The area should not be out in bright light, for the colour of the metal tells you what temperature it be, and lets you know when to hit and when to stop. Colour is essential for tempering too. Think of where the smoke is going to go... Some books show how to make the forge from junk such as old car tyre rims, tins, etc. I have seen advertised in magazines books of plans on making stuff from junk, forges, etc. You should also read up on firemaking, and fuels. Charcoal is the oldest period fuel, but modern smithing uses coal dust - roughly pea size -(low sulphur coal) which is mixed with water to create "breeze" in the heat of the fire - which is coke. Charcoal is wonderful for welding, but less easy to use for other purposes. Breeze is best for all round work. You can use dried hardwood (chips) too, you need to charcoal the stuff as you go, and it is easier to make the charcoal first. Lighting the fire is a skill better shown than talked about, but if you experiement carefully, you will find a method that works for you. Slow small fires are the best to work with. Hitting more air for the purpose will turn things white hot in seconds. The manual bellows is a sound practice, beter than a mechanical blower, for when you stop blowing, the heat drops instantly, also saving duel. You need a controlled path for the air, which is called a tyure. Read up on it. You should not have more air than you need, for you just waste fuel, and cool the fire. You can make a "hole" in the fuel, or you can "tent over" and make a more covered in space. Both have their uses, experiment slowly and carefully. the tent is better for welding. The depth in the fire affects whether you are in the oxidising or reducing zone. Read, read, read.

Controlling the air path is the essential element of fire handling, I build a deep fire putting a considerable amount of coal or coke between the air source and the work, this produces a heat rich in carbon and carbon dioxide. This is the same method used to prevent excessive scaling in modern atmosphere furnaces used in modern heat treating. This type of fire is called a reducing flame.

The fire pot is just a wooden box set down in the table. Of course, there's about a 4" layer of clay or clay and brick over it. After about 12 hours the clay (through gaps in the planking) is warm to the touch. If I had heats for more than 12 hrs, 2 days running, I'd use a different construction. I don't, so this is fine for me. If you use a pressed steel BBQ or something like that, line it with mud. If you're worried about cracks, mix straw in the mud. If you're going to use charcoal, send the air in from the side. If you're going to use coal, send the air from the bottom. If you like doing things on the cheap, you can build the whole thing from mud & straw. If you'd like a better lining with the mud&straw thing, mix 2/3 sand and 1/3 mud and plaster it in for a lining. when it gets firm to the touch but still damp, build a nice fire and heat up until the lining glows red. If you don't mind bending over, just dig a pit and bury a pipe to put air to it. A forge shouldn't be a problem. Bellows -- I use a shop-vac with a motor speed controller. Junked hair dryers work, too. Have a friend who uses a light dimmer, but it's not as controllable as the motor speed controller. Have used an electric blower on full-speed where the output was blown from one pipe to another. To reduce air, slid one pipe to the side so not as much air went in to the fire. Have a couple of hand-crank blowers around, also. These things tend to come to you after you get going. Have plans to make a set of double-acting bellows, but lack time to get it done. Basic advice: Improvise. Use your imagination and ingenuity. If you're going to do much smithing, you'll be needing every bit of ingenuity you can come up with. You'll need to be able to figure out what tools you need, then make them -- perhaps making the tools to make them. Keep alert, try to learn from mistakes (no, you can't make a frammis that way, but it'd be a way to make a doohickey) and ask questions. Don't look for canned answers. If you ask me to teach you soemthing, I will. Remember, it's my way of doing something. Yours will probably be different and better for you. Learn my way, Joe's way, Sam's way and evolve your own way. When Nick shows you his way, you may change your way. Good luck, and godspeed.

Natural gas can even be used as can diesel fuel...IF you have the correct burner and carburation.

Is forging metal significantly different at high altitudes, compared to low ? Dry air as opposed to wet ? Just curious ... Yes, there is a remarkable difference between altitudes. The higher you get the less Oxygen there is and hence the cooler the fire burns...then you need a recuperative burner that preheats the incoming air to compensate for the lower temperatures,,,, I could get into BTU's and Thermal Conductivity and all that but you would only get lost unless you are very familiar with this sort of thing.... In a nutshell, a gas forge that is regulated and carburated for burning at say 2350 F at sea level will need to be recarburated at 5000 feet above sea level in order to get the same temperature....

I > work in a welding shop and have access to all kinds of metal and tools. Well if you look into your basin you should see a hole in the center. This hole needs something to stop the coal from falling through. I agree with Lady O'Ceo that a clinker breaker is next to useless. A clinker breaker is a three sided piece of metal that would be placed in the hole and attached to a rod so that it may be rocked to allow some of the fine coal/slag out. Not always a desired option. Far better to get a piece of flat plate to cover the hole. In this plate drill holes to allow the air into the forge. I am assuming the set up of the blower is standard where it forces air up through this hole to fan the fire. Below this hole should be a length of pipe vertical to the ground. I am not sure on how much of the forge is missing here. From this pipe at 90 degrees is the inlet of the blower hose. At the bottom is a cap whether it slides on with a hinge or screws on. This cap stops air from going out that way and also stops ash and slag, etc from falling to the ground. You should empty this pipe daily, which is why I prefer a sliding lid. A clinker is a build up of gunk in the bottom of the forge and sometimes has to be removed as often as once an hour depending on how you maintain your fire. This is easily done with a poker and a shovel. Slide the poker along the bottom and once under the center of the fire, slowly lift it up. You may see a large mass all stuck together. That is the clinker and it will lower the temperature of the forge if it is left in.

When I started blacksmithing these sold for $25 each! Now a good anvil is a bit harder to find and a great deal more expensive. Fortunately a forge can be easily made. I have constructed several. The last from an old incinerator. I simply raised the fire box from the bottom to the top and lined it with castable refractory to form the duck's nest. This is a concrete like substance which is available from refractory brick suppliers. You can't use regular concrete in a forge since it will shatter due to the heat. I used iron pipe for the airways. A regular building brick (the kind with the holes) will suffice at the bottom of the duck's nest to support the coals. Most old blowers will work. If you use a vacuum cleaner though don't let just any SCA idiot hook it up. I had a guy helping me once. You know the type, lots of enthusiasm, no common sense. He hooked up the vacuum so that it sucked rather than blew. I was looking at the fire and it was most strange. It was glowing bright yellow, but there was no smoke. Then I glanced at the vacuum cleaner and it was smoking like a locomotive and its hose was melting! Hot damn!

Start with an old grill, take out all the grill parts, if it's gas, set a brake drum down in it (you may have to reinforce the bottom, if it's flimsy), set up a flange, a pipe down, a T-fitting, and another down pipe and a pipe out of the 90 degree angle, use an old vacuum cleaner motor or a blow dryer for the air input (you'll likely hafta set up gate to reduce the air flow if you use any sort of power blower) and a cast iron shower grate (easily acquired at Home Despot for about $7). Keep an empty coffee can under the down pipe to catch the ashes, and always use hardwood charcoal rather than those worthless briquets, and you're in business. A tree stump for an anvil stump and its associated anvil (cheaply acquired, if you use a piece of RR track) can be quickly covered with a small tarp of a blanket, your tools can go inside the grill once it's cool and closed. As far as your hand tools, you can start out with a pair of vice grips or channel locks until you make yourself some tongs, and a ball pein hammer (1 1/2- 2 lbs) will work until you can figure out exactly what you want for a hammer When you're working, you have the basics of what you need, when you aren't, everything is pretty well out of sight. OFC- a charcoal forge like this can easily be used for cooking food as well as steel, as long as you don't contaminate it with brass. toss a small grill over the firepot, throw a steak on the grill, and DON'T fire up the blower, and you're in business. As you may know, I usually have my coffee pot mumbling away on the side of my forge, and at events I cook my meals on it, using my wok and/or pots and/or various bits of scrap bar stock to hold the food where I want it.

And the brake drum is not "just to fill up space", it's there not only to handle the temperatures that a forge can generate, it's to shape and direct the fire, so that it's controlled. I suspect that if you proceed with your cat litter intentions as you stand, it will work for a few uses, and then the entire thing will burn up, because the litter will crack, catching the shell of the barbecue on fire, or maybe melting it, if you're lucky- cat litter just isn't designed to deal with those temperatures. Myself, I'm lusting after some castable refractory I've found that's good up to 3000 degrees Fahrenheit, for the forges I want to build. Fire brick will work, too, although for higher temperatures, you want the light weight stuff, that feels like a bit of foam, almost, when you lift it, rather than the heavier fire brick that feels sinilar to building brick- again, the lighter bricks are resistant to higher temperatures. The thing you need to keep in mind that if you'll be using charcoal for your fire, you want a fire that's deeper than you'd have for a coal fire. Part of what you're doing is focussing the fire with the blower and the shape of the fire pot, rather like what you're doing with a glass lens when you focus the sun's rays to catch a bit of paper or wood on fire- you can get forging temperatures by burning your house down too, but that much fire is a bit difficult to get close enough to use, never mind being a bit inconvenient, when you try to go to bed that night ;-) Phlip Date: Mon, 18 Oct 2004 00:12:32 -0400 From: Bill Fisher Subject: Re: [Sca-cooks] Charcoal forge suggestion ;-) To: Cooks within the SCA I made a forge at my Dad's, when he had his shop. out of clay I found on premises and an old duck egg tuerere(sp) and some angle iron I welded together. I built a wood fire and shoveled the coals into the forge (which I think I had lined with wet large leaves to keep the coals from biting the walls) to harden the surface, and let that go for a few hours, then let it cool.Then I built a soft coal fire, and used the bellows towards the end, then let it cool, then a coal/coke fire and let it cool. At least that is what I remembered doing, it was over 10 years a go that I did it (I think 14 maybe). My Dad disassembled it when he closed the shop, he had used it regularly over the years as a barbque when he lived in the attached apartment. He would turn on the blower for that "steakhouse salamander" effect. He said the clay was fired through completely and had to use a sledge to get the tuere > The thing you need to keep in mind that if you'll be using charcoal for your > fire, you want a fire that's deeper than you'd have for a coal fire.

That would give him a deep, smaller, and concentrated fire. It depends really on the size of his project. I think you could arrange firebricks that way (with some cutting), or clay.
