I've seen a couple of designs so far on using fire brick and a propane or mapp torch inserted into a hole in a chamber formed by just one or several of the bricks.
I'm wondering how problematic having the flame from the torch entering one spot is, and if you're just supposed to move the piece around and try to heat it evenly, or wait for the whole chamber to heat evenly or what.

This one here seems to be small enough and simple enough for me to build, but I still wonder if the part where the flame enters will heat parts unevenly. Though that's more of a question with gas/torch powered forges in general than with the fire-brick ones. However, since I like the design of this one, I figured I might as well be specific and ask about it.
