![]() Standard Specification for Steel Track Spikes. Railroad spikes can be gathered from old tracks, purchased in antique shops or purchased from train enthusiasts, and they are turned into a variety of useful and creative tools.ĪSTM A65-01. Railroad spikes, which have been used on railroad tracks for more than 100 years, are collector's items for train enthusiasts and historians. One such object that you may not have thought much about is the railroad spike. The HC spikes are spec'd to never exceed the boundary between mild steel and medium steel. Many people enjoy taking uncommon objects and making practical tools out of them. Buy quenching in Rob Gunter's 'Super Quench' you can toughen up a HC RR Spike but it's not really in the league of proper knife hardness's in my opinion. Realistically you can (and probably should) harden it with a brine quench, but tempering it is where you’re going to want to be careful. (The Tuyere, newsletter of the Illinois Valey Blacksmith Association) If it’s a railroad spike it’s somewhere roughly between something approximating 1020 to 1045 carbon steel. This is the most popular class for teambuilding, families, and other groups. In 3 hours you shape a blade and handle, learn to grind, heat treat, and finish a knife. With this in mind, be aware of a higher carbon content and work with the material accordingly. Railroad Spike Knife Class is the perfect beginner knifemaking class. The spikes are barely heat treatable and won't hold an edge very long. 80% that we would usually call high carbon. HC on a railroad spike does not necessarily mean high carbon, it may mean highway crossing, and these spikes need to be stronger for this part of the track. In seasoned oak, another experimenter needed 4,281 pounds. Early experiments showed that pulling out a 9/16″ × 9/16″ spike driven 4¼" inches into dry cedar required on average a force of 857 pounds. A spike with the wedge driven across the grain will have about twice as much holding power as one driven with the grain. ![]() Its square cross section gives a railroad spike much higher holding strength than a fastener having the same amount of metal but a circular cross section has roughly speaking, about 50% more. The wedge is driven into the tie across the grain, that is, parallel to the track. The spikes used to fasten T-shaped railroad track to wooden ties have an L-shaped head and a square shank.
