I am cheap, just like Isaiah.
Most of you will notice that this is a version of Tim Lively’s “wash tub forge.” I made this forge in a 5.5 gallon oblong galvanized steel wash tub. The tuyere is made of one inch black pipe with 1/4 inch holes drilled every 1 inch. The refractory that I used isn’t actually a true refractory cement, I took a 60 pound bag of quickrete and added several hand fulls of wood ash. All of the parts cost me about $35, it is probably one of the cheapest forges that you can make.
The forge has worked very well for me so far, It has develped a couple of cracks in it, as you can see in the photo, but I think that they are natural. This forge burns about 4 pounds of my homemade charcoal per hour, while maintaining forging heats. The washtub forge is able to to get sustain forge welding heats with ease, though flux will fill up the tuyere holes really fast. Most of the time this forge is too large for the things that I make, so I simply choke down the size of it with some clay. I can mold it into what ever size or shape that I want. I power it with an old hairdryer, though most of the time I find that the blast is too hard.
If I were to remake mine, I would have made it into more of an oblong bowl instead of a slot.
I would recommend this forge for the beginner.

Edit: wow, I didn't realize how much my forge was like Isaiah's, the are practically the same forge.
