A small forge for Blacksmiths, not a forge for small blacksmiths.
A long-term goal of mine's been to have a forge small enough and well-mannered to keep in my suburban garden, so that means no bituminous coal. I considered a Gas forge but when that turned out to be impractical for the scale of work i want to do, i looked elsewhere. Plus, with a gas forge i'd probably have ended up blowing my legs off.
So, suburban (so no smoke) and i can't use gas.... the only alternative i could see was charcoal. Finding a lost middle-american civilisation in among my socks would be considerably easier than finding the kiind of charcoal i need in the amounts i need. -everyone wanted to sell me a few tons at least-
Eventually, i found something called "smokeless fuel" seemed to be pure carbon or something, so because it was only Â£1.75 for 10 kilos i decided to give it a try...
Step 1: Find Something to Make the Forge In
I WANTED to use a wheel from a car to do this but i couldn't be bothered going all the way to a place to get it only to carry it home and eventually set it on fire, so i looked closer to home. I ended up using a 12 inch stainless steel cake tin. I never once thought i'd be making a forge in something that vould have been used to hold cakes but it worked really well.
The first thing we need to consider when building a forge is the ariflow. Too much and it gets far too hot. Not enough and it doesn't burn at all. To get the air into the forge, we need a hole through which we can out a pipe. Wheels come with ready-made holes. Cake tins do not. Ergo, i had to make one. "It's only thin steel, what can possibly go wrong?"
I spent something like 40 minutes getting a hole big enough to put the pipe through. SO: this step's instructions: Through Fair means or Foul, Make a hole big enough to fit the pipe through. Make sure the pipe doesn't go too far in or not far enough in. about 1.5 inches was right for me.
