My brake drum forge seems under powered. It struggles getting the steel hot enough. I'm not sure if the problem is not enough air, too small a Firepot, or that I'm using charcoal. Maybe is a combination of those.
It took all afternoon to make a few nails, and it was hard to get 3/8ths square past cherry red. It is outside under a tree so sometimes when the sun is coming through the trees it is hard to tell.
Here are some pictures so you know what I'm working with.
