Re:Operating propane stoves in cold weather....
I hadn't a clue that you were a physics engineer! Everything you said makes sense as I've worked with propane heaters since 1976 when I move to Colorado and laid brick for a living. I have the original orifice in the cart. I wondered about that. So, do you change your orifice during winter? Or, does it not get quite as cold. We haven't been above freezing now since Dec 21, 2012.
Jack I'm sure the manufacturer of my cart used the wrong solder, and what's amazing is they have made carts before Benscarts. I would think they would know better. It like laying brick with Cement (concrete cement) instead of using masonry cement. Or like putting water lines together with "super glue." Ha ha!
Thanks for your comment. I don't think many hot doggers are as desperate as I am. I have no choice. I have to work at least a couple of days a week this winter for sure.
