Help, I’m trying to make a gas burner.

[Ed Brooks]

I have a BBQ valve with 1/2 psi. Do you think this is big enough for the job? Or will I need more gas flow? I plan to mount this on 10” of 3/4” pipe.
I’m going to be putting this in a very small forge, I plan to use it for small to med knives. Thought I’d ask before I buy the parts I’m missing.
Thank you. Ed

most venture burners use 20-30 psi  regulator.
10 inches of 3/4 black pipe is too long.
ive built a few burners and 8 inches seems to be the magic #.
use a .035 mig welding tip for orifice.
or p.m me your address and ill send you 1.

When I built mine everything I read said that grill regulators wouldn't work very well.  I ordered a regulator and hose off Ebay.

[Ed Brooks]

Thank you for the replies. I thought I was on to something with the dead bbq. I’m glad I asked before the build. I’ll be shortening the pipe as well. I appreciate the kind offer for the tip, but I’d hate to take it when I believe I have a tip. Thank you!  eBay great idea,
Thank you guys. Ed

10”- 3/4” for a gas burner is just fine. But I agree getting the proper regulator could make all the difference in having eyebrows and not lol
My smaller forge gets used quite a lot more than my 20” forge and it only cost me about $75 in materials. More than half was for the burner.
Few pieces of all-thread, angle iron, some fire brick, and a single burner. It’s been plenty for forging hunting blades and broad heads, even making up Damascus billets to store away for later.

I use a small two-brick forge for more than 90% of my forging.  The burner for it is a Mag Torch large pencil tip torch head.  I've had people tell me this isn't enough heat to do anything, but I can do a whole lot with it, actually.  Built it to tide me over until I had a big forge built, but that big one only gets used for large projects or straightening steel.

I've got a video of a project up on YT and there's a good shot of the forge in the bit about heat treating at the end.

I can make and heat treat a 6" blade with this little forge.  It may be dinky, but it isn't a toy.

You don't always have to make a big burner.  I got mine from Amazon for about $20.

Super easy to build, 1-1/2"-3/4 bell reducer , 10" 3/4" nipple, and another bell reducer. One 3" long 1/4" nipple, coupler and cap, and a .035 mig tip. Drill and tap the 1/4" nipple for the mig tip line it up centered down the 3/4" nipple and tack in place . I used gas rated Teflon tape the yellow one, the reducer at the forge is 3/4"-1"

This forge gets to forge welding heats pretty easy

Why is the pipe so long from the forge to the reducer? How do you control the airflow on your's, others I've seen have a sliding plate on the reducer?

[bubby]

DC I built this from a YouTube video and I don't have all the answers for your questions. I built several different ones and this simple one worked the best, has been very efficient and suits me. All I can say if it's not complicated enough build one that is lol. I like the kiss system
