Hi there!
I'm a beginning blacksmith, I found ODBSA last spring and started attending the meetings. I've seen demonstrations by Charles McRaven, Dan Easley, and Elmer Roush, had a day of hands-on instruction at a coal forge, and set up a small forge of my own. At my forge I've made a hook, a hot punch, a few knives, started on a pair of hinges, and a pair of tongs. I also got a few hours in at another coal forge at Danny Ward's Farrier School earlier this month (ODBSA "Challenge"), and made another partial set of tongs.
I use a box bellows (first thing I made for it) and my forge is just a bunch of firebricks stacked up. I tried hardwood lump charcoal but couldn't get much heat without a lot of popping and throwing embers out. I found that chunks of wood worked as well or better. Through experimentation I've started using a chimney arrangement and adding the wood (now using bull pine) chunks at the top so they're charred by the time they're in the actual firebox. I haven't been able to achieve more than bright orange heat but that's OK for now.
The anvil I'm using right now is not very good, a piece of rail that was given to me. It had a flat sided "horn" cut on one end which I rounded up a bit but would need a lot more work to be really useful. Too much of the bottom flange was cut away and the top is rounded off to one side since it's used rail. I'm looking for a better anvil, thinking about buying a 286lb Euro Anvil. That would be my first real investment.
Here are a couple of the (rustic) knives I've made, both of these came from a spike. The smaller one has some cold shuts (from the head of the spike - DOH!) so I didn't bother to heat treat it, it's a "letter opener". I did quench and temper the bigger one, so I can test my work. I'm working on a larger one from a whole spike for a friend. All of these balance at the junction of the handle and blade, although I didn't test them until they were annealed for sharpening.
Thanks for the forum, I'm sure I'll be learning a lot here!
Good Luck!
