Hello, this is my first time posting here. I started forging about a year ago and I decided I needed a better forge. It is all 1/4" steel, 4" tuyere with 2-1/2" inlet. The firepot is 11x6x5, don't know if that is too big. Trial and error for the first build I suppose. Still have to make a lever for the air gate. I will be using coal as coke is hard to come by in my area. Any advice / criticism on improvements / upgrades would be appreciated.
