Hi everyone,
I have done a ton of lurking, searching, and general google searches and up till now Ive had no luck with my question. I have a forge I built before I retired it is basicly a square box 24" X 24" and 4" deep. The air feeds from the bottom via a 6" pipe and a squrill fan repurposed from a central air unit. I can post some pictures tommorow but its already dark here. My question is; because I went a little larger than i needed to on the actual box size would I benifit from using clay or refactory cement to form a smaller more concentrated cone in the center of the forge? I have looked at a ton of designs both flat bottom boxes like mine and the traditional more cone shape. Think it's worth the time and effort? It works great now as is. I just can't help but wonder if I am mising out on something even better.
Thanks in advance for any advise.
