The opening for the gas is fairly large; 1/4" maybe? The overall design is based on the hand drawn plans given out by Jerry Culberson at his course at Old Cedar Forge. I guess I need to start playing with that end if I want to achieve more control over the fire. I forged tonight for almost 3 hours. I did increase the gas pressure a bit and decrease the air flow which lowered the overall temp a bit but I'll figure out something for the gas pipe to reduce the output hole.
I have a 25gal. propane tank that I use and with the old regulator it would still start to frost up as it got empty. With the old regulator the flow would decrease after an hour or so even with a full tank. Depending on how much or little the volumne decreases as the tank gets empty using the new regulator I may spring for a second 25gal. tank and use them in tandem.
