis! You been practicing with your TIG skills eh?? Looks good! You will love the Anti-rollbar for sure!! She will launch hard and straight!!! Will be nice while burning curves too!
To be honest the only Tig Welding I have ever done is on the Ford 9" that I just built and a few small things here and there. As far as Steel, Chromoly, and Stainless goes, I think I have it nailed pretty good. That old school Oxygen/Acetelyne welding from when I was a kid is coming in handy now when hand dipping the rod. Funny how that is.
I did get a chance to mess around with some Aluminum the other day. I was very surprised at how well the welds came out. Seems about the same except Aluminum likes it real hot and you need to watch the pedal. Pre heating with a propane torch is supposed to bring all the impurities to the top so you can clean them off with Acetone and all your tig tips, tungsten and all Aluminum tools need to stay aluminum tools or you will contaminate your welds bad. I will goof around some more with aluminum and post some of my aluminum welds.
