I love the simplicity of this forge set up.I think having a little knowledge of this old skill could come in very handy if SHTF. Not only is this skill a valuable trade today, in a SHTF situation, you could use these skills to barter with and make some pretty strong defensive weapons. Heck, you could even make small skinning knives to swords to barter with too.
On this set up, one sink is filled with cold water to quench the metal, but if you can only find a single stainless steel sink you could just fill a bucket of water and still be good. In fact that may be easier, as finding a double sink may be difficult. I would check your local classifieds and maybe even the scrap yard and pick one up for free 🙂
A quick tip:
Low-carbon steel is fine for most projects, but high-carbon, S7 tool steel is better for shaping implements that need to hold an edge. here are a couple of great books on blacksmithing I would recommend. The Backyard Blacksmith by Lorelei Sims or Blacksmithing Basics for the Homestead by Joe DeLaRonde. I found a really great blacksmith 101 article that can explain the basics and also shows you how to build the pictured forge.
