Ahhh...I used the diameter instead of the radius...my bad...thanks for the correction...That changes alot. I've been reading that a 3/4" burner works for 350 cubic inches...I thought I was much closer...good catch... I did begin the burners 101 thread...not quite through it yet... Thanks guys...I promise the posts will get better!

Hey all! I am building my first forge. Basically a 2" diameter hole between 2-9" soft fire bricks. The forge will be about 113 cubic in. Mostly, I'm planning on heat treating small knives. I have access to a larger forge, but it's a bit of a drive from my house, so I wanted something small to make working a bit more convenient. Originally I was going to use a Mapp-Pro gas setup. As I've been doing my research, I'm wondering if a small venturi burner might be a better solution. Can someone help me get the right size venturi burner built? Thanks in advance for all your help!
