Well its time yet again to upgrade the forge. I have seen a few videos on YouTube and the forge design that is most common is this one seen being built in this video. My second forge design was simply an oil drip pan with a flat dried mud floor and a pipe with holes submerged in the mud. After rethinking my forge design I re-laid the mud in a V type shape to better hold the charcoal. Now I think it’s time to go bigger and better with a new design. I have this fire pit that I think I can use for the next forge. I want to make the funnel type thing seen in that video. Will it work? How big should I make the funnel? How deep should it be? Would it be better to make something more like a trench? I need a forge that heats as evenly as possible and is as efficient as possible with charcoal. i am open to any other suggestions. edit:

That fire pit of yours could well make a fine forge, but you must line it with a refractory material to stop it burning through. Clay works well. Fire clay works better. Sand can be used at a pinch.
To answer your questions, it should work fine, but I cannot make suggestions as to dimensions as I would have to know how big your new item is.
Your photo of the first forge shows that you are using charcoal briquettes as fuel. Is this correct?
The best advice I can give you is to ditch the charcoal and get some proper fuel. I used charcoal, but yesterday a neighbor gave me a 25kg sack of anthracite coal, and it is a zillion times better than the charcoal. Coke breeze is the best fuel, in my (PERSONAL) opinion. Having now used charcoal, coal and coke breeze, it has been my favourite, and the one I found most pleasant to use.

the fire pot is about 2 feet across, 7 inches deep, and about a foot off the ground.

7 inches deep is ok. Don't make it too shallow when filling with clay. That is a good size for a small hearth. Go for it!

What do you mean when you say funnel? If you mean the V shape bit for your charcoal to sit in, just do it by eye. You've built a forge already, you should be able to guess by now. If you're using clay, you can experiment with different sizes, as if it doesnt work the first time, you can chuck it all out and start again with little hassle.

Ok ok i think we have a misunderstanding here i have 2 possible forge ideas both seen in youtube videos. Here they are which should i use? Are there any changes that need to be made? Sam, I'm sorry but I just don’t think that spending 30+ dollars on a video to answer a few questions that can be answerd here is the right way to go.

Do both. Your frame looks to be big enough for it.
Nothing says that the firepot HAS to be dead-center in a forge so set each one side-by-side, put your air service for each on opposite sides of the forge, and make your forge bottom flat enough so that you can use either one.

You'll keep having questions until you spend the money and get some nice instructional material. I don't have the video, but I learned most of what I know from books.
It is 30 bucks well spent. Don't cheapskate!

I have to agree with matt and sam, get the video at some point at least. If nothing else, it'll save you valuable working time and save you money in the long run. I'm going to check it out myself.
As for your designs, they look workable. Personaly, I would go with the trough model and lay two air supply pipes side by side with about two inches between them, holes drilled to point towards the opposing pipe at an upward angle of about 45 degrees or higher. It was just an idea that popped in my head when I looked at your plans. Also, are you working outdoors, and what types of blades are you planning to make ?
Best of luck !

There is no need for 2 pipes, one is more than sufficient.

It was just an idea to get a more even flow of air through the fuel and keep cold spots down to a minimum, which I hear is often a problem with open air forges. I'll be posting my own forge designs soon enough( after I've tested them, of course ) In this case, one pipe should be sufficient. Also checked out the link you dropped, sam. My thanks, I'll be grabbing a copy soon. By the way, aren't this couple members of the neo-tribalist guild ? I think I looked at another page in the past that showed their adobe forge and improvised anvils. Darkslyde, go with the single pipe design. It'll be enough for this application and would be easier to construct. I just wanted to share an idea that hit me, since I'm always looking for ways to improve on things
