February 20, 200620 yr Hello. I have a question, how do those little kerosene/gasoline blowtorches work? Here's an example of what I am thinking of: http://www.backyardmetalcasting.com/ccfurnace01.html thanks eversomuch, Archie
February 20, 200620 yr Not really sure, but from looking at them they seem to work much like old Coleman lanterns and stoves. You pressuize the fuel and use it. I have also been told that they ARE time bombs. I know I have had my Coleman stove flare up ( not really an explosion but it was good enough for me) Ralph
February 20, 200620 yr Ralph is right. They work much like a Coleman stove. We had one of these when I was a kid. Ours was designed to use gasoline, preferably white gas, but we always used regular gasoline. You would fill the tank, and pressurize it with the built in pump. Ours had a screw on the underside of the burner that you loosened to let raw gas drip into the pan under the burner. When the pan was almost full, you closed the screw and set the pan on fire. When the gas in the pan was almost completely burned you would open the burner valve. The burner assembly would be then be hot enough to vaporize the gasoline coming through the burner. BT
February 21, 200620 yr Excellent bit of information on old gasoline torches like you mentioned a this site. lots of good little tips on repair and what to look for if you plan to buy your own.http://www.blotorches.com/torchfix/torchfix.html If you do a search on gasoline torch in yahoo you'll also come across a gasoline/oxygen cutting torch system that's cheaper and safer than oxy/acetelenewww.petrogen.com
February 21, 200620 yr Author I have seen petrogen, and it is very cool. I am thinking that if I used a blowtorch setup with petrol, diesel (there is a torch somebody built at one time or another which uses diesel that got me thinking) or even biodiesel, (which would make me very happy) this would, like petrogen, make sure that there were no parts under pressure, so the time bomb effect would be avoided, and it being a blowtorch setup would not use oxygen tanks, but I could still get a flame for sodlering or brazing or heating up iron in very small localized places. I will try it out, I think. :D
February 22, 200620 yr One of Guy Lautard's "Home Shop Machinist" books has a whole chapter on gasoline torches. How to build, what features are important, etc. Might be worth buying a second-hand copy on Amazon and reading it - lots of other good "metal stuff" in that volume...
