I usually criticize people on here,that have made inferior products,and try to pass them off as something incredible.So it only seems fair that I praise someone for building an outstanding item.......so here is your praise, I am very impressed.It looks like you took your time and patience in constructing this burner,and it looks great,and operates very nicely.Great job,and great video.Thank you for sharing it.
I'm doing a project for my High School class and I am building a foundry to pour aluminum and I really need a torch like this. Would you be willing to sell one or maybe sell just the intake with the brass fitting? I've been looking at a lot of hardware stores and I cannot find a fitting like that. By the way watched all your foundry videos and the end result is awesome.
I like the way you have done it with the gas tube intake instead of a pipe going through end with a hole to put gas into pipe one of the best looking burners i have seen very professional well done. I have seen alot of burners that have cut off valve just before connection to burner thats the only thing i would add so to have for quick gas cut off if need be. but otherwise a really good burner.....Thanks
@agentxoo7 - I put a good bit of thinking into it before I began making parts. One thought was airflow. Having a big pipe running thru the air path is not good. I also made sure the air entry into the intake somewhat compressed the air as it was charged with the propane gas (venturii effect) . The ID of the intake is exactly the same as the ID of the gaspipe. Airflow is 99% undisturbed. When the charged air hits the nozzle, the vent holes restrict backfiring at low operating pressures.
@jameasun: I did experiment while testing, by assisting the air intake with a blow dryer. This disrupted the airflow quite a bit and often blow out the flame. I also tried choking it, and it also dramatically affected the flame. While mounted to the test post, i could only crank it up to about 45psi before it would blow the flame out. Once running (at temperature) inside the furnace, this wasn't a problem.
do you have any plans for it? I'm thinking to make 1/5 scale size and can post a video after finish (=

it looks professional!

It burns a bit too rich on your vid. Try to add a choke at the venturi.
Otherwise, nice design !

What pressure are you running?

@earlyhemibill
I warm up with 18-20 PSI which takes about 20 min (for aluminum)
once it's running, i can back it off to about 10 psi

Nice design. I would like to see what it does with a blower hooked up to it.
