I have just obtained 140 normal orange/red bricks and I want to build a normal coal forge with. But I need some help with the design. Note that around 40 of the bricks are not in perfect shape and may be differ in size. I want the forge to be 7 bricks in length and 4 bricks wide. Each brick is about 25 centimeters long, 12cm something wide, and about 6-8cm thick. This is the best I could do: I the area under the iron bars is for ventilation, where I will have some fan blow in air. So in this area should I just leave it like that or should I make like a maze so that the air will get everywhere or will it be good with just the open area? As I don't have the money to buy a gas oven I will have a hard time with tempering. Any ideas on how I can manage that? Like a pocket or something where the heat won't be so strong or something? Any ideas and suggestions will be highly appreciated, making this forge will get me one step closer to forging!

any perticuar reason it has to be so far off the ground? also an idea i had for air flow was take a metal pipe and drill holes in it all down the length and then hook it up to a fan or air source would that work?

Scrap that idea. Read the information on this website. It isnt the best (the writer has some odd opinions), but it has the basics on it. www.beautifuliron.com/forge.htmYour design wouldnt work as; 1- The coal wouldnt stay on top of the bars, unless they were very fine. If they were very fine, and you managed to get the forge to working heat, they would burn away. 2-The air draught is too spread out. You would not get the coal burning hot enough. A fan would supply insufficient amounts of air. 3-This would also waste fuel, as the distributed air draught would allow ALL of the bed of coal to burn. Hope this helps.

I read some on that site matt, but it didn't help me much, my English is lacking when it comes to terms and such. So I still need help with making the forge!

SL, you are going to want to go with something along these lines I would think, tall long forge, throw a firebrick over the tuyere to cut it down to only a 5 or 6 inch long tuyere for forging the blades, and then open it up and burn the whole channel when heat treating.

I have seen your forge Brenno if you mean the one made of an oil thing? Sam: that picture looks really good, can you elaborate? Thanks for the help by the way!

What Sam says is a great idea. Do that.

The right side picture is a top down veiw, you see the along the length tuyere/air pipe, with the blue arrow being the air coming up out the holes. The left veiw is a from the front as if you were standing at the forge, You see the blower pumping the air up through the pipe into the tuyere/air pipe, and the air coming out the top.
You put a firebrick over the hole about 10 inches from the front of the forge when forging, cause you don't need the fulll length of the blade heated up when working it, only about 6 or 7 inches at a time. You only need the full length for heat treating.
