AC_Hacker & DC-X, thanks for the response! I'm glad there are 'alternative' thinkers out there who challenge the accepted practice. While I'm all in favor of following the process if you've got the equipment, if you don't have a ready source of Nitrogen, it's time to ask, "Are there alternatives?"

I like your informative analysis, DC-X, it is extremely useful in getting a perspective on the problem. It hadn't occurred to me to use propane! I like it!

I will pull a vacuum, however, since I already have the equipment. I'm a woodworker and use vacuum forming for bent laminations.

I'm intrigued by the fittings you referenced. Have you used these? Considering that I'm a newbie when it comes to making flares, would you recommend these as an alternative?

Thanks again,
Tom
