Good job! That’s a simple very clean efficient set up. Thank you!
Thanks for the comment it's still working great.
Good call on the mig tips for adjustable orfaces makes changing sizes real easy if you find you want something different.
I think that it will ok will see.
Love it! Great project. I like your style of explaining things.
Thank you my friend.
@@Robinson-Homestead put a shield between the valve and the burners so you won't have problems with the valve heating up
@@mohandarifi7204 thanks for the idea.
Love the air control, great idea and simple!!!
Thanks for watching Irene.
Air regulation not need. Appears to be too rich on fuel. Should be burning two tone blue. The 3/4 × 1 " couplings are need on C3H8 (propane).
I had to chuckle watching you find center on the brass fitting when I saw a mini lathe on your bench.. I've had those moments to.
That's me thanks for the comment and watching.
love the dampers, perfect.
Thanks Mike.
excellent video. Thanks a lot. I am building a Commercial Pizza oven and this is just what I needed to understand how to build a Venturi
Glad I could help thanks for the comment and watching.
great build i have more to watch before i build my own but going to eventually build my own forge for knives and swords
Thanks for watching Tim look at my blast furnace burner you will like it it will work on your forge to sorry for the late reply.
Thanks for the video. I used yours in combination with some of the others. My air intake is slightly different. Plus I used the .030 mig tip in my tubes.
Cool thank for the comment Troy.
Awesome Job Kevin as always, Keep them video's rolling, love watching them

Great job man. I am currently looking to build a torch with a 6 foot length pipe. For a huge bar-b-que pit. This help a lot. Thanks.
Thanks for the comment Chon glad I could help Merry Christmas my friend.
Thank you. Very cool
Ωραίο το σύστημα υγραερίου και το φλογιστρο προπανιου αυτό είναι καλό για χυτευση αλουμινίου σε καμίνι προπανιου .
Neat build Kevin. You saved a bundle making these my friend. I'd call that a real success.
Thank you Dean.
You should be feeding the burners from the center instead of on one side . You will find that with the center feed line you will find that both burners will burn at the same rate .
Thank you for the help Joe.
I just built a double burner and did that. My tee is in the center. Turned out really nice. 😃
FYI,, all you need to do to get your next flat spot to be 90 degrees is just place the first flat surface down on the sander plate. It is 90 degrees to the sand belt surface. Just keep rotating till you have how many you need, 2,3 or 4. o > __l
Nice forge fire Ken.....sure wish I had one of them....Maybe i`ma going to build my own.....CHEERS
Build it with me Gator do some videos I will be there my friend Good luck on that toilet seat looked warm.
good job Kevin like that plasma cutter too.
Thanks Danny Plasma working good I had to fix it tip was plug.
good job man on these burners, I enjoyed your explanation and how you went about it. I was looking on an alternative for my flamethrower pizza burner.
Glad i could help
Damn Mr. Robinson, I believe that's the best burner I've seen so far.
Thank you very much i appreciate that.
Very comprehensive video. Thanks!
You're welcome! thank you for the comment.
Love the video. Nice job. However I have built several of these torches and pairing them up has been difficult because of the flow within the piping. You can see that one of the Torches has a more neutral flame and the other is more oxidizing. The only way I found even that stuff out is to weld up a larger pipe as an expansion manifold, tap it to receive the torch heads, and / or putting a valve over each torch Supply head individually. The other possibilities you have to commit to using two tanks to make the Flames perfectly even. For banging on metal it doesn't really matter that much but for even heat and Welding it's going to make a difference later. But I love the video the design is amazing good on you sir. Other than that have a nice day
Erik, thanks for the tips and for watching.
Why not put the feed tube come in from the center instead of from the end.
@@SC-fj2zp I tried multiple positions on mine and what I came up with was that to make it work the pipes needed to be ported the same way you would if you were trying to make horses power in an engine: porting the heads to keep air cavitation. Pipes that are not machined do not have the same ID around the threads and the welds on the inside also very, etc. these things build resistance in the air flow allowing one pipe to dominate the other.
Another chance that I did was to put a shut off valve on each pipe. That allowed me to regulate the back pressure on each torch. Didn't fix the problem but made it a little better.
The best configuration I found, and made me move away from torches for blacksmithing altogether, is called a ribbon burner. It's a fire brick that has holes in it which has been married to a piece of pipe or expansion manifold. However it does require a fan to supply constant positive air pressure. But I have to tell you it has been immensely valuable. And I'm really glad that I built one of these. The best part is that it allows me to regulate the propane pressure down to almost 3 PSI when the forges up to pressure. To do forge welding I only need 7 to 11 psi. Depending on the time of year.
So in summary: if you're into this then check out porting if you have more money than time, and look into a ribbon burner to save yourself some money on propane.
I hope this was helpful to someone.
Other than that have a nice day.
Thank you so much I'm a metal fabricator and my oldest son is really wanting to get into this and I was looking into building one but thanks to you I'm not going to bother I know what we need to get to get him into it but at first I'm probably going to start him off with a coal setup and let him see if he really wants to do it before spending the money the real deal! But really appreciate the information 👍
great work
GREAT JOB! INCREDIBLE BURNER!
Thanks for watching.
Good work! Thanks for sharing!
Thanks for watching!
good job kevin
Nice job and a very nice result! I like the creativity with the spring held damper. Sure, if you knew exactly how much air flow you needed, that wouldn't be necessary. Most of us that have fooled around with these, however, are not aerospace engineers who can tell you the correction formula to achieve the ideal laminar flow through your bell resulting in the correct turbulation of the gas for a proper mixture. In other words, we usually end with trial and error. I'm sure you will eventually land at a much lower psi, but the burners seemed to work very well when you first turned them on so I think you're fine. Well done.
Thank you for the comment and for watching Schyler Winnen.
Am trying to dispose of about a hundred gallons of waste oil..am going to give this design a go. Thanks for the insparation.
Thanks for the comment and watching Andy
Teflon tape would have been a better choice as a pipe sealant. Enjoyed the vid. I plan on putting dual burners on the forge I'm building. Thanks.
Thanks for the comment Bob good luck on your forge.
muy bueno...muchas gracias desde colombia
Working with gas is at high temperature would indicate compression fittings to be the best choice. Using thread sealer away from the heat source may be acceptable. But I certainly wouldn't use it in the actual burner assembly. And every single valve near the burner should be something from a welder supply.
Thanks for the info Doug.
A fully welded assembly is the way to go i think.
bloody brilliant excellent
Thank you.
very good job
Excellent innovative scientific approach .
Thank you Navin Das.
Great job kevin
Thanks Robert.
Good job on the burners you don’t need that secondary valve in there take it out you don’t need the dampers you don’t need the flamethrower bit all you need is a quarter inch bendable copper pipe plug it on in there put your regulator on it and the shut off valve that’s all you need abusing them both you won’t be using one at a time but other than that you’ve done a good job and stepparents them much it’ll work it always works I would do use day that’ll 30 meg welder tip or 32 not 25 but it’s me but by the looks of it you got a good burn stream and that’s all you need good burn stream the heat the metal up for your Forge good job and if anybody says any different tell them to rub salt good job mate
Hey Tony the Copper would let you more easily adjust your flames closer so they almost merge, more focused heat within the forge? I think if they were closer together it would be better. You’ve done this I haven’t, tell me what you think.
Have you heard of punctuation mate.
Хорошо.
Greetings from Argentina. Excellent video. Can the incorporation of air driven by a turbine be considered?
Excuse my English, I write with the translator.

i think if you don't mind spending money 50 lb. pressure is ok but if you you check most of the ones i see on youtube run below 15 lb. also at that high flow rate you may have a freezing problem.
You are right I turned it down to 20lb or less thank you for your help cockatoobirdman bill.
Thanks again
for all
Thank you for watching
Excelente, muchas gracias. Saludos
Thank you Juan.
Nice job Kevin ! Like the jet propulsion, almost looks like NASA ! Lol. Hay! how about a electronic igniter ? Your probably way ahead of me... Great !!!!
Cool idea Allen
Nice build.
Thank you.
Hey man super cool but 50 psi is way too much. Make sure you're adjusting at the regulator and not at the valves. The valves should always be all the way open or closed. I run my forge at about 8 psi most of the time the paperwork that came with it said 12psi was around optimal/max which unless you're forge welding or working real heavy pieces is just a waste of gas and hard on your forge because you'll melt the ceramic over time. Also I think you ought to try without your air dampers. The more oxygen the more the propane is going to burn cleanly with no waste or residue. Being that you've got an air gap it is going to drink in as much air as it needs without the dampers but there can't be too much. Good luck! Love to see a follow up if there isn't already!
Thank you for all the good info that helps.
Anytime man. I did recently see another video where the guy is using dampers and also talking about what psi he runs his forge. He was talking around 40psi. I'm really not sure why people tend towards such massive pressure. I'm a plumber by trade and most appliances run on 2 psi. Now I will say this had a lot to do with the size of your orifice which should be very small. On my forge they're about the size of a pin. Admittedly I don't know orifice sizes off the top of my head though. Let me know if you give this a shot, how it goes. I've been thinking of building another forge and a crucible but have always been tenative about home making any propane fixture. Lol
Thank you for the help.
Genial realmente muy buen trabajo pero te falta la vecino traducida al español porfavor..
I have the exact same set up as this, but my burners spatter and dont produce a clean burn, I'm not sure how to fix the problem
u did great things bro... keep it up!
Thanks for the comment and watching.

Belle création.. Qui a l'air efficace.
Thank you for the comment.
Keven, I saw a sketch in the video. Would it be possible to get a copy? BTW you did a very nice job on this. Thanks
Great work. Maybe dual is the way to go! I just produced my own forge burner. My video shows how it functions as a forced air burner and it cranks, but I don't think I can get the temp high enough to melt 24K gold. Looks like I may need a second burner. Do you recommend Kevin?
Did you ever get it worked out?
Great job on the video, I am in final stages of a forge using a craftsman 20 air compressor tank w[made by devil bliss] dont u know and I could not make up my mind on if I really needed a forced air type or just your style with dampers[which by the way is a idea im going with] . you had that think really cookin and wouldnt doubt welding temp, nice blue ish yellow tint, was this your final go with pattern kev??
Great build Kevin. Thanks for the video.

Pretty good
Thank you for the comment and watching.
you should of sanded that bell in the vert position then it would have been square with the opening
Thanks for the comment wes Smith.
I think you probably should have removed the galvanization before putting that reducing coupler to the sanding belt. If you breathe that, you run the risk of tin poisoning!
Black iron would have been a better choice.
Lovely flame picture. Impressive!
Sweet setup! Gonna copy a lot of it for mine. Quick question for you: How is the heat-up on that upper valve? Too hot? Any issues so far? Thanks!
Not to hot on the top and know issues so far James.
Better way to layout holes and cuts etc. on a circular part... take a piece of tape and wrap it around the piece. Cut it to length so that it covers the entire circumference of the piece but no more. Now take the tape off your piece. Now you can mark out your 90 degree marks on the piece of tape by simply dividing the tape length by 4, or whatever your design requires. Once all your layout lines are completed on the tape, put the tape back on the round part. Now you have everything marked out perfectly.
Espectacular el video hermano!!!!
Thanks for the comment and watching
Could you list the parts you used for your burners you do mention a few but not all it would be nice to have a list of parts
Great project for 2017 I recently priced steel pipe good luck.
Thanks for watching.
I'm glad that Spongebob isn't there to stop you !!!
Thanks for your comment Tony.
45 degrees the intersection is 90
Good job but when drilling the nozzle for the burner. Drill it from the inside of the plug. That's why it has a dimple on the outside drill the inside.
Thanks for the information and watching.
Good job pro
Thank you very much
好厲害，讚!!
Thanks for the comment.
Hi Kevin,
You did a good job.
a question: how much is the diameter of the copper nozzle in millimeters?
I have not seen from your video if you have also used a non-return gas valve, for safety reasons.
bye, see you soon
Ignazio
I love the commercial but I have a Casper Mattress. similar I believe.
Thanks for watching Daniel.
LOL ok I like your video but that comment was suppose to be for the purple vs. Casper mattress.
I try to answer all my comments Daniel.
Great video, I run mine at 12 psi. Why do you need that "torch handle" just put a short nipple at the first burner and connect the propane line directly.. Good job on the explanations
Look at my gas forge build in my playlist you will like it Adrian thanks for the comment.
Красавчики
Great
Thanks for watching
Add small turbocharge before the nozzle, now it became ICBM.
I am making one for pizza oven but with less pressure and more large flame
That sounds cool i would love to see a video on it, thanks for watching.
I appreciate your tutorial video, I have a question can natural gas be used in this forge?
Not sure on that one Jimmy.
Yes, you just need the hole in the nipple to be slightly larger for more flow.
id stay away from natural gas its more lethal but propane burns hotter than natural gas, otherwise everyone would be using natural, thats the 1st thing I was taught., 2500 vs 1000 thats a big difference.
Great job Kevin I just happen to watch your complete forge video first and than watched this one can you tell me where I can buy a propane pressure Gage I'm running my forge without a gage and would like to know what pressure I'm running at .
Not sure where you can get a gauge honestly I don't know what pressure I'm supposed run mine on JK.
Most welding supply stores will sell them, that is where I bought mine from. I have also seen them for sale online, a good place to start for price comparison. Try ebay as well as many other online shops. Cheers from John, Australia. PS I think I paid about $50 Au for mine.
joandar1 Thanks much appreciated Jaime CT
You are most welcome Jaime, I am happy to hear from you and trust all works well for your tasks ahead of you. Cheers from John.
Hi, please how big holes do you have in this small pins for out running gas? 0,5mm or?
Tibor, If I remember what Kevin said correctly the tips he used were .025 dia. That translates to aprox .55 mm in metric. Hope this helps a little. Cheers from John, Australia.
Not bad, i would recommend removing the galv, with all the heat it will put off some unhealthy fumes.
Thanks for watching.
The width is not important as long as both flames hit the crucible equally for the proper transfer of heat.
And mine is designed like that but have forces air blowing into the burners, so I'm running much hotter.
Cool thanks for watching.
It seems like you took inspiration from Grants Thompson's "Gas Blaster" video.
Thanks for watching Tyler.
Thanks for watching Tyler.
😂
Ingenious, would love to know how they worked out in the forge.
I have videos on them look in my play list Jose thanks for watching.
какой блатной молоток!!!
Good video but i really like your shop. Lol
Thanks 👍
Do you sell these too? Great job
Your modestly shows but I l would be proud to show that burner . When you said you are using the regulator on the second burn , then you began with open gas bottle pressure ?
John, i always use a regulator.
🔥👍
Thank you.
Great design and instructional video! Thanks!! By the way, are you from western Pa?

can we use natural gas instead of propane?
Not sure on that one thanks for the comment.
what tap did you use for the welding tip?
I would have to look I think I said in the video not sure.
great video but did not think about security
Thanks for watching.
Kevin, great videos.
I’m getting ready to build a forge myself.
What kind of brick did you use? Just regular fire brick?
Chad
I just used regular fire brick Chad it is working for me so far Merry Christmas Chad.
Kevin Robinson Thanks Kevin
its not about the pressure. What does matter is the flow rate to handle both burners
Ok thanks for the info D Crawford.
you dont need 50psi.
thats a tad high and you dont gain much.
I do think your right Mike thanks.
the paste for leak seal on the welding nozzles was unnecessary since the Venturi would suck any leak into the air intake and it would burn just like anything else.
Thanks for the tips.
Not to sure on the size of fittings
👍👍👍👍👍👍👍👍👍👍👍👍
Thank you.
Trying to make the flat spots on your pieces 90° off your first one... couldn’t you lay your first flat spot facing down? Then the next face (going against the grinding surface) should be 90° from the referenced face. Right? No need for all the measuring and use of a square?
thanks for watching
Kevin Robinson - My pleasure! Didn’t really answer the question though. 😆
I don’t mean for it to come across rudely if it did. I’m asking out of curiosity, really. Seems like your design works pretty well. Have you altered it at all since your build, finding some things more efficient than others?
@@thecarpenterswoodworker8790 that's okay I haven't altered it at all and the grinding on the flat surface would work fine
How did I receive your response to Kendall?
what do you mean joseph?
