Cutting railroad rail with a bandsaw
As part of the scrap deal I mentioned earlier (antique stone planers),
I also acquired two railroad rails. They were used for railroad service before, and after that they were used for some custom stone cutting machine. I thought that I could bring them to my warehouse, cut up into 11 inch sections, and sell as "railroad rail anvils" and ship in flat rate boxes. However, I do recall that railroad rails work harden from years of use, and I am concerned that they will damage bandsaw blades. Any other cutting method would be uneconomical, so mu question is, can a bandsaw cut used railroad rails. Thanks |

But if not set up for friction sawing (absurdly high blade speeds, does what the name implies, DAGS) you'll probably need to experiment and see how the hardest teeth you stock do on a chunk of the stuff. Or set one up for friction-sawing, and have that in your arsenal for the future. -- Cats, coffee, chocolate...vices to live by Please don't feed the trolls.

A long-dead machinist friend once found some OLD two-piece rail sticking out of the ground. He cut off pieces and donated them to a museum in Pennsylvania. ISTM he said they figured out they were Civil War era. Rolling rails was a real challenge in the early days. At the beginning of rail, they were wooden rails with wrought-iron strips on top. Then there were a couple of interim steps -- I think the two-piece was one of them -- as steel mills developed the capacity to roll the kinds of rails we have today. It was a major impetus to the development of steelmaking and rolling-mill work. Like firearms and steam power, the demand for rails was a primary motivating force that drove the modernization of several metal producing and metalworking industries. -- Ed Huntress |

Most railroad iron is harder than a whores heart. Ive machined a few for people...and the first one was an eye opener. Now I build a bonfire, stick in the material and then when the coals are hot...cover it with vermiculite (which is getting damned hard to find btw) or sand. The next day the track is easy to cut/machine. You need to simply get it red hot and then let it slow cool. If I were you..Id either cut em with a Big abrasive saw ( you should have one by now) or flame cut. Doesnt take much gas to slice one up. Include a printed sheet on how to anneal them and people will love you. It can be done on a BBQ if the chunk fits in it...but it will take some gas to do.

I haven't tried it so you may be right... but a slitting blade acts much different than a grinding blade. You have to be really careful with them and not let them twist in the cut or you will end up with pieces flying all over. Anyway, I would give it a try and then try cutting it with a hand hack saw and see how it acted... -- Leon Fisk Grand Rapids MI/Zone 5b Remove no.spam for email |

New, as-rolled, it's typically 400 - 430 Bhn. That's pretty hard for cutting with a steel blade. How much/far in do they work harden? I don't know specifically, Leon, but it's usually described as being fairly shallow. I would try cutting them across the top with an abrasive slitting blade for maybe 1/4 to 1/2 inch deep and then finish up with a band saw. My 9 inch angle grinder would do that much in a reasonable time frame. You might be surprised at how they cut. My "anvil" is a piece of track about 8" long, which was cut, originally, with a big mutha O/A cutting torch. I took my big mutha Milwaukee 6", 6.000 rpm angle-head grinder snd ground off the edges, plus I ground the track surface smooth. I couldn't believe how tough it was to grind. My Milwaukee is the model they use for grinding construction and bridge I-beams for welding, and it usually goes through structural steel like butter. I haven't tried it so you may be right... but a slitting blade acts much different than a grinding blade. You have to be really careful with them and not let them twist in the cut or you will end up with pieces flying all over. Anyway, I would give it a try and then try cutting it with a hand hack saw and see how it acted... Yeah, it's certainly worth a try. I think it's pretty clever of Iggy to think of selling those pieces. Now we'll see how practical it is to do at a reasonable cost. -- Ed Huntress |

I've been really impressed with the "ultra thin" slitting wheels made by Diablo, but they are spendy. The HF ones come in second place, and are a lot cheaper so I usually just buy those. The thin wheels not only last longer but they cut quicker as well. I go really slow and make sure everything is lined up straight and square, and make sure I'm covered up really good (safety glasses + faceshield and a leather apron at a minimum). Jon |

Any other cutting method would be uneconomical, so mu question is, can a bandsaw cut used railroad rails. Thanks As someone else noted you can cut them with a bandsaw set up for friction sawing or you can use one of the abrasive cut off wheel machines that are small enough that they can be moved around. Local shops that sell random lengths of steel routinely use them on a daily basis so I assume that wheel life is reasonable.. -- Cheers, John B. |

Try one , cut it lying on it's side to present the thinner section(s) to the blade . -- Snag Yes, thanks. I saw advice somewhere to cut them upside down, to start out with softer material. I will do it that way. My bandsaw blades are bimeetal, 1 inch wide Starrett blades. Plasma cuts cleanly to the recommended thickness, but will cut much, much thicker stock if you want it to. Wouldn't a plasma cutter do the job quicker and more easily, except with regard to later cleanup? (if you do clean it up) You could use that to cut the horns, too. Preshaping might get you a better price. I live in the real world, I need to cut these rails cleanly and cheaply, a plasma cutter will do neither. i Perhaps a carbide tooth blade would do the job if one is available in that blade size. There as a lot of well annealed rail over in Lac Magentic Quebec. |
