Ok, got a few more things figured out.
In talking to Jude, I am looking at having the whole system ready for a full blown metal pour during mini-maker faire. Given the drop dead date of april 14th. I think the project is totally do able.
found plans for 3/4 inch venturi that work well with a modification of the gas tip. so this is the way to go. its well documented and 100's of them have been made.
I need to make 7 total (2x burn out, 2x kiln, 3x melt) out of 3/4 inside diameter chrome-moly pipe. with 2 inch venturi flair.
the mod is to add a propane tweco t14 gas tip. this creates a far more stable gas flow than a simple pin hole.
