I have tried a lot of the DIY waste oil burner designs, but I have had mixed results. I built this one and did a test run yesterday--simply amazing. I did have to pre-heat my oil, but it was incredible how easy it was to light. I'm not good at soldering, so I had to build it with compression fittings. I used a male to male street elbow for the oil inlet on the top. I had to cut the threads down a little on the side going into the nozzle so everything would fit in the stainless pipe, but it does fit. I love that the design is modular. I can pull the whole stainless pipe out if I need to clean the nozzle on the burner or make any adjustments. Now I need to track down (or make) a variable speed blower like yours and I'll be set!
Thanks for the feedback, glad to hear it works for you. I have my fuel tank about 5ft high and find no pre heat oil is needed although if the air temp is below about 15C I warm it to make it flow better, this is for waste motor oil.
@@myfordboy Are you using a gauze strainer or paper filter for your used engine oil? I assume that gauze type mesh with holes smaller than 1mm would be fine, do you get any blockages or general build-up of any junk in the jet? Thank you!

Very nice job. The patience you must have makes me think that you might secretly be a doctor. Get it? Silly word play I know. Lol. The level of detail is awesome.
We have basically the same set up except I'm using 2.5" 304ss. And my air hose uses standard coupling so i just plug it in straight from the compressor. Don't know what size nozzle you have but i got the biggest one if i remember right. I tested it at 50psi and injected oil from a syringe.

Hi there. thx for the informative videos. your castings are top notch. i use a forced air burner. gas and air mix. im curious why you would not do the same. Seems cleaner and maybe faster. im surprised nobody has cried foul on the emissions...lol. (im not) the setup looks potent....nice. well made and engineered. Onward and upward my friend....
I have propane furnaces too, The first one home built, a keasnit one and a Vevor one. My waste oil supply dried up in Covid so I now use keroscene. It is hotter than gas.
I built a waste oil heater for a friends shop a long while back. I wrapped the coil around the heater to preheat the oil. It made the heater run so much better. I realize the furnace is insulated and doesn't have the capability.. just thought I would throw it out there. Nice work.
If you go back to my older videos you will see the set up. I pump the oil through an oil filter before filling my tank. The tank sits on a single ring electric burner so I can pre heat the oil if needed.
I've watched a few (too many) videos on oil burners and the best flame pattern yet i've seen is on a video by a guy called NOBOX7 ' - Godzilla build waste oil burner'. The tube is not the standard round profile but a square profile narrowing at the end. The flame looks fantastic and very very hot.
Hmmm...wonder what an airless paint sprayer would do if oil was used thru it? Then forced air thru the tube n all. Concept is to atomize the fuel and keep it lit being adjustable.
Does the tip of the jet finish at the absolute end of the stainless tube, or should the stainless tube be slightly longer? I am at the point of trimming the length of the tube down a bit, I was also wondering if the stainless does actually burn away with use slightly, and would it be wise for me keep it slightly longer than necessary so I can trim it as it erodes away? Thank you for a great video.

I've seen many waste oil burners thrown together hereon the Tube. However, I've until this day never seen one with a peened connector on the vane and 3 D printed parts..! Just awesome design and excellent craftsmanship. How does the stainless steel pipe do regarding the temperature in the furnace?
The stainless tube stops just short of the inner furnace wall and is no problem. Outside the furnace the tube is cool so no heat on the printed part. Design works well.
@@myfordboy Excellent..! I had something similar in mind for my burner, but I had second thoughts about using thin-walled stainless. Apparently, it works quite well. :)
So where's the link to that cute diffuser vane? Or is it something I need to have someone make on the cnc plasma? nevermind I just got to that part, the text @ the beginning had me looking for a link!
Hi, what was the pickling solution you were using? And does it work for brass brazing rod flux too? (Brass rod with white flux on outside, becomes hard as glass after brazing.. I need a way to remove it without damaging the base metal)
Hi Myford boy. You may have covered this before but have you tried different waste oils to comapre ? Obviously you have two major sources potetntially - motor oil from garages and vegetable based oils from chippys and take-aways. Have you used both to see what they burn like and temparatures they produce ? Thanks for the great video's !
I have only used waste motor oil. My supply has run out at the moment due to the lockdown and I have been using kerosene. The kerosene is easier to light but motor oil lights OK too. I believe the motor oil is hotter but have not real tests to prove.
@@myfordboy Thanks for your reply. Can you tell me what purpose the vane you made and inserted into the assembly was for ? I see that it was static and also before the atomizer. Was it there to make a sort of vortex air flow around the nozzle assembly ? thanks
The idea is to make the air spin as it leaves the burner. it's a feature of commercial burners. You need a means of centering the nozzle in the tube so this is how I did it. I also tried it with a simpler 3 prong arrangement, not sure if it was any worse . You can see my earlier version here myfordboy.blogspot.com/p/oil-burner.html
@@myfordboy Ok, I thought that might be the reason. Many thanks. I've ordered a couple of burners fron Bonggood. Now getting innundated with ads from them................:(. Have you thought of selling your oil burners - their does not seem to be many available for sale that I can find and I am sure crafters would be interested because of the fuel cost savings and the better tempratues that can be acheived from propane ? Not everyone has the equipment or desire to fabricate them themselves.
@@myfordboy My nozzle burns 3 US gallons per hour (500,000 BTU). The pressure regulator sprays # 2 fuel oil at 100 psi to the nozzle. One can turn that pressure up if need be. The 100 psi is the standard setting from Beckett. One selects the nozzle and flame retention plate from the Beckett catalog for a given btu yield value. Both the fuel pressure and the air intake damper are adjustable. On my last test firing I went from stone cold to 10# of melted aluminum in 30 minutes flat. I haven't tried bronze or cast iron yet.
myfordboy so if it only burns .75 an hr. Would a Becket burner from a oil furnace work to melt metal? Getting geared up to build a smelting foundry and always wondered if you could get enough heat out of a standard furnace burner setup? Thanks. Great build !!!
@@Mad.Man.Marine Not familiar with a Becker burner but the nozzle needs to be a shipon type if you want to use waste oil. The set up for a domestic heating boiler using a high pressure pump is no good for waste oil. OK for heating oil though.
myfordboy I figured as much. Waste oil being so thick and all. So if I used day off road diesel. Do you think it would have enough Btu’s to melt metal? Thanks Ian
Hi Myfordboy. Thanks for the .stl files, i've downloaded them and am asking a friend to print the parts off on his 3D printer. I have a question about the copper? part you attached the stainless steel fan too. When you fabricated the copper part you put on a small cylindrical stub on to one end perpendicular to the main peice and then tapped it out - but i could not work our what this small addition to the main body did, as you seemed to attach the fan on and then put it onto the assembly. I could not see what purpose that small part with the screw thread played at all. Thank you.
I presume these burners smell of the thing you are burning? e.g. veg oil or engine oil? Do you ever get any complaint from neighbours?? How long would 1 ltr of veg oil burn for (as an example)? Thanks.
Excellent, I have noticed how affordable these Chinese waste oil nozzles have become too, like you I acquired an expensive nozzle but can only melt iron in my furnace just like yours using the Artful Badgers waste oil nozzle which partly preburns some of the oil before it enters the furnace proper. Will you size your nozzle to melt iron? It should be interesting to see your furnace do that.
I can melt iron OK with the nozzle I have, This Chinese one is identical internally to the expensive Hago one. I can pre heat my oil as the oil tank sits on a single ring electric ring.
I've been putting together parts to build a furnace watching your vids. I came across the burner nozzle you are using in this vid and thought about buying one. I'm glad I see that you have confirmed their effectiveness. Your description says 1mm siphon nozzle but the link takes you to a 1.5mm link on Banggood website. What size nozzle are you using or do you recommend...1mm, 1.5mm, 2mm, etc...? Great vids btw.
Follow my link then on the Banggood site you have the choice of nozzle size. Where it says Length, click on one of the 5 boxes to choose the nozzle size. i am using 1mm.
You might even be able to melt steel with that(1600 Centigrade)! Last time I measured I hit 1100(will melt Cu) but no furnace! Was wondering where my Zeus book went! lol!
What kind of soldering torch is that, liquid fuel? I’ve only seen something like that in worlds fastest Indian... wonder if I can get one in the states.
Awesome videos mate. I have built a waste oil heater (just waste oil drip feed) but the fumes are quite smelly. It certainly upsets my neighbours. How does your burner go in this respect? I’m wondering if the better atomisation with the 15psi air supply might help in this respect...?
You should get nothing but that nice warm air smell if it's running right. You should have an excess of air so all the fuel is burned and having adequate turbulence and retained heat is also important.
Hello from Seattle WA! Another terrific video and one that I'm going to follow this weekend. Since I'll be moving from AL to Iron I'm assuming this is the burner you use with Waste Oil for your Iron castings, correct? Quick question... I'm surprised that the silver solder doesn't melt or eventually break down since its at the very business end of the burner. Obviously it doesn't get hot enough at that location, but just out of curiosity how is that possible? Thanks so much for all you do! your experience and guidance is so very appreciated! Best, Bob
No problem using silver solder inside the burner. It would have to reach near to the meting point of the brass nozzle to melt. Inside the burner tube it is cooled by the blower air too.This burner will melt iron.
@@myfordboy Ok ! thank you very Much !.....Design a reciprocating Hacksaw for the Myford ! I got mine just about ready to build...( metal saw that uses the lathe for power) I'm interested in what you would come up with ! .....later ! Bob....
I have done the same burner, 1.0 chinese nozzle. Outside furnace I can burn only kerosene or diesel, but waste oil or veg oil do not burn. (I can burn the only if pre heat more than 120°C . Where I do wrong?
I have not tried to burn waste oil with the burner not in the furnace. I have my waste oil tank mounted about 5ft above the burner to give some pressure to the oil in cold weather I heat the oil to about 40C. With kerocene the fuel tank can be at floor level and the nozzle will syphon the fuel but it does not work for waste oil.
Ta! for quick answer. I haven't tried to elevate the oil tank because I see that the oil is sucked well from nozzle. Today I'll try. I will also try to put the burner intote furnace. I'll let yo know.
@@myfordboy I solved. Thank you for right support. I mount the oil tank 1mt above the burner, change the tube form ID 6mm to ID 8mm (to achive more flux) and warm the oil to 35-40°C and I put the burner into the furnace and itworks perfectly on the first try. I see that it needs only a very little air flow from blower to have a good flame. Is it correct?
The amount of air needed would probably depend on the furnace design. Just adjust the air flow to achive a good flame. ^mm pipe was a bit small mine is bigger, maybe 10mm, sorry I forgot to mention that. A lot of waste oil burner uses have to start with propane or keroscene and switch to oil when the furnace is hot. I have never found this necessary.
@@myfordboy Are the internal burner's pipe also 10 mm? For internal burner's pipes I use ID 6mm for air, ID 8mm for oil (up to needle valve) and 10mm rubber tube from needle valve and oil tank. My furnace is the exact copy of yours, and works like a charm ! :)
@@myfordboy Thanks, I'll test like that, mine was about 50 to 60mm behind the end of the tube and I wasn't getting flame sustentation and when I do, there was too much smoke and unburned oil dripping.
I've ordered a couple of the oil nozzles through Banggood - 2 - 3 weeks delivery. I assume most of the gear is made in China, but wondered how have you found the quality of the engineering stuff they sell please ?
Hi Myfordboy, Any chance of an eBay link to the exhaust repair tube, I've tried all sorts of combinations of terms for a search and can find no 2" tube, and only metre lengths. Thanks for the vid.

Excellent video and design! I'm going to order one of those nozzles too. Is the stl file going to be on your thingiverse page? What psi are you running from your compressor?
I have uploaded the STL file here www.thingiverse.com/thing:4030376 You can vary the size of flame by changing the pressure between 10 and 15psi or more if want to.
@@builderofstuffBlower and air are turned on first then the fuel. Video here of my original burner showing start up. I don't do the 20 minute warm up any more, just light with the crucible in place and metal would be melted by 20 minutes from cold. ua-cam.com/video/HJ9YoRMoO5Y/v-deo.html
Life happened unfortunately. I have been trying to get back into it but haven't had the motivation or felt very humourous for some time now. Have been planning some Vids but with half the country on fire ATM, including places very close to me, doing burning Vids would not be the best idea. Maybe something around March when things calm down or we get some decent rain.
youd need to make another burner for propane, the nozzle is for liquid fuel, propane might work but it could also burn too quickly and overheat the nozzle. You should take those things into consideration.
Look up combination burners like those used in a Scotch Marine boiler. They typically have two methods ( gaseous or liquid fuel oil burners in the same tube.) In those cases, one fuel is generally the primary and the other the secondary. They are not run at the same time. Orifices for the fuel and oil need to be matched with the correct amount of combustion air. Gets tricky without dampers or speed drives.
I have tried a lot of the DIY waste oil burner designs, but I have had mixed results. I built this one and did a test run yesterday--simply amazing. I did have to pre-heat my oil, but it was incredible how easy it was to light. I'm not good at soldering, so I had to build it with compression fittings.

@@myfordboy Excellent..! I had something similar in mind for my burner, but I had second thoughts about using thin-walled stainless. Apparently, it works quite well. :)
So where's the link to that cute diffuser vane? Or is it something I need to have someone make on the cnc plasma? nevermind I just got to that part, the text @ the beginning had me looking for a link!
What is the purpose of the "fan" blade at the end? Is it to create air vortex? What for?
The idea is it will spin the airflow and give improved flame pattern. Not sure how effective it is.
Excellent job Sir. Thank you.
Hi, what was the pickling solution you were using? And does it work for brass brazing rod flux too? (Brass rod with white flux on outside, becomes hard as glass after brazing.. I need a way to remove it without damaging the base metal)
It's dilute sulphuric acid ( battery acid + more water) Works on all metals after using Easyflow flux.
@@myfordboy it must be disposed of at a chemical recycling center. If it gets in the river the copper will kill every fish for miles :(
Hi Myford boy. You may have covered this before but have you tried different waste oils to comapre ? Obviously you have two major sources potetntially - motor oil from garages and vegetable based oils from chippys and take-aways. Have you used both to see what they burn like and temparatures they produce ? Thanks for the great video's !
I have only used waste motor oil. My supply has run out at the moment due to the lockdown and I have been using kerosene. The kerosene is easier to light but motor oil lights OK too. I believe the motor oil is hotter but have not real tests to prove.
@@myfordboy Thanks for your reply. Can you tell me what purpose the vane you made and inserted into the assembly was for ? I see that it was static and also before the atomizer. Was it there to make a sort of vortex air flow around the nozzle assembly ? thanks
The idea is to make the air spin as it leaves the burner. it's a feature of commercial burners. You need a means of centering the nozzle in the tube so this is how I did it. I also tried it with a simpler 3 prong arrangement, not sure if it was any worse . You can see my earlier version here myfordboy.blogspot.com/p/oil-burner.html
@@myfordboy Ok, I thought that might be the reason. Many thanks. I've ordered a couple of burners fron Bonggood. Now getting innundated with ads from them................:(. Have you thought of selling your oil burners - their does not seem to be many available for sale that I can find and I am sure crafters would be interested because of the fuel cost savings and the better tempratues that can be acheived from propane ? Not everyone has the equipment or desire to fabricate them themselves.
I have no plans to make any burners for sale.
What hammer is that at 12:26 ? The tiny one ? Id like to find me one
It's a small ball pein hammer, I've had it for years.
By typists correction fluid, do you mean 'white out?' Also nice design. Thumbs up.
Tipex or white out.
Can you provide a rough guess on waste oil consumption? Like a gallon per hour or something similar etc?
Great video!
This size nozzle is rated at 0.75 gallon/ hour, I would guess that's about right.
@@myfordboy My nozzle burns 3 US gallons per hour (500,000 BTU). The pressure regulator sprays # 2 fuel oil at 100 psi to the nozzle. One can turn that pressure up if need be. The 100 psi is the standard setting from Beckett. One selects the nozzle and flame retention plate from the Beckett catalog for a given btu yield value. Both the fuel pressure and the air intake damper are adjustable. On my last test firing I went from stone cold to 10# of melted aluminum in 30 minutes flat. I haven't tried bronze or cast iron yet.
myfordboy so if it only burns .75 an hr. Would a Becket burner from a oil furnace work to melt metal? Getting geared up to build a smelting foundry and always wondered if you could get enough heat out of a standard furnace burner setup? Thanks. Great build !!!
@@Mad.Man.Marine Not familiar with a Becker burner but the nozzle needs to be a shipon type if you want to use waste oil. The set up for a domestic heating boiler using a high pressure pump is no good for waste oil.
OK for heating oil though.
myfordboy I figured as much. Waste oil being so thick and all. So if I used day off road diesel. Do you think it would have enough Btu’s to melt metal? Thanks Ian
Love your videos. What was your pickling solution?
Mine is dilute sulphuric acid. citric acid is a safer option.
@@myfordboy Thanks. Just used hot water in my bicycle framebuilding days but that looked much easier.
Excelente trabajo
Is there oxygen gas in the air section next to the waste oil?
The burner has a blower to proved air for combustion and a compressed air supply to spray the oil. No oxygen.
I forgot - Doh! Please accept my seasons greetings for a happy and prosperous New Year
Hi Myfordboy. Thanks for the .stl files, i've downloaded them and am asking a friend to print the parts off on his 3D printer.
I have a question about the copper? part you attached the stainless steel fan too. When you fabricated the copper part you
put on a small cylindrical stub on to one end perpendicular to the main peice and then tapped it out - but i could not work
our what this small addition to the main body did, as you seemed to attach the fan on and then put it onto the assembly.
I could not see what purpose that small part with the screw thread played at all. Thank you.
The part is brass. The boss with the tapped hole has a set screw and is used to attach the assembly to the burner.
@@myfordboy Ah hah. Thanks.
I presume these burners smell of the thing you are burning? e.g. veg oil or engine oil? Do you ever get any complaint from neighbours?? How long would 1 ltr of veg oil burn for (as an example)? Thanks.
I have only used wate motor oil. There is no smell or smoke it burns cleanly.
so whats the point of the blower if you are using compressed air?
Comressed air creates the fuel mist and low pressure high volume air from the blower supports combustion.
Excellent, I have noticed how affordable these Chinese waste oil nozzles have become too, like you I acquired an expensive nozzle but can only melt iron in my furnace just like yours using the Artful Badgers waste oil nozzle which partly preburns some of the oil before it enters the furnace proper.
Will you size your nozzle to melt iron?
It should be interesting to see your furnace do that.
I can melt iron OK with the nozzle I have, This Chinese one is identical internally to the expensive Hago one. I can pre heat my oil as the oil tank sits on a single ring electric ring.
I've been putting together parts to build a furnace watching your vids. I came across the burner nozzle you are using in this vid and thought about buying one. I'm glad I see that you have confirmed their effectiveness. Your description says 1mm siphon nozzle but the link takes you to a 1.5mm link on Banggood website. What size nozzle are you using or do you recommend...1mm, 1.5mm, 2mm, etc...? Great vids btw.
Follow my link then on the Banggood site you have the choice of nozzle size. Where it says Length, click on one of the 5 boxes to choose the nozzle size. i am using 1mm.
You might even be able to melt steel with that(1600 Centigrade)! Last time I measured I hit 1100(will melt Cu) but no furnace! Was wondering where my Zeus book went! lol!
What kind of soldering torch is that, liquid fuel? I’ve only seen something like that in worlds fastest Indian... wonder if I can get one in the states.
It's a camping Gaz butane torch.
Awesome videos mate. I have built a waste oil heater (just waste oil drip feed) but the fumes are quite smelly. It certainly upsets my neighbours. How does your burner go in this respect? I’m wondering if the better atomisation with the 15psi air supply might help in this respect...?
With the air set correctly there is no smoke and no fumes that I am aware of. I was surprised how clean it burns.
You should get nothing but that nice warm air smell if it's running right. You should have an excess of air so all the fuel is burned and having adequate turbulence and retained heat is also important.
Hi, but used oil is pure or is diluted with diesel or petrol
It will run on waste oil no need to dilute or preheat the furnace.
Wow, awesome job👍
Just curious, what is the advantage of your device over the many that oilburner made.??
From memory most of Oilburners burners just melted metal outside a furnace. Mine is a neater solution i think.
Why do you not use ferrule connectors that can be crimped on to the pipes. And avoid soldering ?
Know for a fact that such connections work well.
Not enough room inside the pipe to used compression fittings.
@@myfordboy Thank you dear Sir. Am a big fan of ur work.
Hello from Seattle WA! Another terrific video and one that I'm going to follow this weekend. Since I'll be moving from AL to Iron I'm assuming this is the burner you use with Waste Oil for your Iron castings, correct? Quick question... I'm surprised that the silver solder doesn't melt or eventually break down since its at the very business end of the burner. Obviously it doesn't get hot enough at that location, but just out of curiosity how is that possible?
Thanks so much for all you do! your experience and guidance is so very appreciated!
Best,
Bob
No problem using silver solder inside the burner. It would have to reach near to the meting point of the brass nozzle to melt. Inside the burner tube it is cooled by the blower air too.This burner will melt iron.
Why not get a junk oil pump from an engine and connect it to an electric motor you can speed control, plus you can have an oil filter in line with it
You wont be able to get a mist spray with that set up.
@@myfordboy assuming it is connected to a nozzle it will, similar to how it's used to spray the underside of pistons for cooling
Any chance you could put up a link to the torch your soldering with ? that is alot hotter than my propane torch !!!....Bob.....
Torch is a camping Gaz one, uses butane. Old model.
@@myfordboy Ok ! thank you very Much !.....Design a reciprocating Hacksaw for the Myford ! I got mine just about ready to build...( metal saw that uses the lathe for power) I'm interested in what you would come up with ! .....later ! Bob....

Hi, what gauge is teh exhaust repair tube? Do You think that a stainless rolling pin tube stand the hea (I happen to have one)?
Excuse the typo - teh instead of the - it's a praticular fault I find hard to remedy

@@myfordboy
Cheers.
Where do you usually get the waste oil?
I have a friend with a motor repair business.
I have done the same burner, 1.0 chinese nozzle. Outside furnace I can burn only kerosene or diesel, but waste oil or veg oil do not burn. (I can burn the only if pre heat more than 120°C . Where I do wrong?
I have not tried to burn waste oil with the burner not in the furnace.
I have my waste oil tank mounted about 5ft above the burner to give some pressure to the oil in cold weather I heat the oil to about 40C. With kerocene the fuel tank can be at floor level and the nozzle will syphon the fuel but it does not work for waste oil.
Ta! for quick answer. I haven't tried to elevate the oil tank because I see that the oil is sucked well from nozzle. Today I'll try.
I will also try to put the burner intote furnace. I'll let yo know.
@@myfordboy I solved. Thank you for right support. I mount the oil tank 1mt above the burner, change the tube form ID 6mm to ID 8mm (to achive more flux) and warm the oil to 35-40°C and I put the burner into the furnace and itworks perfectly on the first try. I see that it needs only a very little air flow from blower to have a good flame. Is it correct?
The amount of air needed would probably depend on the furnace design. Just adjust the air flow to achive a good flame.
^mm pipe was a bit small mine is bigger, maybe 10mm, sorry I forgot to mention that.
A lot of waste oil burner uses have to start with propane or keroscene and switch to oil when the furnace is hot. I have never found this necessary.
@@myfordboy Are the internal burner's pipe also 10 mm? For internal burner's pipes I use ID 6mm for air, ID 8mm for oil (up to needle valve) and 10mm rubber tube from needle valve and oil tank. My furnace is the exact copy of yours, and works like a charm ! :)
Where did you purchase the fan blade?
I made it as shown in the video.
whats the distance between the tip of de nozzle and the end of the tube?
I've got mine about 5mm. It's easy to adjust if you wish.
@@myfordboy Thanks, I'll test like that, mine was about 50 to 60mm behind the end of the tube and I wasn't getting flame sustentation and when I do, there was too much smoke and unburned oil dripping.
What about check valves? No need of one?
No and in a later update I have done away with the air valve and replaced the needle valve with a ball valve.
@@myfordboy cool I'll have to look at that thanks.
Which nozzle size of Chinese siphon do you use? 1mm?
1mm
I've ordered a couple of the oil nozzles through Banggood - 2 - 3 weeks delivery. I assume most of the gear is made in China, but wondered how have
you found the quality of the engineering stuff they sell please ?
All the engineering products I have had have been excellent quality.
Hi Myfordboy,
Any chance of an eBay link to the exhaust repair tube, I've tried all sorts of combinations of terms for a search and can find no 2" tube, and only metre lengths. Thanks for the vid.
Search for exhaust repair tubing, lots to choose from here is one www.ebay.co.uk/itm/EXHAUST-TUBING-PIPE-T304-STAINLESS-STEEL-All-Sizes-HIGH-QUALITY-REPAIR-SECTIONS/223157033981?hash=item33f5321bfd:m:mxHO5xLh_C9x-3ccZJqgkOg

if u ever read my comment how about building the david gingery machines?
I have the machine he describes so no need to build one.
Can you melt bronze 2200 degrees fahrenheit?
No problem. Can also melt iron.
@@myfordboy How long do you think it would take to melt 30 lbs of bronze?
@@TheAdirondack70 you would need a larger crucible to melt that much in one go
@@myfordboy building a beer keg foundry.
How do you filter your oil ? I don't care much for that design be OK for a clean kerosene or diesel fuel but not a waste oil ,sorry
You are the expert.
What's a "typist", and where can I get one?
You need a time machine and travel back to the 70s.
Congratulations
Lovely!!!
Your copper tube is that 6 mm internal diameter?
6mm OD.
how long should the 2" stainless tube be?
Mine is 250mm but it's not critical.
Do you sell your stuff? I would buy this.
I don't have any for sale, just made it for myself.
For me just genius
Stellar!
Excellent video and design! I'm going to order one of those nozzles too. Is the stl file going to be on your thingiverse page? What psi are you running from your compressor?
I just ordered my nozzle, can't wait for it to get here. I've always wanted to try casting with waste oil.
I have uploaded the STL file here www.thingiverse.com/thing:4030376
You can vary the size of flame by changing the pressure between 10 and 15psi or more if want to.
@@myfordboy Do you have the leaf blower running when you first light it? Or do you light it and then turn on the leaf blower?
@@builderofstuffBlower and air are turned on first then the fuel. Video here of my original burner showing start up.
I don't do the 20 minute warm up any more, just light with the crucible in place and metal would be melted by 20 minutes from cold. ua-cam.com/video/HJ9YoRMoO5Y/v-deo.html
Hi Myfordboy, do u mind to share the manifold 3D file? Thx for your great job!
Sure. let me have an email to send it to or contact me at the address you will find at myfordboy.blogspot.com. Is it the STL file you want?
That reminds me, I wonder what on earth happened to that crazy Australian, Oil Burner, been a good while since he posted anything.
I know he was banned from posting on Alloy Avenue forum.
Probably in jail!
@@MrCoffeypaul Not quite but thanks for the kind thoughts.
@@myfordboy Yeah, so were a lot of other people that didn't toe the candy arsed one way of thinking those hypocrites went on with.
Life happened unfortunately. I have been trying to get back into it but haven't had the motivation or felt very humourous for some time now. Have been planning some Vids but with half the country on fire ATM, including places very close to me, doing burning Vids would not be the best idea. Maybe something around March when things calm down or we get some decent rain.
now you can melt cast iron
Slick
It is possible to use waste oil and propane together ?
youd need to make another burner for propane, the nozzle is for liquid fuel, propane might work but it could also burn too quickly and overheat the nozzle. You should take those things into consideration.
@@laharl2k thank you very much .
Look up combination burners like those used in a Scotch Marine boiler. They typically have two methods ( gaseous or liquid fuel oil burners in the same tube.) In those cases, one fuel is generally the primary and the other the secondary. They are not run at the same time. Orifices for the fuel and oil need to be matched with the correct amount of combustion air. Gets tricky without dampers or speed drives.
@@chrisg1846 thank's for your valuable advices,I don't have much experience on combustion systems,so all the good ideas are always welcome.👏👍
