Title: Help, Iím trying to make a gas burner.
Post by: Ed Brooks on March 30, 2019, 07:16:25 am
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 10Ē of 3/4Ē pipe.
Iím going to be putting this in a very small forge, I plan to use it for small to med knives. Thought Iíd ask before I buy the parts Iím 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.

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

10Ē- 3/4Ē 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 20Ē 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. Itís 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"

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?

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
