A while ago, I decided that I wanted to start doing some more serious metal-working and start in the art of manliness: blacksmithing. My only trouble was that I couldnt find many easy ways of building one, so I began planning and building for myself! Hope this helps anyone with the same predicament.
Step 1: Your materials
58 cement or fire bricks, preferably with the dimensions along the lines of 12"x5"x5"
Steel grating that will be as wide and long as your forge
Air supply/bellows (I used a shop-vac in this case)
