Yep, now I've done it. I can "play" with fire. I got a Mapp gas torch kit from the local Menards this morning for under $40. Not bad I figure. I know it's not an oxy-acetylene torch, but for the real light stuff (re-welding the shields on my push mowers etc...) it should work. So has anyone else ever used one? How thick of steel could I cut with it? I bought an extra oxygen tank to go with it. Any ideas on how long the MAPP tank will last during steady use? I've never tried one and am going to try it out cutting a 1" x 1/8" flat iron. And yes, the fire extinguisher has been recharged!
