I've found some loose rail along an abandoned track on the other end of the island. The thing is all the rails are full length and heavy as the dickens.

I'm kind of new to the cutting torch and not sure I'll be able to pull it off. The thickest I've cut so far is 1" mild steel. Sometimes I've done just fine while other times I've struggled a good deal with only half penetration and lots of molten metal blow back. Anyone got any pointers? |
You will have better luck if you equip your torch with a size 1 tip, set the acetylene at 3 to 5 psi, and run the oxygen pressure at 30 to 35 psi. This is the smallest setup recomended by Victor torch manufacturing for producing a quality cut on the thickness of metal that you are after. Crankin up the O2 to 80 might enable you to blast through the track, but a small cylinder will only last for a blink at those preassures (maybe not even long enough to get the job done)
