I’ve watched so many videos on forge burners, and yours is the one I’ll probably be replicating. Efficiency is key
Dude got some skills.
probably someone else commented the same things.. i didnt want to check coz im lazy.
1st. i've never build a forge. what comes next is what i've been picking up from reputable sources. as long as this is clear ...
2nd. you want to put a solenoid valve to the gas, which will remain open as long as the fan has current. if the fan stops, you dont want gas flowing into a super hot enclosed enviroment.. neither you want gas running free in the shop
3rd. you can improve the mixture even further by putting a twisted (spiralled?) sheet metal inside the horizontal pipe. this swirls the flow to create a better mixture. i'd recommend stainless steel.
4th. the burner you've made is good. but it is better to use squared one thats longer. this way you don't have a very focused heat source.
5th.. you can run that thing on natural gas. (you do need good gas flow. 1" gas line might be required).
shit sorry... GOOD JOB! congratulations!!
I'm very impressed with this design man. Going to build a new forge in the next month or so. I will build your forces air burner for sure. I'm becoming quite a fan because of the way you demo, explain and teach the fundamentals.
Goodonya Paul!
I’m definitely going to build one. When construction slows down I’ll be blacksmithing. You inspire me. Thank you.
Awesome vid. I have all my parts ready for assembly! Thanks Paul, really enjoy your instructional vids. Lots of Knowledge gained every time I watch.
Thank you for sharing. From all the ribbon burners that I have look in the Internet, yours, in my opinion, it is the most practical, easy to build and very neat job, with a very clear video. Have a nice day.
Great burner and video. I am 36 and fairly safety conscious after spending years working on building sites doing silly things that I wish I hadn't. I would recommend you using ear defenders for nearly everything you do in a workshop; even ear plugs are better than nothing. Another thing MASK MASK MASK, you only get one set of lungs. Also your blower should mounted above your propane inlet (the configuration is right just extend your first pipe off the blower to make the blower higher than your gas inlet) If you lose electricity without realising, your blower will fill up with gas (gas being heavier than air). When you turn it back on........Kaboom, a nicely heat treated blacksmith!!!
Just wanted to say thanks, that burner works really good. Thanks again.
Awesome Job Paul!
Nice video Paul. Will work on this project to build my own forge your style. Great design by far on UA-cam that I've seen. Thanks for the inspiration
After more than a year, how is the 1/4" plate holding up to the heat?
I'm curious too. This looks very efficient, only I've lost cast iron flares in the past due to heat buildup+oxidation.
I've ran mine for about 6 months using a1/16" thick strainer screen. I figured it would melt with the first burn but surprisingly it's still holding up.
Very cool. And informative video! Thanks!
One of best forge builds ive seen, very simple and effective design thanks man!
Glad you like it!!
This is a great build man.
Nice build and love the map on the wall!
very nice man sweet
Thanks again Paul, you are wise beyond your years. I’ve had same problems with low heat. I’m going to use this idea. My press is coming along great too.
Thank you!! That’s awesome and keep me updated on the press!
Perfect, lot of good information
Alright my ribbon burner done! Thanks for your instructional videos.
That’s great!
Congrats
Ive seen several forced air forges now, they seem miles ahead of the standard I made last year.
Many thanks for the build and show.
Thank you!!
In a word it is stoichiometry. The precise mixture of molecules to make the ideal chemical reaction. Adding more oxygen to the propane allows a better fuel/air ratio. This is why many forge flames exit the forge while still burning because that is where they are finding the oxygen needed to complete their chemical reaction in the burning process. I'd suggest remaking the ribbon end with refractory cement as the steel will wear out quite quick and possibly melt at higher forge temperatures. Great build though. A very simple and effective design.
Hey Paul, I just watched your video and I think this is the best burner that I have seen and I will be watching more of your videos for sure, keep up the good work, Dave
Thanks Paul I am currently building a double burner forge and this was very inspiring
I’m glad you liked it!! Let me know how your forge turns out
Thanks for good advice Sir
I use step drills in my drill press, most awesome bit ever invented!!!
Why is it running hotter? Better atomization leads to better combustion. The Fuel air ratio is the key. Forced air ensures good turbulence and a proper fuel to air mix. Nice job on your build. Thanks for the video.
Excellent build, my one recommendation as a welder is to either weld those vertical sections traveling upwards or to turn it on its side and do them in horizontal.
Every welder is better than the other welders.
Thanks Paul a pretty good video,
I would think you'll explain why you drilled and came up with how many holes for the burner head, I am being told that is important information.
Lots of good information to you are helping me and others with our build . Good welding skills, mine are ugly but good enough to hold.
Thanks for showing and teaching me and others Sir
Made one of your ribbon burners for my forge, made one change. Used 2- 6 in.for vertical with cupling drilled n tapped for 1/4 pipe put cape in cupling can change hole size if you want to
Paul, he visto unos cuantos videos sobre fraguas y tu idea es excelente, lo mismo que la realización. El forzador de aire hace muy eficiente la mezcla. Exitos. Saludos desde Argentina
Very good design. I have used it to make many of them they work great
Mr. Pinto congrats at forge and fire, have a nice and safe day.
Nice Job..... son ! Go..... further !! All the best!!!
Thank you!!
great video and you explained it very supper and easy way to understand. I was hung on the Ventura way till I saw this. just what was I thinking. Thanks
Nice build, where did you get the fire brick? And with this being 1 burner what is the max length it will heat? Thank you
wow this is realy a nice work :D
Paul that is one beast of a burner and I have heard they're very hot and very efficient. Well done.
Thanks Len! It works even better than I thought it would I definitely recommend it if you use gas
Yeah I use gas and am thinking of it.
Приятно посмотреть на твоё творчество⭐️⭐️⭐️⭐️⭐️
mantap bang, sukses selalu ya..
I do the castable rectangular ribbon burners and love um
Totally amazed young man!
No drawings at all?? Master with your MIG as well!
Only thumb off hammer shaft when you forge! There is a C5 nerve ending in your neck and it will hurt in a while... Check Uri Hofi for ergonomi- and eyes and ears always!
Thank you!! yeah haha I don’t do many drawings for things even though I probably should. And thanks for the tip about holding a hammer I’ve never heard of that before but I have heard of Uri Hofi I really like his style and the types or hammers he uses with the stubby head and short handle
perfect
4:58
Nice beat, you oughta write a song...
How far does that flame go into that pipe does it go back to the burner or does the flame only exit at the hole plate.
If that blower stops for any reason (breaker switch) your going to get a backflash to the propane hose. No backdraft preventer. Or is there one on the propane regulator?
Trying to set up my own and the blacksmith down the street from me showed me his and says it heats up hotter and well of course quicker.
But now he's moving away🤷🤦
Could you make multiple size port outlets and be able to screw it on and off to change the hole size as well as clean it easily.
What would a bunch of 1/8th inch holes do?
I think I'm going to try to use a furnace blower and hook up a variable speed switch to it. See if the speed can optimize the fuel to air ratio
⚙️🔩🔧⚒️ Great job, great video 🎥 !! _ Congratulations! 👍 🇧🇷
I like the map on the wall
Paul this is great. Thanks for sharing. Do you think this would be hot enough for a small casting furnace? I'll use a low pressure regulator. Could turn up a few more psi. I appreciate your opinion. Thank you!
Dave
I am thinking of building a simmilar forge, how much fuel do you use in an hour?
non forge welding heat.
Thanks
Nice burner! I would strongly recommend earplugs when working with the grinder, cause tinnitus may not be a problem now, but it will be later in life and it's capable of driving you insane
Savage Porkchop - what’s that you say?? From 61 year old smith.
Huh?
The crickets are driving me batty.
Savage Porkchop yeah and maybe a guard on the angle grinder. gloves can be personal preference as some folks have been taught or perhaps have seen gloves get caught in motorized equipment and cause severe hand injuries. I personally kinda prefer them especially with an angle grinder so I have a good hold on that thing. oh, and a dust mask or respirator and eye protection
Thanks man...i forgot about my tinnitus till i read your comment...im going crazy now!!!
Great video, and thanks for taking the time to share it with us. Does this style of burner use less propane overall? What are some of the advantages to it?
nm, you covered it later in the video. Great video, I think I'm sold on this type of burner.
You can get Bessy clamps that have an adapter for gripping pipe that could help with the drill press.
I was wondering how hot does your 12" pipe nipple get just above your gas inlet. I've tried this style design but had some concern about burning inside of the tube, should you use flash arrestor and check valve on the feed ? I also incorporated a static air mixer in the 12" horizontal nipple to boost the efficiency, basically just a piece of twisted sheet metal..
Nice job will it get hot enough to forge weld
fire.start.after @5:40
Lookup static agitators. Theyre basically a light spiral you put in the pipe and it helps mix the fuel and air better before it reaches combustion
My butane gas blowtorch has an "impeller blade" baffle in the delivery tube about 1" back from the nozzle. Thanks for explaining why it's there.
Also wondering if the drilled plate at the end is good for casting or leave it off and get a cone shaped flame?
Hey Paul- how is this holding up? Any mods you would recommend if you were to do it over?
Nice build Paul, I need to changed my current forced air out for something like this. Few questions; how well is that 1/4" plate holding up at the end of the burner? Is the CFM of that blower enough? How far through your insulation does the burner extend? Have you tried to hit welding temps? Would you make any changes on this design??
Sorry for the barrage of questions! Lol
The 1/4 inch plate is holding up really good I think the constant flow of air keeps it cool. The blower is definitely strong enough I always keep it half closed. The burner is probably half way through the fire brick. And it will hit welding temps. I think how hot your forge gets depends a lot on the insulation if I were going to do a lot of forge welding I would use kaowool instead of just fire bricks. And I really can’t think of any issues with this design maybe if I were to do it again I would fabricate the whole thing out of tubing instead it just using pipe but it really works great
Paul Pinto sounds great, thanks for the reply! I'm just waiting for my blower to arrive in the mail then I'll be getting to it! Cheers!
Hey Paul,
Can I ask you what your blower CFM rating is?
Ive just finished a forced air forge with a 1.0mm gas orifice but doesnt seem to be getting as hot as what your forge seems to...
Cheers
Would also like to know how the burner is holding up after a little over 2 yrs now. need to decide between this or ribbon burner...
What prevents the flame from climbing up into the larger pipe full of mixed gas and air? If it did make it's way into the pipe would it potentially cause a dangerous explosion?
Has the burner plate melted on you at all? I made a square ribbon burner and used 1/4 inch plate for the burner surface and it completly melted in the forge
If you had a forced air burner without the ribbon burner effect with lots of holes, would it be any better and better on fuel compared to a Venturi burner?
Is there a way to install an adjustable orifice for the propane in case I want to tweak propane flow for efficiency purposes?
Thank you Paul, what is the dimensions of the forge and bricks?
Wow! This is so cool!! How is the forge holding up? Are you still using it?
any more specifics on the dayton blower? model #?
Hey Paul. What is the diameter of the main pipe and ball valve? BTW nice work :)
Hey, where can I find your belt grinder build video? I can’t find it on your channel, I try to reference every knife maker’s grinder to come out and built my own. Thanks
Paul, What is the model number for your Dayton Blower??
How far into the forge did the jet plate stick out? Or was it recessed up into the insulation a bit?
I dont know if you're still active on this vid but are you able to tell us how many days forging you would get out of a 20lb propane bottle?
Would appreciate it
Cheers
I'm not entirely sure.
Why do you ask?
I would definitely appreciate anything. Give into me.
Hey Paul, what psi are you usually running at for normal forging temps? I cranked up my regulator up (0 to 30 psi) and my forge definitely gets hot enough now but it seems like I'm really using a lot of gas to do it. I'm thinking that forced air would be much more efficient. Thoughts? thanks
Alright, well I should have watched all the way through before asking....you answered it! This seems like the way to go and I like how quiet your blower is vs. the cheap Coleman Blower Roy used in his video (Christ Centered Ironworks)
Haha sorry for the late response. Yeah I run the new burner at like 2 to 3 psi and the old one was sitting around 10 I definitely recommend building one of these no that you’re getting serious about blacksmithing. And yeah this blower is really nice. Very quiet and it has more than enough airflow.
ok, thanks my friend!
Vintage Wood Workshop yeah forced air with the right fuel mix is a bit more efficient with all the oxygen in the air that you force through there....
Definitely a different take on the ribbon burner. Is there a formula for how many 1/4" holes you drilled in comparison to the pipe diameter used?
Stoichiometry
I have to use methane provided by pipe with 1/4 psi pressure. Should I have to make any changes?
How much to build? I’m looking to make a forge. Do you sellthis assembly? I cannot weld so hard to do. I’d buy it
Is that blower from Amazon? If not can you share from where? Thanks.... Nice build
Yeah i got it on amazon it’s a Dayton blower
That rubber "thing" is a 2in coupling for connecting // splicing 2in PVC or other 2in
Plumbing pipe
How is it holding up? If your plate burns up r u going to have to cut the top of the forge off ?
This is free. That "rubber thingy" is called a transition in plumbing circles. You can buy them in wholesale plumbing stores, or your friendly neighborhood mom & pop hardware & plumbing stores.
George R Richter Jr I think that rubber thingy is called a Fernco
@@edwardsimpson6344 Fernco is a brand name.There are many brand names of couplers.
Nice job man. I just wanna know that how much gas will it consume in an hour?
How is the burner holding up
Thank you for your video, can you give us your fan model and recommended airflow?
I am making a foundry to make wootz with a double forced air torch.
Thank you for your help
Do you also have a materials list for the forge? Thanks
I've seen people cast ribbon burners instead, so they look like bricks instead of round cans. Is it necessary to do that or will this type do fine aswell?
The cast burners are cast in refractory cement and will withstand hotter temps for a lot longer time. A straight metal burner will eventually corrode and break down eventually.
Nice! Are you mig or flux welding
Step your drill bits up to your final size. It’s much better for your bits and equipment. Thanks for video!
Do you have a complete materials list?
So you got the blower on amazon____ There are multiple dayton blowers there. What is the model number?????????
Any issues with the drilled plate getting hot and melting?
Surprisingly no I just checked it the other day and it’s perfectly fine
how hot temperature it can reach?
this is free as well, it's a good idea to use oil when drilling into steel like you were. also perhaps clamping your material to the work surface for drilling so it doesn't jump up on the bit.
👍👍👍👍
I just built one and it doesn't work no where as good as yours. What size blower did you use?
Nice project and nice skill set. Wear eye protection next time.
Fernco. (That thingy)
What blower are you using
Have you thought about ways to adapt this idea to a natural gas system?
Can you give me the link that i can buy that blower?Or can you give me the model of the blower?thanks a lot
It’s a Dayton blower I got it on amazon
Can you tell me how many cfm is the blower you are using on your forced air burner?
It’s either 65 or 70 I forget exactly what it is but it’s one of the two
Paul Pinto thank you i am making one of your burners now, I have forced air burners but yours look better
