My first fire in a forge was rather memorable. I had had been lurking for about a year when I decided that I had enough info to actually make the effort worthwhile. So I rigged up a forge out of the bottom of an old drum. I bought a small shop vac that was on sale. It was all I could afford, I hoped it would be enough. I stoked the new forge with 10 lbs of the Kingsford edge and let it coal for a bit. Now when I flipped the switch for the shop vac I learned a lot about forges and forging very quickly:
1) outside is better than inside for experimentation
2) Yes a shop vac, even tho small, is sufficient to power a forge
3) the concept of a choke plate suddenly focused sharply in my mind
4) Flames grow larger as you add air and can get as high as the garage door that is over the forge
5) Briquettes sound like Rice Krispies but feel like biting flies
6) they also make a LOT of ash, kinda like a volcano
Lessee, that is about one second per lesson as I figger it.
Annealing a piece of steel is pretty straightfoward, get an amount of vermiculite and let hot steel lay in there for a while. Since we had a couple of bags at work that were to be disposed of I glommed on to the opportunity. I let a coworker have the bigger bag and I took the smaller one, that the label was illegible on. After carefully forging some coil spring and rather than opening the bag completely, I merely shoved the stock through the paper and went back to forging. Over the next several hours I kept smelling something vaguely familiar. When I saw the smoke rising out of the bag, "I thought vermiculite was inflammable" went through my mind.
I tore open the bag shook it out on concrete and poured dippers of water on to it. That is when the odor hit me that I had been smelling all evening, Chrome Ligno Sulfate, a drilling mud additive. Sure makes things slick and slimy when it gets wet. Clean up took about an hour as I went through all the burning crud and put it out. Threw away the remaining dry stuff in the bag, slopped the wet goo on top of it and felt awfully good about my thouroughness.
0200 hrs and I am answering the phone, my frantic neighbor is telling me that the house is on fire! I blaze out into the nippy fall weather to get my hose and put out the blaze in the large plastic trash can on wheels. The hose was inside the garage so I turned around to get it.
I can safely recommend to you fine gentleman that when you replace the knob on a door it should NOT be one that will remain locked even though it turns easily in your hands.
After arousing the Domestic Goddess by my incessant knocking on the front door I go into the garage again, get the hose, go out side to put out what remained of the fire. Fortunately it is a brick house and nothing caught. While using the water hose my feet got muddy and cold so I went to get more clothing and, you recall the door knob I warned you about? Finally got everything done and back in bed by 0330.
