How to Build the Kwiky All Fuel Foundry Burner

This video shows how to make the Kwiky burner. Kwiky, because it is so easy to build. All fuel because it can be run on waste motor oil, waste vegetable oil, kerosene, diesel, propane, and natural gas too. It is the easiest way to build a siphon burner that works that I know of. It uses common plumbing and welding parts that you can get from any local "big box" store. You can see more details of how to build it on this web page: www.backyard-foundry.com/How-t...
If you build one, send me some hot pictures that I can post on my web site!! My e-mail is backyard-metal-casting-e-zine (@) backyard-foundry.com
Someone recently told me that you need to be careful when buying the plug fitting. they have one fitting that is not solid and doesn't have the bevel that I show in the video...You don't want that one!

[@mindofmadness5593]

Thanks. I have watched a ton of DIY vids on foundries but you are the first I've seen to explain the burner apparatus. Usually it's "I put my tip here and add air..." This gave me a clearer image of what is actually happening.

[@AnthonyMassey]

Had to give a big thank you!! You're a true DIY Guru. Free for the world. Easy to understand and follow. Awesome job!

[@ericrothleutner3080]

I have built this foundry burner haven't used it yet... But this is the easiest burner build I have ever done ... I am building a foundry 50% Plaster of Paris and 50% Sand... I am going to build a foundry that has a spring-loaded pour spout that comes out of the bottom of the foundry... this will make pouring ingots much faster than with a removable crucible... my ingots are going to be poured into muffin tins. THIS VIDEO HAS INSPIRED ME TO GET THIS FOUNDRY DONE BEEN WANTING TO BUILD THIS TYPE OF FOUNDRY FOR A WHILE NOW... THANK YOU FOR THE INSPIRATION TO GET BUSY...

[@backyardmetalcasting]

I am glad I inspired you! I do have some questions though and I am wondering if you researched fully the Spring loaded Furnace release and plaster of Paris for a foundry mix. I definitely would not use plaster of Paris if you are going to try a homemade mix I would use fire clay and sand. You would really be better off finding a refractory commercially made mix though. A homemade refractory won't last very long. A batch type furnace like a cupola uses a clay plug to block up the pouring opening while the furnace is being heated and the metal melted

[@KarlRoyale]

Great video! Shows and EXPLAINS the entire process as well as the functioning of the finished project. Very few videos are this concise and complete. Thank You

[@BadashGames]

I made one of these Kwiky burners today. It works just fine with the water test. Thanks for the easy to follow video and website!

[@backyardmetalcasting]

Yea! I'm glad it works for you!

[@johnkoury1116]

This is the most fantastic way to build a siphon valve ever. Thank you so much!!!

[@backyardmetalcasting]

You are welcome. Let me know how it goes!

[@johnkoury1116]

@@backyardmetalcasting I will. I just subscribed also. I am in Pa . Where are you my friend? Let me tell you what I am using this for. I have to melt some aluminum so that I can cast a bearing holder that bolts to the Swingarm? assembly on a 1985 Yamaha Trimoto. three wheeler. Thanks again.

[@backyardmetalcasting]

That sounds like a good project! I grew up neat Pittsburgh but I’m in North Carolina now. If you are on Facebook you should join the hobby metal casting group too. There are lots of knowledgeable people there.

[@theclintified]

I know this is an older video but I still want to thank you for sharing, got it built and will test tomorrow.

[@GregorKropotkin-qu2hp]

Very good, efficient design-and cheap to make! Well done and thanks for sharing your clever idea with us. Best Wishes-Gregor

[@builtrodewreckedit]

Put together one of your kwiky burners and was actually very surprised how nicely it worked. Its a nice easy to understand and duplicate design. I was at first hoping to stay away from using compressed air but now realize its not such a big deal after all. Thanks for sharing it with us

[@backyardmetalcasting]

builtrodewreckedit Glad you like it!

[@NicolasOrdahl]

Very nice build from available parts! Elegent in its simlicity

[@JBattler]

This is an amazing video....and thank you for showing the overall picture as you go. Thank you so much. I tried this a few years ago with veg oil but could never make it work very well. I'm sure this will do the trick. CHEERS!

[@backyardmetalcasting]

let us know how it goes

[@danvandertorre9280]

out of all the KZbin videos your atomizer is the best one .very good job .

[@backyardmetalcasting]

Thanks for that!!

[@TheMartywall]

Excellent Video, the best I've seen on the subject, thanks for posting.

[@backyardmetalcasting]

Thanks...I look forward to seeing the results you get too!!

[@allenhallman6483]

Awsome plans works perfect just burned my first furnace for the first time very impressed

[@DimaProk]

Ok, I seen this video before and coming back to it again. I like this simple build and need to just go out and build one! I have a friend who runs a business and has dozens of containers of oil, I can probably easily end up with 55 gal drum so need to do this burner and start melting aluminum and brass.

[@backyardmetalcasting]

Let me know how it goes!

[@elmayodejalisco]

Good project! thanks from Juárez, México!

[@neilsonlee7610]

Thank you so much..... I made this burner with a few modifications to fit my rig. I'll have it up on my channel here soon . Thank you very much!

[@Iloveorganicgardening]

let me know and i will post your video on my site

oops....that is my other profile! This is my metal casting one!

[@ColeHomestead]

great build david!

[@biggoldnugget]

AWESOME, I am building me one for the foundry I,m building...Thanks for posting

[@imysteryman]

A couple of years ago a friend of mine gave me a really big coffee maker about like yours for the oil tank, that thing will work perfect to heat the oil to thin it down especially in cooler weather. I almost scraped it out a couple of times so I just went to check to see if I still had it and it was there, thanks for sharing. unreal.

[@muskokamike127]

imystery man myfordboy heats his waste oil, he says it helps with ignition......

[@mksboysal]

Hey David, you made a totally awesome tutorial man. Thank you so very much. Tomorrow I'll be at the hardware store getting these parts. Thanks again man.

[@backyardmetalcasting]

Thanks, let us know how it goes. Someone told me that you have to be careful when you get the nipple part these days...evidently, they are making it hollowed out now. The one you want is solid from the threads to the end.

[@mksboysal]

David D, the parts cost around 40 bucks today in (Hawaii) this price also includes additional T to inject the propane alone, or separate inlet and two more needle valves. 1- to control the oil flow 2- to control the propane flow, (As a starting flame). I was testing the burner yesterday using Babington Burner type way, but flame was quite unstable. So, I am really glad you made this video Dave and remove the mystery out of this siphon valve. Later I'll make a video and share my burner with you guys.

[@frikkiesmit327]

Beautiful!!

[@andersb264]

Great video. Enough details to build my own siphon nozzle :-)

[@Retroweld]

Great job. Thanks, Douglas.

[@NOBOX7]

amazing build

[@TheMojaveMan]

thank you ill give that a try tomorrow i have an old metal pump sprayer ill use see if it helps at all along with oil preheat

[@valcye]

hahaha, love the thought processes, so simple, this is just what i need. good effort mate......... now how about cleaning up the yard.

[@EddieTheGrouch]

Dude! After a months of futzing with my wood burning / WO drip feed combo rocket heater I came across your video. While my Frankenheater worked okay with wood I would have to play with an air hose blowing into the opening, constantly adjusting the sweet spot, to get a hot burn. Then the wood disappeared fast. I tried a Babington burner and just made a mess. After watching this I ran out and bought the same stuff and made the vanilla model burner and now my 2 car uninsulated garage is 75F! I stole the coffee percolator oil warmer idea, too. Now to find more oil and build a forge for some mag wheels I have laying around. Thanks a bunch for sharing.

[@backyardmetalcasting]

Glad it worked for you!

[@chuckj5948]

I used your fuel supply design, with modifications/additions, to build a waste oil heater to heat a 24' x 52' work shop using a 55 gallon drum. This is a 12' high steel building with NO insulation. On last test I was able to raise the inside air temp. 18 degrees above the outside air temp. (40 outside 59 inside). I'm burning approx. 1 gallon per hour of oil so I should be able to calculate the BTUs based on the formula another commenter gave. Thanks for the design idea.

[@backyardmetalcasting]

glad it works for you...I would love to see a video or pictures?

[@magicman9486]

thanks for the simple explanation.

[@backyardmetalcasting]

Let us know if you make one and how it works!

[@nialpmatk04]

I used a 90 as my nozzle i stuck the tip in then adjusted till i got a super fine mist. Drilled the hole a hair bigger than the hole at the end of the mig tip

[@tucker934]

Hey David I wanted to tell you about the one I though together its basically the same thing just the mig tip is a 0.35 it does work how well I don't know yet I just tested it using water and a nebulizer for asthma the real test will be tomorrow I'll be sure to let you know how it does I have faith in it though I wish I can get you some pictures but I am not to sure how well its going to look I want to thank you quite a bit I love waste oil burners a lot kinda tired of the drip feeds though they like to go out of control on me but the big thanks is for taking your time to show us this with both videos especially thanks David best of luck Anthony

Glad to help!

[@iraqiman1854]

hello David, thanks for your precious idea, 2 months ago i watched this video, and i really like it, i decided to make some development on it, basically it works on the same way, but i made it more effective and it siphons liquid fuel by the pressure of the propane, soon i will share video.

[@backyardmetalcasting]

Ok please do!

[@memadmax69]

Just built one of these, works great, thanks man =D

[@backyardmetalcasting]

glad it worked well for you!!

[@dankortuem3924]

David I think your design is excellent. It burns great on #2 fuel oil. After it is hot I switched to 50/50 fuel oil/drain oil. Tomorrow I intend to heat the drain oil in a 30 cup coffee maker as shown in one of your movies. I built an oil burner based on your concept. It works well on my existing furnace. The bore of the furnace is 12” deep and 10” diameter. The pipe into the furnace is 1½”. Tomorrow I am going to fire and dry my new furnace. It is based on ½ of a 55 gal drum. The bore is 18” deep and the diameter is 15”. The pipe in is 2”. I intend to use the same 1½ burner. With a reducer to connect to the 2”pipe. If I am not getting enough BTUs in the big furnace I intend to make another burner unit. I will build it in a 2” pipe. I will bore the jet out to.O50 and the Plug out to 1/8. What do you think. I tried to e-mail you pictures but you e-mail address is not recognized Dan Kortuem

[@Iloveorganicgardening]

Send it to drescher3 (at) yahoo (dot) com. I need to update my website.

[@jakekeny5820]

fair play to you for taking the time to show the process im def going to make one one question how much waste oil per hour using this setup

[@andywells397]

Excellent

[@backyardmetalcasting]

I haven't checked that...I hooked up a pressurized tank now so I am sure I can crank it ip to whatever I want...the hago nozzles a lot of people use are 1 gallon per hour. Keep in touch with your results

[@capiberra4118]

Thanks, I'll give this a try.

[@backyardmetalcasting]

let me know how it goes!

[@YFUATIW]

Brilliant!

[@alwoolhouse6255]

I love this David, great job - super simple and straightforward. The only way it could be more simple is the drip oil approach. Anyone any inputs on the efficiencies of each? I have a couple of suggestions... (1) get a 1mm MIG tip and fill it with silver solder. That way you can drill an orifice to your exact requirements to set the BTU/kW output. (2) if your copper tube insert OD does not exactly match the ID of the T coupler then when you unscrew the end cap the tube will tend to move off-centre. Annular atomisers are super critical about the concentric location of the inner jet. Use some epoxy around the tube when you set the air tube inside the T coupler and this will keep it centralised. Make sure it gets far enough up inside the T coupler to hold it in position but not so far as to compromise the oil intake. You won't need to solder the back of the air tube in.

[@clydegray9714]

I'm going to give it ago. Your advice assures me success. My concern being dead center for siphon. Like silver solder tip as well. Thks. Gods speed

[@Stacyjtyler]

Awesome video. I would really like to see you do the same video. But with some temperature gauges and see which fuels actually heated up faster. Second I would like to say that no flame or suit I think means complete combustion so if you blew enough air in with the oil the flame would get a much smaller. So to ways to do this turn the oil feed down or turn the air supply up. You did have an awesome way of explaining things. I think you should also do some testing to see which ones get hotter faster.

[@backyardmetalcasting]

thanks!

[@MrThomasj95]

Very cool boss, not bad at all.

[@joohop]

put a water tank above that furnace and cycle the water through your house , hot water naturally rises and cold sinks back into the tank nice work bud keep it up

[@arnoldcustom]

make an oil pre heater out of a coil of copper tubing to pre heat the oil and you can fire the oil off right from the start and it will burn hotter and cleaner

[@frikkiesmit327]

This is so cool because you can burn with gas or oil

[@RocketcatLeeloo]

Great tutorial! Awesome design. I have some questions about the nozzle tip: After adjusting it the half-turn or so as you suggest, in order to get a proper mist, do you leave the tip easily accessible to adjust again later if needed? Or do you solder it in place in order to prevent it from loosening off, or tightening on it's own over time? Again, great vid!

[@backyardmetalcasting]

I haven't had trouble with it loosening up...so no I don't use anything to hold it in place...pipe dope could work because the tip won't get hot...it is important to take the burner tube out of the furnace as soon as you turn it off so it doesn't get too hot though. Thanks for commenting and let us know how it goes for you.

[@1AMERICANWORKER]

You have 1/4-28 threads on the mig tip. Run a tap in the tube. Buy the tap where you got the fittings.

[@crustyolcoot6646]

Michael Aumick I was thinking the same thing. Good on ya mate.

[@pitterpatter7719]

And 1/4 od on tubing. Tapping it 1/4-28 is likely to produce a cute lil copper coil at the end or maybe a good thread with maybe 2 thou wall thickness at the thread root and thus very weak. Plus, most likely, the rake angle on any tap you will be able to buy locally will not be appropriate for cutting copper and I would expect galling, a stuck tap, the tube to twist up like a corkscrew, etc...

[@JCLabs]

I may have to try this, I haven't casted in awhile because I've been having problems with my burner. Do you heat or filter your WMO?

[@backyardmetalcasting]

I use that big coffee pot to filter it. I tried to use it to heat the oil a couple times but it seemed to heat it too fast and made the oil bubble and smoke...and created burned carbon chunks. Maybe I could take it apart and disable the percolating part of it. It burns fine without preheat...and if the oil gets thicker in the winter, I can always thin it down with kerosene.

[@danvandertorre9280]

I don t know if you know this but your nozzle is the best of all youtube not one of the rest can do what your s can with your nozzle all you need to do is adjust it for deferent fuels making your nozzle the best one of them all well done david d .the ones doing a thumbs down are fools in my opinion.

[@backyardmetalcasting]

dan van der torre thanks for the kind comment. Most of the people who have a problem with it have modified it in some way.

[@localrider77]

So is there a air compressor plugged in the second fitting when running oil and then a fan blowing through the tube

[@joefrancis6854]

Great video! I'm having trouble locating the extended mig tip. Do you have a source you could share or perhaps a link? Thanks!

[@backyardmetalcasting]

There is a link for one in a comment someone left...I'll see if I can find it.

[@backyardmetalcasting]

Hello Yes the mixture is the hardest part. You can try thinning the oil with kerosene or diesel...heat up the oil to thin it...put the fuel supply up to create pressure...or some people have talked about putting a small aquarium air pump into a closed fuel supply to create a small amount of pressure. I am currently planning on making a fuel container from a propane canister ...my compressor had duel outputs so I can just put a fose out to the fuel container. It only should have to be 5 lb

[@nobackhands]

To save pre-heating with kerosene...add one cup of diesel to the used oil. It makes the used oil thinner. In fire demos this is what is used

[@Krant1980]

Hey David, thnx for the vid! Looking good! I have a question: did you tried to change the oil/air hoses? In other videos they had the oil from the center tip. I can't comparise these because this design is way better worked out.

[@backyardmetalcasting]

Vincent I tried it both ways and didn't notice a difference. Maybe someone smarter than me can do a test to see which way works better.

[@valcye]

I would think the oil/air mixture will depend on the viscosity. any thoughts on vapourising the oil will improve things no end, but it will have to be fully vapourised. No spits, lumps and dribbles.

[@jackofalltrades3700]

soo great my friend thanks for your info l will try it keep it up God bless you

[@backyardmetalcasting]

to continue...I tried a coffee peculator....the old type...to heat the oil...but it seemed to heat it up too fast.

[@Manxs1]

Do you think changing the mig tip to a 11-40 (.040) tip will cause any sort of major change? I have everything else the same as far as 1/8 inch fittings and nipple and i'm using 1/4 OD copper tube, just have a different mig tip as the 11-40 is what i had on hand. Just wanted to ask because before i solder the tip on, i'd like to know if it would be usable or if i should just got buy the .025. oh sorry btw, nice video.

[@mmart1nez]

Did you make the forge/oven? If so, what are the dimensions?

[@backyardmetalcasting]

Kawool would be nice...mine uses castable refractory. You can make it yourself or buy commercial stuff

[@333whateverdude]

I built a larger 55 gal drum furnace and I was thinking a propane torch would be enough on its own to melt aluminum but my furnace is to big to heat up with propane alone . Thank for this video I'm going to try your burner with propane and waste oil, that should heat it up

[@backyardmetalcasting]

+clay gundersen Let me know how it goes!

[@lawrence1md]

I wanted to ask if you tried the air supply in the front fitting? The air would go around the mig tip and pull the fuel through the mig tip orfice...

[@backyardmetalcasting]

Matthew Lawrence yes, It works both ways. I tried it that way first and then switched it and didn't see a difference. I guess I could pull out my vacuum guage and test which way pulls better

[@TheToolReview]

Dave where you getting your fittings at- at a cheaper rate ? I buy mine at lowes and they're much more expensive.especially the 1/8 fittings, I use 1/4 fittings because for some reason they are cheaper and I can run dirty waste oils with no need to worry about clogging. Keep up the good work

[@AFrayedKnotMate]

Depending on how many watts the blower fan draws you could either use a light dimmer or a variac to control the speed to control the air flow more accurately. Nice deisgn for the burner, I will probably make something similar depending on the parts available here.

[@moltenmayhem1]

What valve do you use for your fuel it doesnt look like any needle valves ive ever seen

[@jackofalltrades3700]

thanks my friend great work....can l ask you something? what about smell? it seen clean flame

[@backyardmetalcasting]

if the air mix isn't right it can smoke...if it is warmed up well, it shouldn't smoke at all...or smell

[@backyardmetalcasting]

Nice! Let me know how it works.

[@SVSeeker]

Good Stuff.

[@ifell3]

Great video, what CFM air compressor do you use?

[@backyardmetalcasting]

I'll have to check

[@pharcelle1]

[@boodogtom7599]

What did you use to insulate that bucket? I looked at buying some Kaowool. Kinda pricy.

[@jeffelsom2139]

the long mig tip is from an aluminum spool gun which is available at any welding supply store

[@dabearxx]

Hi all. I just built this and I wanted to add a few comments. At 5:42, you can see how the mig tip doesn't stay centered. When you solder the mig tip in, make sure you do so with it standing straight up. Otherwise, the mig tip will solder in crooked and it won't fit in. I also want to mention that if you are using mapp gas, it only takes about 6-8 seconds to heat it up enough for the solder. If you over heat it, the flux with fail. Propane probably takes a couple seconds longer. If you never soldered this way, look up a few videos. They help a lot. I was able to verify mine is working by attaching a 4 ft tube dangling straight down and the siphon pulled up water quickly and without hesitation. You may have to adjust the front tip to get the desired results. The pressured air has to go straight through the front hole for the siphon to be successful.

[@backyardmetalcasting]

Send me some pictures when you get it going and I will post them on the site!

[@tucker934]

Hey just to let you know man I am working on building one of these for a little heater that I am building I’ve built one of these before but that was definitely a long long time ago just wanting to make sure if it’s okay to add the link to the video on my channel when I start building it and everything I really do want to thank you for your time with this and passing it on thanks man really thanks

[@tucker934]

David D multi fuel heater it’s a contained system with no open flames just in the building and testing part right now but there is going to be safety things to keep from things happening but how I am going to test the burner I am going to Attempt to pump fuel to it in order to run low PSI for air

[@tucker934]

That old burner was not that great I was using a cutting torch tip of a acetylene torch BTW the way

[@65BAJA]

Just bought all the parts to make this burner. Wish me luck! lol.

[@backyardmetalcasting]

if you know how to do plumbing soldering, you should have no problems...it's very easy.

[@kevlauenterprises]

So haven't seen any comments about how much Kerosene this will burn per hr. running 30 lbs. of air pressure. I'd be curious on what the cost per use would be.

[@MON383]

Ever thought about (carefully) cutting spiral grooves into the outside of the mig tip with a hacksaw?

[@moltenmayhem1]

Question for you, how far from the end of the tube do you have the nozzle both when it's in the furnace and out in atmospheric. Also how far do you have the end of the tube from the bore of the furnace. Also I can't seem to find the tube size for your small tube it still seems to perform well even thou it's on the small side.

[@backyardmetalcasting]

Hello, My small burner tube is about 1 1/4 inch...It is really the first tube I found laying around just to try it out. My other burner is 3 inches and I still have to make a furnace to fit it!!. I haven't really played around with the burner tube. Of course it will burn a lot easier in the furnace and especially when the furnace is hot. My problem when I first used it was blowing too much air through it from the blower...It was actually cooling it off.

[@backyardmetalcasting]

That's right. I found the hardest thing is to get the air mixture right

[@Malzan1]

Hello. I build a similiar burner like yours but I can't get it started with waste motoroil. It is a bit different to yours because I can't get the same parts here in germany. But it sprays very good. Do you preheat the waste oil? Which temp?

[@backyardmetalcasting]

Are you burning it in a furnace? I would start it using diesel or kerosene. That will help you get the air set right. Then, whwn the furnace is hot, slowly switch to oil. Let us know how it goes

[@TheDaken]

I made one of your burners and its not holding the flame any tips?

[@NotSoCrazyNinja]

I see great potential for a thermal mass stove for heating a dwelling. Think giant pillar of cement with hollow center. Fire it on waste oil until the outside temp is reasonable. Then cut it off and let the heat radiate out. Of course the weight would be insane. Cost might be a little high as well lol. In theory however you may only have to fire it once a week for a day to keep a place reasonably warm.

[@a6emech]

I am interested in basing a boiler (for a small steam engine) on this burner. Have you ever seen that done before?

[@backyardmetalcasting]

No I haven't. You would have to be careful not to get the boiler too hot though would be my first thought.

[@lapisthewolfinblue5367]

if you force the tip in against the drilled plug how does the fuel get through? I had to back out my plug but seem to get fuel dripping out the back, having trouble getting full atomization any ideas?

[@backyardmetalcasting]

You have to put the tip tight against the plug to solder it in place...but then, you unscrew the plug a half turn or so to get the clearance needed.

[@memadmax69]

I was wondering, how long does a barbecuer sized tank of propane last you?

[@user-qo4tx6pc8r]

How could the copper tube and mig tip fit inside the pipe fitings if the copper tube is twice as big as the fitings?

[@backyardmetalcasting]

It couldn't. And it's not!

[@PDelta41]

What do you use for refractory? My refractories tend to crack and crumble.

[@bryannoyce]

He used store bought refractory rated 3000F. Have you tried packed fire clay? That is the cheapest and should withstand just as much heat.

[@backyardmetalcasting]

I've seen some nice furnaces where people use firebrick too

[@rafaelolarramorales2049]

Hola

[@tsunamiblast88]

Not shure if this was asked but do you an idea of the cfm your using through the tip? I would like to be able to run this off my on board air for my truck but its a little limited on cfm.

[@tsunamiblast88]

Answered my own question. I setup a test jig using what I had laying around, nozzle was much bigger then a .025 tip and my 2.5 CFM OBA maintained 50 psi at low battery voltage. So now to collect a regulator and some fittings. Thanks for putting this up. For anyone who is wondering I have the Masterflow 1050 compressor from pepboys, also sold as mv50 from other vendors. great compressor for the money on a trail rig.

[@backyardmetalcasting]

just saw your question....glad you got it answered...it does use quite a bit of air. The commercial nozzles will use less...they may be more prone to clog from what I understand.Let us know how it turns out for you!

[@donschoonover1068]

The long mig tip is a Profax PN/ 3123 sells for about $1.49 each BUT can only find them in a pack of 25 !!!!!!!

[@Mjeb01]

Great video by the way. I'm gonna put this together tonight. The only thing I'm not sure about is how you mounted it in the pipe?

[@backyardmetalcasting]

I drilled it so the tubes fit in tight and the fittings stop on the burner tube. Then I drilled and tapped for a screw to go onto the middle of the tube to hold it tight. See the web page in the link for a picture of it.

[@backyardmetalcasting]

kzbin.info/www/bejne/gIW3l6Nnjqp5isU This video shows one mounted in a larger tube

[@Mjeb01]

That's a monster! I will be interested in seeing the furnace you make for it. I ended up using a 1 1/4 pipe. I noticed you mounted the burner in the back of the tube on that one. I should be able to test mine tonight. I'll let you know how it goes.

[@jefffleming7061]

Jeff here again, I watched your video several times and I have done what you told us to do. I mounted the unit in the old wood stove and put a brake caliper in the bottom to help with mass and radiant heat. I get a mist of oil or kerosene out of it and I have tried several different air pressures, and adjusted the spray head. I can get the kero. to burn and heat everything up, but for the life of me I can not get used oil to burn. I took the unit apart to check my construction and tried it again. I have been all weekend on this project and can not get it to work. now what?

[@muskokamike127]

Jeff Fleming try heating your waste oil......or go over to myfordboy's youtube page and see how he does it....I forget what he heats his oil to but he says it helps with ignition......

[@TheMiKeOfAllTrades]

David, where on earth did you find that super long MIG tip? I have been searching online, and I can't seem to find one that long.

[@backyardmetalcasting]

I think I found it at a local welding shop and i think it is a Miller part but i just searched too and couldn't find it...I don't know if it is discontinued or what. I don't think i ever found one that had a small enough hole anyways.

Hi, I thought I could share this idea if you are not aware of it yet. 3D printer nozzle might give you some more flexibility, as they have standard hole from 0.2mm up to 1.2mm. It might be handy if you want to do a very small compact air. The only drawback are the metric thread which is M4 for these nozzle.

it's actually cheaper to buy M4 tap on ebay for about a buck than something less common like 1/4 x 20

It is a needle valve...not sure who makes it...but I can check when I have a chance. It was a valve that was in a box of brass fittings that someone gave me to melt!
