Am new to the forum. I have been coal blacksmithing for a few years, but have been using an original civil war mobile side-draft forge all this time. Now I am setting up to work at home. A friend gave me a 18" x 20" cast iron pan with 2" tuyere in the bottom stand has 4 metal legs. I have a 3" Buffalo Forge blower. My question concerns the lining for the opening. I have fire brick for the pan, but do not know if I should line the bottom over the tuyere?
