Long time lurker, first time poster....oh that's so lame I just had to say it though.
So I made a small drop point utility knife that I need to heat treat(1095). First I was going to use charcoal...then I played around with fire and an old file....then I started thinking about a 1 brick forge. It dawned upon me that I never let the coals get even and hot...that and a wet hole in the ground made things far harder than they needed to be. Should have bought a chimney with my lump charcoal.
I'm back to charcoal, I think it would be an easier and cheaper setup for me to make. Truth is, I might not use it for the one knife, let alone learn to forge others. I like the idea of charcoal too. The knife blade is about as wide as goddard's one brick forge too.
I'm thinking of a setup similar to a grill. Maybe a flower pot or bucket lined with homemade refractory.
The refractory would be stepped so a grill would fit in a few inches from the bottom. Charcoal goes on top of the grill. Some air holes in the bottom of the container with a tuyere. I was thinking a small bellows would be plenty for this setup....what do you fella's think?
Maybe the tuyere should come from the side and be level or underneath the coals? Like a japanese sword forge.
