Frosty lol thank you very much. I'm just applying the simple physics I know from the automotive end(same characteristics) Air fuel ratios, angles, diffusers, bellmouths ect... just looking to make it less turbulent going into the chamber and coming out the holes. I was reading that it is 9 times whatever the diameter pipe is for the length of the are fuel pipe going to the burner. I'm pretty sure I can cut that down to half or less with a static diffuser. I see a lot of guys live in Alaska and don't have access too many parts so I'm sure this would help them immensely. Like I said I'm just messing around with a few things actually using your idea with the wood block. If I think anything looks improved I'll let you know. Once I get to actually use the forge that's when I will look like one of the greenest greenhorns around. That's when you'll get your noob questions.. lol
Steve thank you very much I appreciate it. As soon as I start heating Steel I will have a million questions.
