Picture of Homemade Forge
Hey guys, today I bring you my step-by-step guide to building your own forge.
A while ago, I decided that I wanted to start doing some more serious metal-working and start in the art of manliness: blacksmithing. My only trouble was that I couldnt find many easy ways of building one, so I began planning and building for myself! Hope this helps anyone with the same predicament.

Step 1: Your materials

The size of your forge is completely up to you, however for my forge, the materials you will need are: 
58 cement or fire bricks, preferably with the dimensions along the lines of 12"x5"x5"
Steel grating that will be as wide and long as your forge
Air supply/bellows (I used a shop-vac in this case) 
Coal

Step 2: Laying your bricks

First thing you will want to do is to find a location to put your forge. Put it in an open space away from trees and cover so your smoke and carbon monoxide can escape easily.
Next, you will want to flatten the ground you wish to use for your forge. You could even get some extra bricks and use them as a foundation.
Finally, based on your plan, start laying your bricks down. For my particular forge, I wanted it to be a pretty decent size, so I laid them so that there were 2 full brick lengths on each side. 

Step 3: Incorporating your bellows

Keep stacking your bricks in a staggered formation so that the forge is stronger and less likely to collapse. Depending on how high you want your forge to stand will cause a variation on where you put your bellow opening. Originally I was not going to have mine as tall as it was, but I changed that.
Once you have reached the 5th layer of bricks, slide a brick over far enough to fit the nozzle of your vacuum in. You may cut the protruding part of the brick off for aesthetics, however I did not.

what about adding a tin roof on top so if it rains it won't put out your fire?

great design but not very efficient i made mine seven sixteen inch long eight inch wide and four inch thick concrete blocks

You might want to look into a smaller overall setup to make more effecient use of the heat that your charcoal is putting out. other than that, a more directional flow of air will help it burn hotter as well.great build though!

Hey I was wondering what kind of Charcoal do you use for your forge. I also am trying the art of manliness and I have a forge similar to this but don't have fuel to make it actually "Forge".

When I fire it up, I just grab a bag of charcoal from walmart, usually the barbecue stuff. Works surprisingly well. Just try to avoid the briquettes and get the lump (the stuff that just looks like chunks of wood)

Thanks!

I was actually planning on taking a pic of my whole work station when I got a chance. and surprisingly, no, the nozzle didn't melt after well over an hour of working with it.
Can you take some picture of the vacuum set-up? Wouldn't the nozzle start to melt if it's too close to the heat?

Have you ever thought about joining the bricks with refractory mortar and thus making a permanent forge?
