ran across this site:http://www.petrolwin.com/ a gasoline powerd cutting torch?i`v used air over deisel pots for heating and they were dangerous enough! but gasoline?it never hurts to look,unless they`r WELDING!

Reply:This past winter I worked with a guy who had used one in the field.  He said it was OK but no better than oxy and propane.  When they tried to use the unit several months later after storing it they couldn't get it to work so it was discarded to the back of the tool storage.I would be concerned if the fuel hose was cut but then exciting things happen with acetylene anyway.
Reply:I looked in to it for scrapping too but it seemed expensive and LP would have worked about as well.www.urkafarms.com
Reply:Very pricey and I don't think I like the whole gasoline idea.  We had a piece of equipment in the Navy called an exothermic cutter.  It used oxygen and a metal rod (consumable) and burned very hot!!!  I would cut steel, stainless, aluminum and they claimed glass.  Didn't give a very quality cut.  It would have been great for demo work.  Don't know how expensive the rods were.  Anybody know where we can get info on it.Ron ShopFloorTalk Millermatic 350P, M-25, M-40 gunsDynasty 300DX, Coolmate 3, Crafter CS-310 TorchTrailblazer 302, 12RC, WC-2430A spoolgunSpectrum 2050Thermal Arc Plasma Welder PS-3000/WC-100B
Reply:Shade Tree, that's what is commonly called a burning bar, looks like 1/2" black iron pipe with a bunch of iron wires inside of the pipe.What is actually happening is the pipe and wires become fuel and the oxygen supports the combustion.  The chemicle reaction isn't all that different from what is happening in the O/A cut once you've established a cut.Those things are PURE NASTY, and will burn thru about anything, from reenforced concrete to steel as long as you don't mind the backblast.Appreciation Gains You Recognition-
Reply:Shade Tree,over here they call that a Thermic Lance. You can make one from iron gas pipe packed with O/A welding rod, or buy the stuff ready made in screw-together lengths.To light it you turn on the oxygen (it uses a LOT of oxygen) and arc weld on the cutting end, then you jump back - fast!Like Franz says its very scary to use, but will cut almost anything.The last site I worked on where we had one the entire rig was stolen one night. We found out later that someone had tried to use it to open a safe. It opened the safe ok but incinerated everything inside and set fire to the building.Take care.I'm not very clever,But I can lift heavy things.
Reply:Hey!  Now I remember what it's called, and exothermic cutter.  I was trying to explain to my dad what it was.  On our friggit it was classified as a piece of Damage Control equipment, in fact the only one the general crew couldn't qualify on.There is one true piece of armor on a Perry-class, and that's the missile magazine.  4" thick.  Get a fire in there or restricted access, it's to the exothermic with two hose teams on standby.  I was told it'd open a hole to spray in in a matter of seconds, and a man-sized hole in a couple minutes.  Never saw it working.
Reply:HMMM, sounds like a "straight lance" to me.. heard the old timers speak of such when i was first starting out in the bizz...had the opportunity to test one out @ TAMPA SHIP when we were bldng a DUMP SCOW barge for new yawk city. this thing was 2 watertight halves hinged together and remotely operated[from the tug] to HYD open and DUMP garbage into the sea! [sounds GREAT, huh?]anyway, we used a 3' long x 8" dia "test pin in the hinges to set and weld the hinges in place...well, you know what the welders did, they jumped on the easy side of the hinges and poured the mig to it! [and securely LOCKED the test pin in due to weld draw!] the outside machinest est. some 5~7 days to set-up a "boring bar" to bore the pin out..i suggested a "lance" to burn the pin out! YARD MANAGEMENT was NOT amused! but the director of QA [qaulity assurance] was an old NAVY director of vessel const. and when he heard that i could run a lance, JUMPED on the idea and so we proceded...1/2" pipe [nothing inside] 1/2" ID ox hose[str hook-up to manifold] 3/4" pipe "giudes" and a big pc of hard gasket material w/burning sheild "window"at the valve end of the lance....heated both ends of the pin [starting end untill melting] open the ball valve and start pushing the lance through! the man kept heating the other end[slag free zone] untill we had gone clean through!MY GAWD! the only time i`v ever been burnt as badly by molten slag was when i lit 2 huge kettles of THERMIT to pour the weld on the rudderstock/prop shaft castings![another story]but when we were done, we had an 1 1/2" hole burnt through the pin! cooled said pin by running water through the hole and porta-powerd the pin right out! 5 men-8hrs and the deed was done! i was then pulled from the boilermakers team to work for QA [another story]took 17' of 21' of pipe to burn a 3' pin!now, we have something called "BROKO RODS" [like a lance except its electrically started by a welding machine and the rods are packed with magnesium, i think]used these a few times lancing pins out of crane bodies and such.....Last edited by kllrjo; 05-08-2004 at 11:26 AM.it never hurts to look,unless they`r WELDING!
Reply:Thank for all your input!  Hey rusted, what Frigate were you on?  I was on the USS Harry W. Hill (DD-986) San Diego a Spru-can.The rod we used on the exothermic cutter looked like a peice of sheet partly rolled and partly crimped up.  I was told it was bimetal.  With the info above I am guessing Magnesium and iron or steel.The big question is does anyone know were you can get one?Ron ShopFloorTalk Millermatic 350P, M-25, M-40 gunsDynasty 300DX, Coolmate 3, Crafter CS-310 TorchTrailblazer 302, 12RC, WC-2430A spoolgunSpectrum 2050Thermal Arc Plasma Welder PS-3000/WC-100B

Reply:i was lucky enough to get a chance to try it out it gives a hell of a cut but thats it all it does is cut.if i had a job where all i had to do is cut THICK AND DIRTY material i would love to use it.its safer than o/a and gas is always availible.i hate starting a saturday project and running out of acetylene or oxygen.
Reply:If your doing a lot of cutting of thick, dirty steel this torch is probably worth the money. It burns through thick nasty multilayer steels really well. For ordinary cutting it doesn't work so well. Its a pain to get started and it uses about double the oxygen as a regular torch. The gas has to be fresh. It will not work if you fill it out of gas cans. Some of our work takes place in remote areas that only get fuel deliveries once a year so the gas is to old to use. Unless we have a big cutting job at the shop we don't use ours.
