Continued from my introduction here. Great idea Jeff. I've watched quite a few videos this week and am really liking the idea. The choke system I pictured below seems to appeal to me a bit more than the "T" drilled thru the reducer method. I am convinced I can get a better alignment for my mig tip this way on the lathe. I also like the idea of the gas inlet being the threaded choke rod. The tips I found laying around are .044 so I think i'll need to get something smaller... why do these burners all appear so much bigger on youtube than when I start to mock them up? Can I use a 1" pipe with a 1 ' to 1.5 ' reducer instead of a 3/4" pipe? Also, can the main pipe of the burner be a stainless steel nipple instead of the black iron? Would be a lot easier for me when welding on the flair... ok ok the bling factor plays a little roll too. Was thinking one of these welded right onto the 1" pipe, or maybe sleeve the one inch up to 1.25, then flair from there? trying to avoid the exposed internal threads messing with my gas flow. Any suggestions sure would be appreciated, Sincerely.
