Thanks for all the advice I've ordreed parts and settled on a plan just have to actually get to building it.
https://www.youtube.com/watch?v=YzZmnY0in6k&t=59s the guy in the dvd has a part by part list on his website, and I will have to order the burner parts so wanted to check that his will meet standards. Or tweek his plan as needed.
He also has a forge designed out of a propane tank that should be ok when transfered to my air tank?
