extremely clean build. your vids always inspire me i appreciate the silent filmography there is nothing worse than someone going on about an unimportant fact when youre looking for solutions. your experience shows thanks from Canada for posting your vids and keep em coming
+mikey worth except the shitty camera mount and its clicking noise!
,:
Really, I like all your ideas. They simplify my understanding of the way a burner works.
That correction fluid trick is something I've never heard of and really useful!
Great tip about using Tippex correction fluid to stop solder getting on the threads. I've used acetylene soot before, but never heard of using Tippex. Brilliant. Must remember to commit that one to memory! Thanks.
GREAT SKILL, I just sat watching your skills and movements! Greetings from Bulgaria!
I wish you would’ve been my teacher in high school for all three years I took of auto shop as an elective. I learned a lot then and had good teachers, but your methods of teaching and projects you do are awesome.
I learn a lot from you !! All your videos are great work. long life , health and peace. Thank You!!
How did I miss this..I absolutely love being able to make everything that we need to make everything we need to make.....you know what I mean...Merry Christmas my friend...
Another great video, thanks Dave. I have found all I need except the gas tap, I'm sure I will have one in one of my sheds lol
Just love these videos. Even relatively simple jobs are meticulously done with the greatest care and attention to detail. It's almost hypnotic to watch.
Nice! Thank you for ALL of your videos. They are VERY informative.
Wow, nice job on your burner'' one of the best how to videos I have watched!
ALWAYS GREAT! thanks for the vids
I had no idea about typist correction fluid being useful to protect threading. Thanks for the exellent tip!
Excellent filming and very clear instructions and very helpful written notes and a nice and clean design.
Like i said before I've been casting now only for a few months an i get frustrated alot when my molds fail ECT. I love doing this. But watching ur videos helps out so much.Thank u
Great craftsmanship mate! Thank you for sharing
nicely explained with clear language and matching teaching aids. Kudos
great tutorial bro, the spirit of work, don't forget to stop by for coffee to add to the spirit of being creative...
Just finished making mine excellent performance
A pleasure to watch. Goes to show he's a real professional at this. If you go to his blog you'll find he's into Stirling engines as well which is very interesting.
However, after watching all these videos on gas furnaces I'm tempted to go with a coal furnace because (a) coal is cheaper and (b) coal is safer and (c) coal requires no special conditions for storage.
I basically just need to melt down a large quantity of scrap (junk) Gold and Silver I've purchased over the last 40 years into bars I can easily sell that are (a) not too large so as to be prohibitively expensive for buyers; nor (b) too small as to be prohibitively expensive to have the bars assayed and certified individually.
Sure, there are places that will do the melt for me but here in eastern Europe it's on a leave-it-here-and-we'll-smelt-it-for-you-when-we-get-around-to-it basis where you leave them 50kg of metal, then pay them to melt all 40 kilos of it so you can come back 2 weeks later to collect all 30 kilos of it in bars.
In short, I'd rather do it myself, especially given the fact that I apprenticed in metallurgy as a child before going into banking, and YES, there really IS a common thread.
I did try mailing a test batch to a USA refiner for smelting and assaying but the result was not to my liking because I know exactly what I have and I assay it myself, but with the larger quantities I'm dealing with I'd rather have it assayed by a western state assaying office, like the one in Vienna which I am familiar with..
Also looked into electrical smelting but that seems too time consuming since the smelter typically only handles 3kg of Gold (or cca 2kg of Silver) per melt and I'm not going to be sitting here for months at a time melting down Silver into little bars. Getting a bigger furnace is also not really an option because at that point I'd actually be getting into the business of smelting metals which defeats the purpose.
BUT, problem with a coal smelter is that this must be done outside, hence no privacy!
I really don't know what to do, because any method I look at has 100 problems with it. Yes, I can actually rent a smelter all to myself, but that's in northwestern Czech Republic and getting the material there and back is a bit too "interesting."
First class video, very clear. Many thanks.
You have great tool sir, may be some day you can explain it, make detail tour of it. Thanks for great work and inspiration to create! Cheers!
Skur_Do Not sure which tool you are referring to but I have a video of my lathe The Myford ML10 Lathe and one of my mill
The Raglan Vertical Milling Machine
You do a wonderful job. Because this is so dangerous to do at home, I will go next door.
How can anyone dislike this video? The sheer ingenuity should guarantee a like! For gods sake, what a miserable bunch you few are!
Damn it, I can't make one of these 'cos we only have Diet Cola cans in our house! :-)
Again, another nice clear instructional video.
perfetto...sei un maestro parexellence....grazie mille per questo magnifico video...
From INDIA.
Very good presentation.
Thanks.
Thank you from Venezuela. congratulations.
Atm john velasquez
That is by far the quietest burner I have seen on YT
Enjoy all your videos. Keep them coming. Down side for me is no lathe or milling machine.
Thanks for the video but wow.man you have all the good tools!
Muy bueno el vídeo, es muy clara la idea te felicito.
Professional Solution! Thnx for sharing!
Very impressive im gonna read more of it thanks
Cracking video Sir.
I just made one today similar to this which burns compressed natural gas which I stored in a propane tank.
Very nice work. Clearly "for the love of the build"...
Thank you master!
Loved it ty my good sir
very good video and making the coke can shim was good idea
gr8 vblog thanks for sharing, I'd use a propane weed burner bought with chump change
Nice tip on the white out (typist correction fluid) I will have to try that one out. The next time you anneal copper try plunging it in water after you get it red hot. I think you will find it gets softer than if you air cool it.
8
That's a well-known fact. Copper is the only material that behaves like that, as do some copper alloys. I actually apprenticed in metallurgy so I know, and my teacher was an artisan copper sculptor.
Just finished watching all 44 videos in the casting series. Well done, and greatly appreciate the effort that went into making them for us.
Three questions:
First, when do you prefer Petrobond/oiled sand vs. green sand? Seems like a fair amount of work to condition the green sand between casting sessions...
Second, what's special about core sand?
Lastly, what do you think of electric kilns vs. propane for melting aluminum and brass?
Thanks again,
Tom
Thomas Utley Petrobond gives a good finish to the casting and is easy to use but it is expensive, you loose a bit of it on every casting as the sand around the metal bakes hard and has to be removed.
The core sand is just a silica sand that is dry, no clay like the greensand.
Electric will melt well and is a good atmosphere, no gasses from the burner but it is slow compared to gas. I think it took about an hour to melt the small amount in the video on brass and petrobond.
Bravo!
interesante mis saludos desde venezuela
Genial!
Muy bueno y didácticos
THANK U
Excuse me, which is the brand and model of your metal lathe?
Always nice to watch your videos . I did watch them all! Would this gas burner be good for melting bronze?
I have melted brass with it. If you look at some later videos I added a blower which increased the output.
Life tip: instead of Coke can use any beer can.. much healthier and better tasting
phenomenal job mate. just wondering about the importance of the flare. you said that it is required when burning outside of the forge but how about inside?
No flare is needed when the burner is used in the furnace.
thanks mate
unless the codes or colors are different in your country, you need YELLOW GAS rated Teflon tape when dealing with seals of this nature.
Do you think an aluminium chimney duct with refractory caulking on it would make a good vessel for casting? What would be the possible problems? I'm looking at making a cheap charcoal/propane burner with one, just not sure as of yet.
No, I would use a stainless steel storage container without any coating. I used these for a long time. They have a short life but are easily replaced.
Beautiful build ! What things are you making with your set up ?
+Michael Benjamin Here are some things i have made ruclips.net/video/_OwYCGlYLUk/видео.html
Muy bueno
thanks
good listening
super
Молодец!
I enjoy your site. Sit and watch with cup of coffee. Good way to start day.
One problem I have is Metrics. Old southern boy here and only know SAE. Is there a chance of also stating these in SAE to or do they not enter-change that way?
I was using standard UK pipe fittings which are metric sizes. Easy way to convert is to Google "mm to inch" for lots of conversion aps.
I want to know everything about the blower. I've seen a whole bunch of burner designs, but the blower - wow, that blows my mind. How much more effective is the process using a blower? What is the blower design?
GrayCoLLC You can see all about the blower in this video Metal Casting at Home Part 44, Propane Furnace Burner Improvements.

New shoes!
👍👍👍
suprized i didnt came across this one sooner , seems like a verry "civilized" burner its a verry simple design (yeah you need a little more tools to make it ) , and gives off plenty of heat without the noise anoying the neighbours or using a large amount of propane for a 10 minutes shorter melting time , wat type of blower did you use , it looks like an old electric paintstripper
Yes it was a hot air gun blower.
QUESTION BUD.? What size bit did u use to drill the gas jet hole. A 16th, im from the US so i dont no if I said that right
I used 1mm, that's 0.039" or # 70 drill. All the dimensions are here myfordboy.blogspot.co.uk/p/myfordboys-furnace.html
8:00 how did you get scissors sharp enough to cut through a soda can?
I've tried sharpening different scissors with a bench grinder and I can't get them sharp like I've seen on youtube.
+CallMeBronco Cans are very thin, any pair of scissors should cut it easily.
You can't use JUST the bench grinder. Use that first but then polish the edge with a hand sharpening stone. You can also use a ceramic nail file (not the metal type). With the bench grinder you sharpen it up-and-down, but with the hand one you do it left-and-right until it's completely smooth.
Also, needless to say, you only sharpen the slanted edge, and not the straight edge of each of the blades.
Yes it takes a while, but you'll know you've done it well when you take an axe blade sharpened the way I said and shave your arm hair off with it.
I sharpened one of my favourite swords this way. Took me days but you can do this while watching RUclips lectures. Just be careful. But yes, you can actually shave your face with that sword if you wanted to. The real test for that is cutting small wet branches in your garden Zorro style, which I've done.
What makes the clock a noise?
شكرا
What was that ghostly whisper at 7:59? Spoooky...
Everyone farts now and again (lol).
just a hint ,, if you use a .30 tip for a mig welder you don't need the brass disc. different size tips produce different flames

What kind of torch do you use for silver soldering? How hot does the metal need to be to solder?
I am using a sievert propane torch. for silver solder the metal has to be around 650C which means for steel the metal will be red hot.
Brass, aluminium, steel, copper, and silver, couldn't you have fit titanium and zinc in there somewhere? :)
W Bailey 😬
W Bailey سبامليظ،فل
ZINC when heated to vaporization (less than steel at cherry red), produces arsenic and other toxic fumes... jus sayin.
Michael Rinkle So when you heat up zinc it becomes a different element? Interesting.
and maybe uranium
hey, i have made a burner like this, thanks to your video! it looks awesome;)
Only one question remains. i now need to get an adjustable pressure regulator to control the flame. what pressure range do you recommend? i have been looking at one wich has a range 5 - 20 psi in 11 stages. or 0,35 - 1,4 bar if you like. thanks in advance for the reply:)
+Actionhank You need more pressure than that. I run at 2 bar, one that goes up to 3 bar would be the best. The type sold for caravans or Bq or not high enough.
+myfordboy thanks for the quick response :) ill go with one that has 0-4 bar pressure and a manometer. since it will be the easyest to acquire. thanks again :)
By using forced air with in the torch or not, will that effect fuel consumption and how?
Forced air improves combustion, heats up quicker so saves fuel.
14:44 copper being an extremely good conductor of heat it would have been better to add a heat sink to the side with the joint that you wanted to protect. The insulation as shown in the video will only help contain and transmit the heat via the metal. It would protect the joint against radiative and convective heat transfer, but these modes of heat transfer in all likelihood play only a minor role here.

big bullet casing not a lot easier?
We need Disel burner. Which can gives temperature 1700 or 1900 degree centigrate
Did you make the flare yourself? I'm betting you did so did you just 'eyeball' it or do you have a rough estimate of what it should be?
joseph perry It's just a rolled up tin can, nothing special.
I have the burning need of making my own furnance and cast some aluminium, this is amazing but maybe im an ignorant but wouldnt be alot cheaper to use some bought gas regulator and burner?
I don't know if you can actually buy a burner like this but mine is very cheap to make. The regulator on the gas cylinder is a commercial item.
or a large enough drill will work as well.
Mr myfordboy, I would like to know if this furnace set up well melt iron? Thank you.
I have never tried this one on iron but I doubt it will. My oil fired one will though.
Ah I see. I was hoping not to go that route, gas is much simpler and cleaner. Would it be possible to double up the propane and make it work? As in 2 burners form opposing sides. Thank you.
I would not go for 2 burners but forced air helps ruclips.net/video/ZjGT8ZAVnts/видео.html
Nice! The forced air improved the flame by 2-3 times. I still have more to learn before making one. Thanks you sir.
Hi there myfordboy. Iv just made a furnace burner but it's a massive FAIL. It's made from reclaimed bbq parts and a standard gas bottle valve.
It's on my channel
Can you take a look and see where I have gone wrong and maybe recommend what part in need to replace.
P.s I am UK based over the water from Liverpool.
Thanks
Great video, is the Stainless pipe just 316 water pipe 1.2mm wall?
+Bob Smith It was just some pipe I had. It's not critical, water pipe is fine.
+myfordboy Thanks for the quick reply, do you think adding a sliding gate over the inlet would be suitable to add a degree of temp control, say for use in a blacksmithing forge, I really like simplicity of your design.
+Bob Smith The air does not need restricting any more. In fact the burner worked better when i added a blower to the furnace ruclips.net/video/ZjGT8ZAVnts/видео.html
+myfordboy I see what you mean, thanks agian for taking time out of your day to reply.
I will he giving this burner a try.
I did not know that tippex did that (mind blown), anybody know why this works?
What is the diameter of the gas jet hole you drilled?
myfordboy Need to add a "d" to the URL you have listed here and in the description...
Best Racing Tips Win At The Dragstrip I have listed all the dimensions at myfordboy.blogspot.com look at the bottom of the furnace page.
Robert Jochim Thanks for pointing this out. I have corrected it.
hi sir do you have any video on how to build furnace and how to make the crucible? thank you
I would not advise making a crucible you don't want it fail when full of hot metal.
Go to myfordboy.blogspot.com for furnace building details, there are links to the videos there.
myfordboy yap i agree with you, i am afraid that my diy crucible will fail, do you have better idea rather than make my own crucible sir? thank you
Why do you use silver solder and not lead solder?
Green Silver Silver solder is stronger has a higher melting point and makes a better job. The soldered parts do not get hot so you could get away with soft solder.
Thanks for the reply, I've noticed in a few previous videos and wondered why.
Do you made this burners for sale? I need one to melt silver
+Ricardo Murua Sorry I don't have any for sale.
all of your videos are great and i very much enjoy watching them all. I however have a question i have not seen any of them where you are discussing anything or explaining anything i don't think i have ever heard you speak a word in any videos i have seen. Just wondering why? Wouldn't it make it simpler to explain about what is going on while the video is being recorded instead of editing the video to include written text on what is taking place at a given time in the video.
Tony Emory It has become the style of my videos that I do not speak. Many viewers like it like this with no waffle or stumbling speech. It is difficult to talk and work at the same time.
That makes sense, Thanks for the videos they are very informative, On this particular video how is that burner holding up for you, I built a Reil type burner but for some reason i cant keep the flame in the furnace all of the time, Sometimes it will jump back down the barrel of the burner a few inches and works way less effectively. I was concerned the flame would follow the gas back to the bottle the first time ( i know this is not possible but for a split second i though oh crap) My other concern is i may have been a bit overzealous when i built the furnace as big as i did and that could very well be the issue, I am in the process of reducing its height by 8'' as i never have needed that extra space and don't anticipate needing it, I have the diameter i want which will hold my crucible that is about the size of a gallon paint can. For me that is more than enough molten aluminum at one time for my needs. I do sometimes tend to overbuild some things but that is due to not wanting to have to do it a second time because the first time was either to weak or small.
Tony Emory I have not had any problems with this burner, it works very well. In a later video you will see how I added a blower and this reduced the melting time. I have now switched to waste oil for fuel so have zero fuel cost and can now melt iron.
Very nice. Myself i dont think i will ever be melting iron but you never know what i might need down the road. Think i will build one of your style burners and test it this weekend. Thanks for the information and the time.
Tony Emory The burner details, along with my previous ones are shown here myfordboy.blogspot.co.uk/p/myfordboys-furnace.html

Isn't all tape sticky ?
I thought that unlike steel, to anneal copper you heat it until red hot and then quench it?
With copper it makes no difference. You can quench or let it cool slowly, it will always be soft.
This is too much, not everyone has a lathe. Us farm boys have been building propane burners from the time first weed grew. A grease fitting, remove the center with a punch, a few pieces of pipe and you have a burner. this is a lot of crap and work. You can figure it out at the hardware store, all of your grease fitting are pipe threaded and they come in a nock in grease plugs for the ones who cant thread steel and weld.
Why does your lathe make a ticking noise when it stops?
When the motor slows down after the power is killed the centrifugal switch inside the motor clicks as it reconnects the start winding ready for the next time it's switched on.
ahh cool. Thanks
myfordboy How can I cast things with fine detail? I've heard about using Hydrocal, Ultracal 30 mixed with Silica Sand or Silica Flour. Can you cast things with fine detail with Sand casting? I would like to get into metal casting, but I'd like to do things with fine detail. Your videos are very inspirational. Thank you for sharing your knowledge of sand casting with us. It's very relaxing & reassuring watching you cast many different things & parts using this method. (+1 : 342)
I can see why nobody's responded to your post for so long because there are so many different variables involved. Like, what metals/alloys are you using. What are you making? Is it art or is it utilitarian? If so, what kind of tolerances are you looking at in terms of thermal expansion, stress, strain, ductility. Usually, fine, really fine sand casting is done for stuff like bathroom and plumbing fixtures cast in brass and chrome plated.
If you're using sand, is it for making multiples of an existing item or part?
Are you sure casting is what you need versus machining?
I've had surprisingly good results using plaster casting for one-off parts, like back in the day when I owned a Citroen AX and needed to make the rear door lock release/activation pin, which was originally made of plastic. New one would have cost me 1500 RUBLES! The rudeness! I said no, but I borrowed the part over the weekend, made detailed impressions of it in plaster in 2 dimensions, then returned it, after having made a successful casting in ZnAl. Total cost about ZERO RUBLES + my time. I used ZnAl alloy from old door and window handles to make it and did it all on my kitchen stove.
Hai sir what type of fire blanket(white ) you are using ( at 14:40)??? how can i buy them ???
+mathew stephen It is ceramic fibre, not a fire blanket. You get it from a foundry supplier like artisanfoundry.co.uk or pottery supplier.
thank you very much sir for your awesome replay. Indeed i like your videos ... and gd bls U
kept waiting for you to loose your wrist!
