Thank you I would have never thought of that 

Hair dryer might work. I was looking at some bathroom fans on Lowe's web site would those work? If so what cfm should I be looking at getting.

I live in the Redding, CA area... 

I'm in need of an air sorce for my coke forge. Right now this is the best picture I have. The fire pot is about 8 inches deep and 10x12 at the top and about 6x8 at the bottom I'm going to be modifying it as I'm having some issue with melting fire brick. The pipes are 3 inch black plumbing pipe. This was constructed on a budget and all metal is from the scrap yard of my local steel shop. Right now I'm using an small old shop vac but that seems to be too powerful as it's burning steel before the whole piece is hot. I'm just starting out and I'm interested in all aspects of black smithing/ knife making. I have watching countless hours of YouTube videos but haven't found exactly what I'm looking for nor the user feed back/ advice that I need.  Thanks for your time
