Head tubes, 4130, mig, mild steel?
I am looking at head tubes anywhere I can find them, all seem to be made from 4130, nothing in the 1020 mild steel ranges. I've done a bunch of reading on mig welding 4130, seems like a mixed bag of opinions. Some argue TIG only, blah blah, I'd rather play it safe if possible and I only have MIG on hand. Am I over thinking it and worrying about nothing?
I haven't figured out how to relatively easily make conventional threadless (press 1 1/8" cups into tube) head tubes, maybe I need to get some stock mild steel tubing of some uncertain dimension and find a guy with some knowledge and a lathe?
Maybe someone knows where to get mild steel head tubes?
Doctor doctor, give me the news, I gotta bad case of analysis paralysis.
