Jamie,

Thanks for a speedy reply and a huge thanks for the links! I'll be giving these a try in the months to come. I think I'm going to enjoy combing through the TM website when I find the time.
I agree with you that the Smith's requires some getting use to. The same coworker who introduced me to using a mapp/pro bernz. setup, required a little training and some practice before he felt comfortable with the oxy/acetylene. It's safe to use if you know what you're doing, but it can be nerve wracking if you're just getting in to it. Personally, I like the flexibility it provides. I can go from working the smallest of joints up to large 1/2" bars (for my use this is quite large), simply by adjusting the gas flow. But sometimes quick and easy is best, especially when you're on a deadline. I'll be pushing to get a sievert in before the end of the fiscal year and I'll let you know how we make out with it.
Thanks again for the help!
Alan
