What is a good size length and diameter pipe to use for my venturi, I am using an old propane tank for my forge. What is also a good starting distance from the end of the pipe to start my dialing in for it. I have also seen some forges with the pipe aimed straight down and have seen some offset (for heat circulation I guess), any pros/cons to either way. I am using a .025 welding tip for my knozzle. Any help is appriciated.

I got it working, I had a high pressure reg at the house, just had to buy the adapter for the tank, I am now able to hit up to 15 psi. Ran it at 2.5 psi while I adjusted to venturi. I need to insulate the forge now and will be up and running. How much morter do I need to buy for a forge made out of a propane tank forge. I am going to have 2 inches of kaowool to make the inside area a little smaller?

I have started building a venturi forge and am unable to get enough pressure. I have seen that others have 2 1/2 PSi to their system. I have a brand new propane tank, pressure regulator. I come out of the tank into a new regulator down to a 3/8 inch ball valve into a 3/8 "T" with a 15 PSI gauge then into my venturi tube. I am not getting any reading on my gauge, but get a little gas out the venturi. I tested the gauge and it works, I can blow into it and read about 2 psi. Is there a special regulator I need to buy, I have tried 2 different tanks and 2 different regs with the same results. any help would be appriciated.
