I tried that for my test burner but never was able to sustain fire. I found a brass 1/2 inch NPT to 1/2 inch hose allowed the 1/8 inch brass fuel pipe to pass with no slop. I planned to solder it when adjusted, but I think my regulator was bad and have since replaced it (without retesting this design). I felt the design was complex and heavy, so I decided to take it apart and start over.
I am building three Reil style burners using a slotted pipe nipple to hold the fuel tube in place and axial chokes. My forge body will be a 16 gallon drum with 3 inches of ceramic wool insulation. I just am unsure of what size MIG contact tip to buy for 3/4 inch pipe, and what thread is on said contact tip.
I pilfered a .030 from my dad's spares for his Hobart welder, but it appears metric...
