I felt like I was watching myself in this video. Applying a lot of practical knowledge and constantly adjusting without pause because every first build no matter how intelligent we see ourselves is a huge learning curve. Every other attempt includes a necessity to adapt and continue evolving but usually most is learned at the very first attempt. Your ability to just continue without being discouraged is your real asset and makes me want to see more.
Just a suggestion: I’d have welded a shallow lip along the top edge so that when you swing the lid back on, you don’t waste time locating the lid centrally, you just bump it up against the lip and it’s there
As a teacher this video is such a great example of creativity, skill, problem solving, perseverance, and self- reflection. I know it will inspire some of my students. Great job!
On our Hot strip mill where they roll slabs 12' long 10" thick and 50" wide and rolled into coils to keep the heat in as it goes through 5 strip mill stands they used Koa-wool to keep the heat in. I could be rolled down to 1/8" thick. This steel goes through many rolling operations before it gets to the consumer. They used stickers like you did John in the vertical . You idea was right, they only used the Koa-wool with out the refractory. All it had to do was hold the heat in as the strip went down the line. At the end when it got into a coil while still red hot they would quench it with water. Very Nice Job John !!!
I lined my first home-built furnace with Pyruma Fire Cement - No wool - It had a lining around 6 inches thick. It used to develop cracks regularly which used to worry me and I'd be forever repairing them. When it came to replacing my furnace with a smart new store furnace, I smashed up my old pot to dispose of it and breaking out the old cement was a hard job (by that time it had developed more cracks), so I reckon I'd been worrying needlessly. I'm now saving up for a new one.
Beautiful! I would recommend that you either install a valve to regulate the forced air from the vacuum cleaner motor, or an electronic speed controller. A Digital Temperature indicator would also be a nice addition.
You can definitely melt cast iron with that, you may need to change your burner from propane to waste oil, or diesel, maybe K1. But it is built to handle some serious heat.
you probably could do the lid the same way as you did your walls just long sheets wrapping around it and tightly packing more layers in, would take less time cutting that way.
I have to ask because I thought I was well rounded knowing more then most about a lot of things you film. But you seem to have a much more vast knowledge of even more. Whether it be carpentry,leather work,metal work,forgery,machining,auto type mechanical and heavy equipment. And you explain yourself very well. Where did you gain all this knowledge ? You are among a few. I try to be a jack of all trades but you seem to be close to a master of all.
Just always trying new things, learning, reading, experimenting, failing, and lots of watching youtube... After many years I've picked up a few things, but there's plenty more to learn. Cheers, brother!
Great job on the water heater forge should do the job no problem, by the way I wonder if you could tell me the length of the length of the belt is on your homemade linisher....Regards Greg
I ran into the same issue with the satanite when I made my foundry. My ocd had me reapplying and touching up the cracks over and over. The cracks are just the way it is.
@@timwalton5504 not at today's prices but if they turn around and start back up yes. We are getting 25 cents a pound by me. Check out Big D stacking on utube he shows expenses by yield he even does it in Australia and dollars.
Looked thru your build, and two questions popped up in my head: 1. It lookes as if you use a forced air burner, can't a normal aspirated burner get to the temperature ? 2. The lid, are you sure that the insulation mounted the right way can hold the refractory, or do you onlu use a thin layer ? Oh and by the way, where did you get your temperatur reader ? Seems that I can only find the ones that barely copes with alu melting temperatures. Anyway interesting videos
I am planning on building this, my question for you is: Would you be better off using just the refractory paste and not using the satonite to avoid all the cracks, would the refractory paste last longer? I really enjoyed your videos!
How is it holding up, with the choices you made (Kaowool and Satantite and the HT product? And, how did the lid hold up? Did you rebuild it like you suggested? Just curious.. I am going to build one of these down the road a bit.. Been following..
Great build Man! I really hate to see how many arm chair idiots that are trying to tell you how wrong your build is. Where do these know-it-alls come from!?!!
Since your burn pipe is removable, you should really consider building an oil burner now. Lots of people out there just dying to get rid of entire IBC's full of oil out there.
Yeah we heard that same comment over and over again at our shop in Cadillac Michigan at Cadillac castings I think the company branded that we just called it Ladle wash it was the last layer starting with a bold and a portable cast bowl and vibratory tool, then a layer of ram refractory which is a clade type style that you use a air ram to force it into all of the defects of the castable and then ale to wash which is a sacrificial layer that can be replaced every couple of days!
I think you need a structure that can help life the molten metal out of the furnace so it will be easier to pour your castings without spillage due to not being able to hold the weights for very long and due to the heat of the pouring metals.
How thick is the insulation? Was it around 4 inches? I want to use a helium tank, but I think only about 2 inches of caowool will fit, and still have room for the crucible. Would that be a thick enough insulation wall?
The tube you installed to store your lid handle will make the hand portion of the handle right at the gap between the lid and the body. The handle will become too hot to handle.
What you need to do is slow down and have some patience and give that stuff time to dry on its own. You going firing it up with wet in there and you going to make it steam you get cracks blow outs etc
Instead of the thermal blanket / satanite / refractory cement, I would use old Space Shuttle tiles! Too bad they probably cost $10,000 each! But I'm sure NASA still has a box or two laying around!!! Seriously though, I once heard a story about a NASA employee who got a box (maybe defective?) and he lined his fireplace. Could be wrong, it was many years ago, but it said he got them all legal to own. I'm sure they are the same they sent to schools...
*the first layer of refractory was a mold and pourable refractory you called the mold in Grease poor the refractory between the outer shell and the inner mold and run a big vibratory tool we called at the donkey dick!! Then you pull the mold add the ram refractory as a refining the inner structure and then the ladle wash as a sacrificial layer that could be replaced every day or two or patched on-site if there happened to be a crack forming and you needed to finish out the shift with the ladle!
Please do yourself a spiritual favor, before you lock on to any view of the rapture, watch the series on All rapture views including partial rapture, this teacher IS the best by far for unlocking the truth, his name is Andy Woods and you can find him here on YT by typing his name or "Andy Woods Ministries" this man is the only one in my long search of teachers that can actually answer any questions you have, before you even watch most of them you will have discovered the true view, you can watch the areas you want like mid or post and you will see the truth
One if not the best furnace build I have seen. Excellent point with the lid.

A modest genius son a genius I tell you... Great work and skills to figure it out as you go and good job with explaining your work and steps.
So far the best video on making a furnace, Your way so far is the best way and I don't think anybody can top it. Thank you for sharing this.

Awesome job! I made a sign like you did with copper. My friend and his new wife loved it.
Brilliant job great for others to watch and learn from keep the great videos coming
Good show, I think it's going to work. I'm going to try to mix perlite In a old blue bladder tank. I'm curious to see how it will work.
Beautiful!

Nice furnace, I think I will be using some your ideas on mine when I build it. By the way your shirt says a lot too. I like it.
Thank you for the demo I am building one for my shop and thinking of using you lid set up for my forge . Very good instruction.
Simply outstanding!👍👍👍👍👍
Redesign your handle location when the lid is open, if your hand gets hot. I like your video. Keep providing videos. I hope you can melt cast iron.
This is a really cool project - Thanks for sharing your build!!!
Thanks for all the tips for when I start building mine. Cheers Stuart 🇦🇺
Looking forward to a cast iron AR lower receiver.
willy kanos they make very nice paper weights.
Wow, using a vacuum cleaner as your cyclone blower is just... awesome-nuts!
a Telescope handle is also good to lift it easyer- nice Work.
"Don't do this, this is stupid" LOL
Tempted to build a furnace. Thanks for these videos.
You can definitely melt cast iron with that, you may need to change your burner from propane to waste oil, or diesel, maybe K1. But it is built to handle some serious heat.
How about a update on our large foundry. It has been 2 1/2 years now and it would be interesting to know how it is doing.
you probably could do the lid the same way as you did your walls just long sheets wrapping around it and tightly packing more layers in, would take less time cutting that way.

also basalt mesh doesn't expand and retract. good for this application
Great job on the water heater forge should do the job no problem, by the way I wonder if you could tell me the length of the
length of the belt is on your homemade linisher....Regards Greg
That turned out great 🤠👍
Great furnace my friend! I admire your technique! Weld weld weld
You are a patient man! You do good stuff!
Hello from Canada
Great job- well done
I ran into the same issue with the satanite when I made my foundry. My ocd had me reapplying and touching up the cracks over and over. The cracks are just the way it is.
less water will result in less cracking with most refractories. unless its real high-end stuff made for dipping like the last product he used
had a question, how much propane do you go through? or rather how long does one tank of propane last?
Depends on what I'm melting and how much. I can melt aluminum easily many times with a tank. Probably do 2 big copper melts with 1 20# propane tank.
@@FarmCraft101
Just started watching your videos you said this was a Hobby so are you a machinest is by trade??
@@FarmCraft101 so can a person melt copper and aluminum to get the higher price per pound and still make money after paying for the propane?
@@timwalton5504 not at today's prices but if they turn around and start back up yes. We are getting 25 cents a pound by me. Check out Big D stacking on utube he shows expenses by yield he even does it in Australia and dollars.
Looks amazing thumbs up my friend I have subscribed to your channel and I really look forward to all of your projects thumbs up again
I hope you post some capacities, limits, and foundry techniques for this unit.
Inspiring work, that.
How readymade furnis for ceramic this size and price Indian money
Awesome job thank you for the info 👍

If you really can melt cast iron in that furnace, you HAVE to make cast iron iron sights for your aluminum AR.
FYI, out of all this water heater series I only got one notification. That being said, great videos as always
Granted it's 5 years ago, but an angled piece of pipe pair gives you a cam that would raise the lid upon rotation without any muscle required.
Hi ,why you didn’t twist the top of the hook?
I am planning on building this, my question for you is: Would you be better off using just the refractory paste and not using the satonite to avoid all the cracks, would the refractory paste last longer? I really enjoyed your videos!
I just built a burner, now researching furnace builds. The Ceramic Insulation, what is it called and where does a person obtain it?
Thanks..
Also called ceramic blanket and kaowool. Check amazon.
Nice work!
Thanks 🙏
Can your show the details of the burner and propane nozzle?
How is it holding up, with the choices you made (Kaowool and Satantite and the HT product?
And, how did the lid hold up? Did you rebuild it like you suggested? Just curious..
I am going to build one of these down the road a bit.. Been following..
I watched both and don't recall seeing how you made the burner
Great build Man! I really hate to see how many arm chair idiots that are trying to tell you how wrong your build is. Where do these know-it-alls come from!?!!
L
I watched
both of your videos,
nice work
good heat insulation
but
it's too complicated
does it pay off
so much time and work
for that ?
Can I get some information on the burner? I want to build a small foundry like that, and most of the information that I've found focuses on the pot.
Jeff Carpenter, video # 1 shows building it.
This video looks great but to use satanite in insulation sheet, is it be better to use refractory cement for total coating of this furnace?...
Since your burn pipe is removable, you should really consider building an oil burner now. Lots of people out there just dying to get rid of entire IBC's full of oil out there.
Does the heat generated from the furnace heat up the handle at all when open?
Love the foundry. Only problem for me is the amount of welding.
I think it could all be done without a welder. The lid mechanism would be challenging, but do-able. The rest shouldn't be that bad.
Yeah we heard that same comment over and over again at our shop in Cadillac Michigan at Cadillac castings I think the company branded that we just called it Ladle wash it was the last layer starting with a bold and a portable cast bowl and vibratory tool, then a layer of ram refractory which is a clade type style that you use a air ram to force it into all of the defects of the castable and then ale to wash which is a sacrificial layer that can be replaced every couple of days!
I think you need a structure that can help life the molten metal out of the furnace so it will be easier to pour your castings without spillage due to not being able to hold the weights for very long and due to the heat of the pouring metals.
could you fuel this with coal? or would you risk damaging it?
How thick is the insulation? Was it around 4 inches? I want to use a helium tank, but I think only about 2 inches of caowool will fit, and still have room for the crucible. Would that be a thick enough insulation wall?
It will work, but furnace will be less efficient, taking longer, and won't reach as high of a max temperature.
I have a beer keg I’ve been saving to make a furnace
just curious why people use propane instead of waste oil or diesel
the furnace still doing well?
great job
It occurs to me that if you put a 45° angle on that handle, when you are opening it hot, your hand won't be so close to the opening.
love that shirt at the end
Pulling that stuff apart in the easy orientation isn't also tearing? How so?
What was the cost of the materials used here?
Excellent.
what infrared thermometer do you use?
Can it do cast?
Awesome
Ha, cool music too!
next time mix in fiberglass it will reduce cracking
The tube you installed to store your lid handle will make the hand portion of the handle right at the gap between the lid and the body. The handle will become too hot to handle.
I will have the handle installed in the lid when the furnace is in use.
Terra Cotta pipe in the forge might be wise ...
use less water, and let it slow air dry to avoid cracks
The scrap makes me want biscuits...
What you need to do is slow down and have some patience and give that stuff time to dry on its own. You going firing it up with wet in there and you going to make it steam you get cracks blow outs etc
Whats that torch with the large cur conference he uses called
Weed burner?
i goona combine yours and myfordboys nice and similar
Does anyone know what music is at the end?
Subbed. Like your vids and knowledge. Regards
#FarmCraft101 , what I want to know is if you've done any cast iron or cast steel projects?
You might have been ok with that top had you not put the mesh on the bottom layer and not run the studs all the way through. Just a thought.
Head bumb at 1:17 :P
Ouch.

Beryllium is Toxic. I would be concerned that the ceramic could free some to the air.
Something tells me you're going to be cooking up a pot of cast iron in the near future.

Very nice job! i like it too much

You flipped your lid.
