So because I'm on the UMN Formula SAE team, I have access to a TIG welder and like facilities. I'm thinking that I should build myself a header. Now, I realize that this isn't an easy project (I've never TIG welded before), but I'm willing to give it more than a few tries to get it right (i'll just practice on waste tube in the shop). What I really wanted to know was if you guys think its possible to do without the car right there. I won't be able to have the car next to me while I'm making the header (i'll be on the 4th floor). I'm afraid it'll be impossible to get it to fit without having the engine right there to mock it up on. I plan on copying annother design verbatum. Probably AN-R or bisimoto design. Maybe something a little simpler initially, but I want something that has a well proven design. Think its possible? Can I build a header that fits without something to mock it up on?
