Unfortunately I ran out of money before i could finish the forge, in total it should cost around $ 50 USD depending how fancy you want it. The plans you will see are paint mock-ups from my actual design, i do not own a scanner so I had to make pictures.
This is what the finished forge should look like
Step 1: Why a forge and getting started up
As a begainner at Blacksmithing they recommend to build a forge out of a Brake Drum I decided against it because I really didn't want to be using a rusty piece of junk to hold 3,000 degree charcoal and white hot iron.
So i asked the guru guy a lot of questions.
And I made plans on it
Basically its fire brick in a square pillar shape stacked like a brick wall
