Sir, you are an inspiration! The detailing and quality of your furnace is an achievement to be very proud of. Your casting operations are the best I've seen outside of a commercial foundry. Regards Paul in New Zealand.
By far the best home workshop built furnace I have seen anywhere. I have been researching a furnace build for over two years whilst building my workshop. This is by far the way to go and I thank you very much for sharing this project with us. I am sure the outside of your furnace is cool when in use but would be nice to know. Now to check out the rest of your videos and I am seriously thinking of subscribing to your channel. Many thanks Bernie from the UK.
Furnace is 5 years old now and gets fired up about twice a week, still going strong. I can put my hands on the outside when the crucible is glowing it's very cool. Thinking about subscribing? there is no charge.
I really enjoy your builds, thanks for filming, reviewing, editing and publishing them. I have none of the tools you do, so I can only follow along wistfully plotting the future build of a tool shop I want to one day have.
Hi, very informative and this summer I'm planning to try at least melting aluminium and see where it leads me. I'll probably add it up to my machining videos already on line... Thanks for sharing, Pierre
Really nice project, the furnace really looks beautiful. As a side note, the audio , which I think was looping in the failed uploads, is oddly pleasant all on it's own. I was actually not certain that you hadn't done it deliberately for that very reason. Not until I began reading the comments anyway.
Gorgeous video. Well worth the wait. Thank you for fighting the good fight against TH-cam! After 2 years of procrastination, I'm finally ordering pieces to build my own backyard foundry, and I do believe I'm going to borrow a lot of ideas from this gorgeous build. I know you mentioned in the past that you didn't have any particular need to melt cast iron in this foundry, but is there any chance you might video a test-run with cast iron just to see how it goes? I know the higher temps puts stress on the refractory, so I understand if you're reluctant, but I confess I'm very curious.
With his choice of background music I was convinced he was constructing a device that would teleport flesh covered cyborg killing machines called Terminators through time to destroy humans
sorry to keep bugging you, but I have yet another question: I just tried out my riel burner, OMG heaven...I'm in heaven! Heats up the forge in 10 minutes, made my 1/4" wall crucible cherry red in 5, and was melting aluminum in 20, and SO much easier than charcoal and a blow dryer.... I found that once I got everything hot, I could turn it down to just barely on, and it kept everything cherry red....after this I might build a nice forge like yours! Ok, now for the question: is the opening in the lid necessary? I wouldn't ever think of putting a removable cap on it but I do lose a lot of heat through it so I was wondering if by capping it I could trap more heat. I was actually VERY surprised that my steel pail/sand and plaster forge didn't get that hot on the outside. It was too hot to touch with a bare hand but not OMG that's hot...I could barely even feel the heat through my gloves....
michael C The hole in the lid is essential. You need a lid to conserve the heat but without the hole ther can be no combustion.. It's like putting out a fire by covering it with a fire blanket.
First of all I want to comment your craftmanship and resourcefulness! I am about to start my own backyard foundry and I want to use the same used oil burning system. What was the maximum temperature of the foundry? Will I be able to smelt iron with it? :D
Awesome build thank you for the effort you put into your videos, so much to learn from them. Obviously you don't really need to given the quality of this furnace but have you considered making an electric furnace? from what I can work out they are quieter cleaner and cheaper to run these days.
No plans for an electric furnace. The waste oil one is virualy free to run. I have a small electric enameling oven which I have used to melt brass. The disadvantage is it takes a long time to reach melting temperature and if you wanted to do more than one melt you would have to wait again for the temperature to build up.
Thanks for the reply in the area I live in (Nr Redditch UK) there seems to be a shortage of waste oil a mechanic friend has a waste oil fired workshop heater and has trouble finding enough. Several companies collect and pay for it in the area it seems. I guess the time to heat up will be down to the size of the electric element.
My mechanic friend supplies me with all I want. Depending on the price of oil at the time he either gets it collected free or the collection company pay him. Also in the UK.
Excellent video and very instructive. I appreciate A LOT your "voice/comment less" filming style. Some guys are making some interesting subjects so boring because of their tone or useless chatting. Was just wondering the size of the crucible used at the beginning of the video and how long it takes to melt its aluminium content. Also how many man-hours went into the building of your furnace. How much do you sell them? Thanks so much in advance, cheers!
Glad you like the silent video. I get comments sometimes about not talking but most viewers like it. crucible is an A10, I don't sell furnaces and did not really take note of time involved as it was not important.
myfordboy Thanks for taking the time to answer. It seems your furnace could easily accomodate a much larger crucible. The lesser the space between the crucible and the furnace wall the more efficient isn't it (I might be wrong so I rely on your expertise)? Love your job, your videos and your channel! Keep it up! Thanks again
you are amazing good buddy. have watched several of yer videos. the little steam powered tractor was the coolest project I've ever seen. please keep makin vids, always a pleasure to watch. I was wondering if you've had any cracking in the refractory cement of this project? I'm planning on makin a my second furnace (the first cracked). also, what was the piece you poured at the end here?
Yes there are cracks but I thing this is unavoidable. It makes no difference to the performance. I did consider making the refractory in 2 or 3 separate"ring" so the cracks would only extend within each ring.
Use less water in your cement, mine call for 10% by weight. Sometimes adding more Grog (crushed fire brick or burned sand) helps. You simply fill the cracks with more cement, Most foundries reline their ladles & often the furnace every shift.
I recently got an oil pump and blower that was attached to a furnace. Do you think that would have enough output to do this? I can add a blower to increase the airflow rate
Hi myfordboy, compliment from me too. Just out of curiosity, is it possible to melt brass in your old furnace (I mean, the gas-furnace without oil firing). I'm building a simple gas burner, and I'm wondering if I'll be able to melt brass too.
elicottero I did try brass in my original home made furnace with the perlite/fire cement refractory and it melts it OK but I did not do it again for fear the refractory would suffer at the higher temperature. If the refractory is rated high enough there should be no problem.
Why did you install a number of two stopcocks to enter the gas oven, please thank the answer and how long it took for the gas to melt that iron you melted and used in the video
It's not gas it's fueled by oil. one for the air supply and one for the oil supply. I have a new design now th-cam.com/video/Vrk0lMhUcYA/w-d-xo.html I found the air tap not necessary. I am melting aluminium.
Seems like a few cracks appearing in the refractory, were they expected ? Is that a normal result with this type construction ? thanks, really enjoyed the videos, however wish you would NARRATE them !
Very Nice Video congratulations..!!. hey do yo have planes or info of your roller metal bender.? can you share it.? Thanks in advance fro your comments
Hello, very good oven! One question, how thick is the refractory material? And what is the diameter and height of the oven? How much temperature does the interior reach? Thank you !
Well, I'd like to. My email is juan-lopez92@hotmail.com . I am currently making a furnace to melt metals and I am seeing which thickness of refractory to use.
7 years later it is still used about even 2 weeks. Hundreds of melts have been made. There is a crack in the wall but it does not affect performance. I would consider making the walls in 3 sections if I did it again, doughnut sections.
How exactly did you make the torch to burn the oil. I always thought that oil had to be misted to burn but maybe that is just diesel. Im trying to get into this hole melting and casting and am trying to also use waste oil.
Hi, I was just wondering approximately how much used motor oil is required for one melt? I have accumulated about 5 gallons of the stuff, and was wondering how many melts I could get out of it. Thanks!
What kind of oil are you using? I've tried old engine oil and I'm having trouble getting it to stay alight. Just as an experiment I used some diesel fuel and yes that burnt fine. There the only two fuel sources I've used thus far. Without another air source I was able to start melting a 25mm x 25mm aluminium extruded box tubing. After burning for about 10 to 15 minutes the burner only managed to melt about 80mm from the end of the tube. I'm trying to find the video you did with your friend on the blower build but thought I'd comment here and hope someone has some helpful hints for me. Thanks.
I am using used motor oil. One of the criteria that decided whether to switch to oil was I wanted to be able to just use oil. Some guys pre heat with propane, kerosene, or build a wood fire inside but I did not want this. i can light straight away from cold just on the used oil. I pre heat the oil to about 35C. You need forced air for an oil burner. I have not made any videos with my friends, just me. Forget extrusions they do not make good castings.
Well, it works. I used up the last of my oil. I got some new used oil after posting an Ad online (gotta love the web) but no idea what the oil is. If I get some in my eyes my eyes sting like crazy and I need to step back. Think I’ll replace that. Before I add air I’m not getting the kiln filling up with flame. Once I turn on the air ( just a hair dryer at the moment) and seal with the top / lid the kiln is getting hot enough to melt. I just feel it could and should be better. I’m using 1/8 inch tubing for the oil feed but your using 1/4 aren’t you? I was wondering should I increase the size and maybe nozzle size.
On extruded aluminium. I don’t plan to machine it so is it suitable for things like knife handles, shelf fixtures. Basically, things that aren’t going to be machined?
@@markgiles8527 From the fuel tank to burner 1/8 is too small. Mine is about 3/8" bore you don't want to restrict the oil. I would still not use anything but previously cast metal if you want good results.
The music is some supplied with my video editing software. It is automaticaly trimmed so the music fits exactly with the length of the video and does not just stop at the end.
+last king A blower gives a large volume of air but at a low pressure. You need a compressor to produce the 15PSI to work the nozzle. If you want a set up that does not use a compressor there is a drip feed type of burner.
+last king Basically its a tube with a blower in the end and tube to drip oil into it. You need to be able to control the flow of oil with a needle valve. The furnace needs pre heating with this type of burner as the oil has to hit a hot surface to vapourise before it will ignite.
+last king You can pre heat with a propane burner or light a fire inside. All too messy for me. No need to preheat my furnace with the siphon nozzle burner.
An A10 crucible full of aluminium is melted in 30 min from cold and subsequent melts only take 10 minutes. I could reduce the warm up time by increasing the oil flow but the fuel is free so it's kinder to the refractory to warm up a little slower.
What are you using to build the furnace lining, it isn't Portland cement, right? that would exploded under those extreme temperatures. I'm trying to build something similar to this so can you tell me what you used to make it?
You can also buy 50lb bags of the raw material too, which is aluminum oxide and silicone dioxide and a few trace elements. Far cheaper than any ready made cement out there. You'll get something like 5 times what you would pay for ready made stuff and its easy enough to mix.

Смотрю давно, ничего и ни у кого лучше не видел, Великолепно ! Я Благодарен Вам !
Jestem pod wrażeniem :)
W Polsce jest takie pozytywne powiedzenie- "mechanizacja w domu i ogrodzie" widzę że manufaktura się rozrasta :D
That was a really interesting build. Very deserving of the name plate. That engine casting seemed complicated but it turned out beautifully!
Your furnace is most impressive, very professional .
I really enjoy your builds, thanks for filming, reviewing, editing and publishing them. I have none of the tools you do, so I can only follow along wistfully plotting the future build of a tool shop I want to one day have.
Thank you for the reload. The furnace is beautiful and your casting looks great.
That was one of the most beautiful diy castings i have ever seen. Well done, and nice furnace
Fantastic job David - Your furnace is very well designed and thought out Awesome video! 10 out of 10!
You are shit-hot at all this! Your the kind of of guy everyone wanted to have as their granddad! Great work as always!
Very cool i actually thoughg about running a pil burner furnace thats why came across your page thabks what great looking furbace so fuel efficient
That is a beautiful foundry furnace, great job. I would like to build one similar to it someday. Thank you for posting!
Congratulations !! A very nice furnace for your effort. I've really enjoyed this series.
I think we can all agree there is no such thing as a home made furnace that's better than this one
Nice work but way way more complicated & expensive than it needs to be.
Solid pour! Excellent pouring technique.
Beautiful job as always. I do love the final touch with that badge.
I've learned a lot from you, Sir. Thank you and please keep on...
Best video you have done this year in my opinion :)
Thanks for Re uploaded your video. Well done on your first try out & it came out perfect. Can't wait for the next part. 5 stars & 2 thumb up my friend

If u want to no sum thing u r the. Best one to look upon on u tube Q watt size crucibles do u recommend for home use
The one in the video is A10.
You need space around it for the flame to swirl around. Size depends on what you need to make.

clean as hell
Real beauty seing !! Thanks
Thank you!
with this new furnace you should be able to do iron casting.
Already done it!
Muy bueno! Gran resumen
belleza, me hizo recordar el taller de fundicion del colegio industrial de berisso
I've learned something from this, I always thought the stuff that oxidised on top of the molten metal was called slag.
Green Silver Slag and dross are used somewhat interchangeably to refer to the oxidized metals & impurities skimmed from the molten metal.
Well what ever it is you cetainly have it, nice video series thanks :)
good
the sounds crack me up.......mini steel mill......
Merci beaucoup pour cette vidéo;
thank you for this video.
You can use the money you save on propane to buy a bigger compressor. Maybe it is just bad timing but it always seems to be going in the background.
Rainbows871 A quieter compressor could be my next purchase. i am using what i already own.
First of all I want to comment your craftmanship and resourcefulness! I am about to start my own backyard foundry and I want to use the same used oil burning system. What was the maximum temperature of the foundry? Will I be able to smelt iron with it? :D

You need this much space around the crucible for an oil fired boiler like this to support combustion. A propane fired one could have a smaller gap.
myfordboy I see... thanks again for answering. I'm surprised how clean white your furnace remains in spite of burning used motor oil.
what about melting Tungsten... great job , i think you come from the metal industry
Dont be silly, Tungsten is almost never melted for anything. Its sintered.
So, you making a new motor? Excellent build series!
FlyMario The casting is the cylinder for my Aermotor engine. I have plans and castings for sale. myfordboy.blogspot.co.uk/p/aerm.html

you are amazing good buddy. have watched several of yer videos. the little steam powered tractor was the coolest project I've ever seen. please keep makin vids, always a pleasure to watch.

I'm planning on makin a my second furnace (the first cracked). also, what was the piece you poured at the end here?

You simply fill the cracks with more cement,
Most foundries reline their ladles & often the furnace every shift.
Superb, I wonder if it would work with used cooking oil.
Stephen Cook Yes it will.
I recently got an oil pump and blower that was attached to a furnace. Do you think that would have enough output to do this? I can add a blower to increase the airflow rate
+Rick Hermann The pump would work fine for kerosene but it would not be able to handle waste oil. The output should be fine though.
Hello , do you have more details on the burner , does it works only with a blower or also compressed air ? Great work !!
Full details here th-cam.com/video/Vrk0lMhUcYA/w-d-xo.html You need a blower and compressed air for this type of burner.
Wonderful craftsmanship! What temperatures can you reach on this lovely furnace of yours. Does it get hot enough to smelt iron/steal?
Can melt iron fine. Steel is not something that can be easily cast at home, need very controlled conditions.
Are you like a machine? Like part man, part machine? A man-chine?
Hi myfordboy, compliment from me too. Just out of curiosity, is it possible to melt brass in your old furnace (I mean, the gas-furnace without oil firing). I'm building a simple gas burner, and I'm wondering if I'll be able to melt brass too.

+Bonbadil Moi Yes it's a siphon nozzle. See here myfordboy.blogspot.co.uk/p/oil-burner.html
myfordboy thanks for the answer !
Do you think this will melt copper?

your using used motor oil in this application. do you think this would still work with used cooking oil (fryer oil) of course that has been cleaned.
XmackattackX Yes it will run on veg oil too.
Seems like a few cracks appearing in the refractory, were they expected ? Is that a normal result with this type construction ?
thanks, really enjoyed the videos, however wish you would NARRATE them !
***** Cracks are to be expected. If you want narration try tubal cain.
What type of flux did you add to the molten metal? Are you able to make flux or find flux from common household stuff?
This is a commercial drossing flux. Prior to using this I have used table salt or better LoSalt which also work well.
Very Nice Video congratulations..!!. hey do yo have planes or info of your roller metal bender.? can you share it.? Thanks in advance fro your comments
Hello, very good oven! One question, how thick is the refractory material? And what is the diameter and height of the oven? How much temperature does the interior reach? Thank you !
The furnace is capable of melting iron. I can send you a plan if you let me have your email.
Well, I'd like to. My email is juan-lopez92@hotmail.com . I am currently making a furnace to melt metals and I am seeing which thickness of refractory to use.
Has anything gone wrong since you did this? Is the refractory cement intact?
7 years later it is still used about even 2 weeks. Hundreds of melts have been made. There is a crack in the wall but it does not affect performance.
I would consider making the walls in 3 sections if I did it again, doughnut sections.
Great foundry! do you know what modifications you would need to do to cast steel? could you add regulated oxygen for example?
I have cast iron with this furnace. Steel is not a material that is usualy cast.
Yes it is. pretty tricky to do at home tho.

All too messy for me. No need to preheat my furnace with the siphon nozzle burner.
very beutiful! What is the flux and proportion?
neobionic1 The flux is EXF 326 from artisanfoundry.co.uk I use about half a teaspoon.
myfordboy Hey nice one! What's the approximative heat-up time of the furnace?
An A10 crucible full of aluminium is melted in 30 min from cold and subsequent melts only take 10 minutes.
I could reduce the warm up time by increasing the oil flow but the fuel is free so it's kinder to the refractory to warm up a little slower.
myfordboy Ok thanks because I just finished casting my furnace and the seller told me that I should heat up the refractory only of 100°C pee hour
I expect he means on the first fire up, to dry it out.
These is so helpful video but can i know the reason of flux being added does it protects the metal from getting oxidised??
The flux makes the metal more fluid and brings up impurities to the surface where they can be removed.
myfordboy what type of flux is used for zinc and aluminium to avoid getting oxidised ??
I don't use any flux for the zinc /Al I use.
myfordboy basically which furnace (Gas or Oil or Induction) is more suitable for melting ZN and Al without getting oxidised ?
If you had the choice I would go for induction. I have not had any issues with oil or gas though.
so i bought a a-20 super salamander crucible and I'm working on making my furnace any recommendation on how big the inside should be?
Nick Weaver I would allow 2 to 3" around the crucible for an oil burner and half that for propane.
wouldnt it be smart to turn the blower off at the same time as the fuel? so the heat doesnt just blow out as fast
+Anton Helsgaun No, If you turn off the blower you get smoke.
myfordboy what does the smoke come from? There's nothing combusable in it
What are you using to build the furnace lining, it isn't Portland cement, right? that would exploded under those extreme temperatures. I'm trying to build something similar to this so can you tell me what you used to make it?
You cannot use cement. You need a castable refractory. This is the product I used. artisanfoundry.co.uk/product_info.php?cPath=27&products_id=53
Thanks for the info, very much appreciated.
You can also buy 50lb bags of the raw material too, which is aluminum oxide and silicone dioxide and a few trace elements. Far cheaper than any ready made cement out there. You'll get something like 5 times what you would pay for ready made stuff and its easy enough to mix.
Do you have a video on the waste oil burner and do you sell them or would I just have to make it myself
+tankkiller308 I have a video here th-cam.com/video/wOj-2g9syhw/w-d-xo.html and here th-cam.com/video/gV6wcNA5wFk/w-d-xo.html also more info here myfordboy.blogspot.co.uk/p/oil-burner.html
