I built this style in a 12" diameter steel pipe, with 2" thick cement walls, so an 8" diameter inside. I successfully forged commercially for several years. I used it horizontally, and it was perfect for long and localized heats. I even forge welded in it. If I wanted a more controlled heat, I put firebrick at either end. One or both ends, depending on the work.
Bravo.......im building one to.......ii can smell the grinder from here.........note to all......metal cut blades is made fiberglass .......wear a mask..........i don't what age u r.......cheers
Considering that heat rises, no real need for a 4 inch base. Hopefully , upon first firing when the vermiculite expanded and exploded the concrete filling, no one was injured.
@Wayne Earls I Have built a similar homemade furnace, and bought a Graphite crucible, which i see turns red around bottom after 10 mins, My question is When burning the aluminium cans they or just turning to dust or oxidising i put in around 18 an no aluminium at all? Can you tell me what i may be doing wrong... The cans melted and got really soft to keep pushing one on top of each other but yet after 40 mins coal was burning out and nothing but ashs left in crucible?
Keep adding more wood, mesquite, yellow pine, pine knot, and cedar excellent woods to use, also use a blower to increase the oxygen buildup= +× more heat buildup!!
Do not use cans. Once a can is melted, it is like a drop of aluminum. I use old and broken aluminum car rims. I cut them up with a grinder into a size that will fit into my crucible.
Unless he spoke afrikaans language and he mixed his words. In afrikaans we use the word smelt. Just a s infront of melt and it means the same in afrikaans. :)
@@WayneEarls haha. I replied on the top comment that was made of the guy saying : " its a melting furnace not a smelting.... " my comment is based on those two words.
Vermiculite expands to 3x as it's water retention media for plants. What do you think will happen when air displaces the water content? What happens when the trapped air heats to 1000°C+, my guess is it'll blow holes in the cured concrete from the pressure exerted. What I would be using is a quatz based *silicon sand* mixed with *Limestone* and *refractory cement* smeared over a Ceramic Fiber Wool Blanket reinforced by steel mesh then another layer of sand / lime / foundry cement mix with 1/5 part perlite. With an air channel running against drum and steel mesh leading to exhaust air inlet to maximize efficiency. (Although the air channel isn’t necessary it just transfers some of the thermals back into the furnace) The lawn mower base is a good idea though. Your mix is like a bomb though very dangerous waiting to explode. haha. Must have shit yourself when the foundry shattered?
Honestly I've only fired it twice since I built it. I have been busy. I have plans to get it going and also my small one real soon. I used vermiculite because I've seen others use it. But either way, I'm going with ceramic wool and refractory cement from now on. Thanks for the comment, I'll be sure to stand clear while I fire it a few cycles.
With all 4 items in a mix of cement with sand, lime, and perlite with your type of cement mix what would be a good ratio of 1 bag of cement and what type of cement would you suggest using? could you elaborate on this, need a an individual with needed experience so i can form my own foundry and or forge pit made from river rock and fire suppressant concrete mortar.
Man I wish this god forsaken country that I live in wasn't so strange to common hardware materials such as these, I literally have to buy all of them online...........
I bet it's the UK. You can't buy ANYTHING here. Everything has to be online. Forget anything and your project is delayed by days. Obviously you have every day life to do to, so by the time your stuff arrives you may not have time for your project. Then you finally get a free day for your project and you realise you need something else... OK see the project in a few weeks. It's so shit here.
I think it was 2 bags of concrete and 5 bags of vermiculite. It may vary with the size of your forge. I have a nice little one I redid for future videos so sub and come back. Thanks or watching.
It's fire resistant and supposedly adds to it's size while not adding weight. vermiculite weighs nearly nothing. I can't say it was a big difference though. It's still heavy.
I can't wear my high heels to work in either. Too wobbly. Thanks for watching! Check out my other cooler videos with cannons and guns. 3D printers and such.

Part 2 was taken down as the heat built it caused a stress -pressure reaction and the lid exploded killing him instantly. Was a great vid!
Lol thanks for watching!

I always tell my kids that as I’m standing in the concrete dust plume. Don’t breath this children. 🤦🏼 Great short video.
Never breathe any type of dust particles. It can't be good. Thanks for watching.
Awww, I wanted to see it fire up
I wanted to see the cement explode.

@@ΠατεντεςστοΜηχανουργειο That's not part 2 of this video ..piss off with your crap
It exploded. No part two.
Finally a refractory mix that isnt plaster of paris and sand
well went back to find firing video and maybe I just missed it? either way looks like I could probably get lost on your channel! lol :)
Good work ,thanks for your kind information
Nice job, it's not a smelting furnace though, it's a melting furnace, smelting is extracting metal from the ore
Thanks for clarifying that. And thanks for watching.

55 gallon or 30 gallon drum?
30
Great crucible turned out!

I like to learn more about the D i y business and be self employed. Show us more. Thanks.
Did you also make a lid?, and is it coal powered or gas?

Would the moisture not just escape the concrete? It is porous after all? It might crack but I can’t see it exploding

Thanks. Good information
Hi, any videos of you using this?
mine produces far too much ash keeps giving me loads of alloy rich slag.
How about showing cost of materials next time please
A little word of notice, " Dont use concrete it can go explowey from the water rapidly in it"
Then what should be the best option ?
That’s why there’s no part 2 !!! Iol.
@@johnsnyder2007 What should be used instead of concrete,then?
Well, that's why you heat it up multiple times before using it. To dry the water out.
Can you make a tutorial on how you made those awesome cutoff shorts?
Sure. Would you like cheeky shorts this time?
What is the life expectancy
brilliant show there Bud...
I'm just curious, but isn't it supposed to be perilite, not vermiculite???
I guess you could use either. Thanks for watching!
Oops guess I’m screwed I’m already missing a finger my channel is nine finger mining 👍🏻cool video
Why do you wear the blue and green clothes?
They protect from sparks and flying debris.
@@WayneEarls
Thank you
Doesn't vermiculite have asbestos? o.o
Lets see it working!
Lol
You have 13 thousand subs dude . Thats cool.
18,000 now
It’s Hard to cut it because your cuting disk is install with a wrong side
you just save 500 dollars. forge furnace costs that much if u buy
What was the mix on your pour?
I think it was 2 bags of concrete and 5 bags of vermiculite. It may vary with the size of your forge. I have a nice little one I redid for future videos so sub and come back. Thanks or watching.
I'd rather just use a spy camera sunglasses for these kind of videos it would be easier dont you think
He left the store without paying.
Needs insulation. Concrete by itself is wasting heat.
I shouldn't have been an ass.
I'm no better. I take that back
What size is that drum? it looks smaller than a 55gal?
It's a 30 gallon drum. Thanks for watching
Needs more water. 7:20
Could you melt iron in this?
I would have used the top you cut off to mix in...
Hell yeah!!

30 gallon drum

Where did you get 30 gallon drum? Thanks
@@catholic3dod790 I got it where I work, but you can order them from places like Uline or eBay
Is it with cement
A mixture of cement and vermiculite. The vermiculite just makes it lighter and is more resistant to high heat and cracking.
does it pay or even break even?
It's just a hobby. My TH-cam channel pays so I guess you could say it does
@@WayneEarls how much does it pay?, curious here thanks!!
all you need is 8 cobble.
Bro I need the other part of the video to make lid and for gas connection...
It didn’t work it blew up he was killed :(.
Just kidding I want it also
Why vermiculite?
It's fire resistant and supposedly adds to it's size while not adding weight. vermiculite weighs nearly nothing. I can't say it was a big difference though. It's still heavy.
How long did/does that foundry last?
I fired it twice before I got too busy to mess with it, but I'm about to start up again. Thanks for watching.
Nice shorts
Thanks. I didn't want to wear my church shorts to work in.

Never made part 2 bro
is that non asbestos vermiculite?
I thought cement was a big no-no?
Yea. Im confused now too..
Buy a bag of refractory cement/mortar. Good up to 2500 degrees. You are right, do not use cement.
I'm in Home Depot share and subscribe 😂😂😂
