Replacing The Ceramic Wool In My Devil-Forge FB2Mb Furnace - Scrap Copper Melt - The Growing Stack

[@TheGrowingStack]

I’ve been putting off re-wooling my furnace for a while now. After doing it, it’s pretty easy and cheap to breathe new life into it. I hope you enjoy this one and have a wonderful day!

[@derrickginkel9431]

Why don't you pour the bars to the top of the mold?

[@gunnerroo6514]

I just wanted to say thank you for making this video. I have always wondered what the process is like and yeah I would put it off too. Thanks for the cool video and chill vibes!

[@PYROxSYCO]

I bet it felt like you were firing it up for the first time! Have smeltinga

[@ValikFellbane]

@@derrickginkel9431 It's easier to remove the bar if it isn't poured to the top and it cools a lot faster because of both the less metal and the mold has a "Release Point" for the heat.

[@ValikFellbane]

Have you tried putting a piece of cardboard between the fire brick and the crucible to keep them from sticking together? I noticed it stuck during your massive can melt.

[@lichtheimer]

Do I own a furnace of any kind? No. Do I plan to start melting things to turn into bars and such? Also no. Did I watch this because I've watched videos using these things before and was curious how weird it could be to re-line a furnace? Yes, yes I did. Also: The simple mechanism to keep the crucible held while pouring while also putting something between it and you gloved hand is just fantastic.

[@bbo4300]

That's the most precise pouring I've ever seen great job wow

[@lisazdankiewicz8846]

I have seen so many vids where people say they need to do this. I have never seen it done though !! I actually enjoyed this video. I got to see how its done and what it is made of. Great idea for a vid, thanks for sharing with us !!

[@SkullerMetals]

I'm a Michigan native - love your icon!

[@jamesdewaal5558]

I've watched nearly every vid on KZbin about smelting and for some reason never saw you until today. I must compliment you on your castings as I can see you take care to do it right and neatly. Most of the other youtubers just rush through the process and cast, even if their casting looks like s*it. Thank you for taking pride in what you do and the end result of your project. Keep up the good work. Respect.

[@zazz69ed]

looks like she was about due a change on the fire brick and wool.. LOL another great video my friend and stay safe.. much love and respect.. catch ya on the next one!!!

[@nathanward4331]

That cut idga in the lip of your crucible gives a perfect pour. Never seen a crucible like it. Amazing.

[@sisyphus8870]

Your pouring is extremely precise.

[@catgynt9148]

Thank you for sharing this insightful video and specifying your use of safety gear. Wishing you and your family a blessed week, gentle weather and restful evenings. Peace brother

[@weldingbiker1]

Love the video, here in UK Amazon the same ceramic wool £155. Very instructive and informative. Please keep up the great work.

[@NinjaWeazel]

I was just wondering when this was going to happen, while watching another of your videos a few moments ago. Good to see it looking all refreshed and ready to burn.

[@neotericsilverstacker]

Always enjoy watching an artist do his thing!! Thanks for sharing!!

[@tonin7279]

So fascinating to see! I really love the things you make of copper best so beautiful when buffed.

[@JsStack]

Nice work. I will need to do my Devil Forges sometime. Great melt and pour.

[@theboogeyman2229]

Best type of videos on KZbin change my mind

[@Mark5mith]

Hi, glad you mentioned wearing a mask, I'm an insulation engineer, once ceramic fibre was exposed to anything over 600oC we treated it the same as asbestos, it's great stuff but not for breathing in.

[@adamc3474]

Thanks for the video. I'm considering getting into melting and I like knowing as much as possible before I get started. This was a big help. Stay awesome.

[@danaedwards5464]

it amazes me how well the wool holds up for the abuse we give it and some nice pours you have a steady hand

[@bluegreen2360]

Lookin good. Word of advise I use a cheap $1 spray bottle from walmart to apply my rigidizer makes the job go that much easier.

[@timsmith9645]

Awesome coppers coins and thanks for showing us how to rewool the furnace and thanks for sharing

[@mattyal9347]

I never considered putting the seem at the inlet hole. You can bet I'll be doing it from here on out! Nice!!

[@timrockman7]

That looks like fun! I built dozens of crucible furnaces from the ground up, but never used one.

[@SeanBrown22]

Nice! That rigidizer looks like it was a lot easier to apply compared to the refractory cement stuff that came with the devil forge. It didn’t seem to want to stick to the wool when I painted mine on.

[@TheGrowingStack]

It is a lot easier to apply, probably not as resilient as the refractory that comes with it, but it will hold up decent enough depending on how much and how hard it’s used and abused 👍

[@daz41262010]

great video bro :) your pouring skills have improved so much from when I first watched your first ever videos :)

[@brettlejeune7009]

Dude that furnace looks really good, awesome job

[@gunnerroo6514]

I always wanted to see this process so thank you!

[@lesliek3794]

Ok, so don't take this the wrong way, but I've never really listened to the music until you said each video has a different one. HOWEVER, tell your brother, he does a great job with it. Yep, I like this one too. 😎 The lining looks great, it almost looks like a new furnace, but I think your fire brick is defective. 😉 The coins look great! Congrats on reaching almost 50K. Won't be much longer till you reach 100K.

[@TheGrowingStack]

Thank you as always Leslie! I love your feedback, I really do. I will definitely let him know. He spends a great deal of time and work on the music to make something we are both proud of. He does an amazing job and works diligently to make things perfect… even if I sometimes screw up and use a sample he sent me instead of the final polished product by mistake 😬 (that’ll be our little secret 😉)

[@joigalha]

Thats awesome, just shared to a friend who's always wanted to build a smelting forge like yours. 💪🏽💪🏽💪🏽

[@foxwhiskey]

Hi. For cutting glass-wool or sth like that I'm using an electric knife (directly "stolen" out of the kitchen). The results, especially the edges are excellent. Best regards and greetings from Germany ! 😃

[@demigoddragoness]

An old Bread knife will also do very well so long as the serrate isn't too pointy.

[@mrrberger]

Herby you live on the edge of danger with that advice.

[@foxwhiskey]

@@mrrberger please an explanation. I can't see any danger. During cutting the environment and the air stays clean.

[@mrrberger]

@@foxwhiskey.... unless your spouse catches you with their bread knife. Then neither your environment or air will be clean till they're finished venting on you.

[@SJWCASTING]

I need to do this myself asap!! (Saying it for months😑) Great video man! Love the coins! Been a subscriber for a while now and your channel is doing great!! Keep up the good work!!👍🏻

[@shermantripp5246]

i just got done redoing mine as well with fireproof insulation from amazon

[@tvviewer4500]

[@noiscafundindojonnyemonie]

Forja renovada com sucesso 👏👏 ai sim 👍

[@grantus1231]

Great video, I've built own furnaces and I only ever used refractory cement, never knew you could get a rididizer for the wool. Will look into it, Shot my Guy.

[@timrockman7]

The rigidizer is probably sodium silicate. When I made crucible furnaces, we casted the base in high density castable refractory and the lid ring with a lighter mix that was reinforced with stainless steel fiber.

[@vincedibona4687]

I like the last, “unfinished” coin best. 😃

[@tracybowling1156]

Hi!!! How are you? I hope well! I loved this video. Do you know why? I liked when you cut the insulation. And when you did that fancy math 😂. It looks great. And who can pass up watching metal melt? Not me!

[@brendacolter368]

I thought I was the only one who loved copper melts. Have you ever thought of selling your amazing work? It keeps getting better and better. Make a way we could buy some of it, just an idea. Thanks for sharing another great video.

[@TheGrowingStack]

Thank you Brenda! I’m still mulling around the idea of selling and the best way to offer that… Someday soon…

[@MrJames0825]

Great video! Never seen how you replace the insides and always wondered! Thanks for sharing TGS

[@brandt-heiss]

I love those copper coins... ❤❤❤

[@erumara8584]

[@doriWyo]

I know very little about the furnaces, but this looks like a great job!

[@TheGrowingStack]

Thank you Dori!!!

[@rashoodinhoorashood1641]

Great video 👍🏻👍🏻 keep it up

[@MrJco54]

I was wondering about the lid myself, I was finally able to coat my furnace with satanite but the blasted lid area went to hell cause the insides fell out....though I shoulda known better considering it was Always falling out, downside to buying a cheaper off-brand furnace. Did manage to melt a bunch more aluminum, got several more bars of copper, and even got my first brass bar. Going to have to rethink my surfacing on the interior of the furnace though. Thanks for this vid, gonna bookmark it to my metal melting tab/folder. 👍😎🍺

[@thunderbasilisk1352]

How often should you replace a forges interior? Also this was a very satisfying video to watch.

[@TheOverloaded1]

I am surprised. Figured you would also add a refractory cement to the outside. Guess this wool is impregnated with something that the rigidizer activates so you donned to.

[@divingadventures121]

Cool video man

[@mikiiitakaa]

This new wool look so soft, i wish i could touch it

[@ypguys]

What would happen should you fill a mold half way with copper and the last half with aluminum? Or make a three layer ingot with copper, brass, and aluminum?

[@SkullerMetals]

No one pours them cleaner. Nice job! Gotta change my wool too.

[@TheGrowingStack]

Thanks brother!

[@steviebee7036]

I was wondering from past videos about that wool and if it ever gets replaced lol... does it help keep temps higher ?

[@JimFinlayson]

Nice video and tutorial. There’s just something about that molten copper - nice camera work. Have you ever done Nordic gold?

[@tristianmershon5508]

I may be wrong, but wouldn’t putting the rigidizer in a spray bottle make for easier application?

[@RenKnight347]

Neither method of application is wrong. Rigidizer can be applied by either paint brush, roller brush and/or spray bottle. The spray bottle more than likely can provide the quicker coverage for the least amount of time. I would have used a spray bottle but soaked the entire kaowool blankets front to back then fit it all back into the smelter forge allowing the rigidizer time to cure and then apply a refractory mortar and sodium silicate (water glass) to the remaining exposed surfaces to the heat source. That stuff is not cheap so it would probably be best to extend the life of it as much as possible by taking a few extra steps.

[@coyowens5847]

Great video

[@danielbriggs7110]

Have you tried an electrical furnace ?? One if the copper coil ones like in back yard scientists video ???

[@TheGrowingStack]

I haven’t yet. I’m curious though.

[@jaimemartinez8121]

There a product called fiberfax insulation holds up to 2000 degree's .I use it to seal magnesium furnaces which go up to 2,500°and normal running temperature of 1200 to 1500°

Just so everyone is aware alway ware gloves while doing this also a respirator and vacuum/pickup all left over scrap and dispose of properly.... founders wool is some serious bad stuff. Don't let your pets around it or kids while doing this process.

[@phillipmele8533]

The forbidden angel food cake inside of every furnace…

[@jock-of-ages73]

What is the liquid that you used to harden the ceramic wool? And, does the new wool give you higher temps?

[@siggyincr7447]

I'm guessing it's sodium silicate.

[@21bravo1983]

Shelf strength over 9000 🤣

[@mistbooster]

Did You ever get around to making a big brass teddy bear?

[@Etrius_Fysik]

[@tonyanastasi22]

Does re-wooling help with the heat transfer? I feel like once the wool gets used like it was, it would take longer to melt

[@vraspus]

You have a Curse of the Monkey island interaction coin mold? I want, where you get?

[@verticpc3546]

Hey, nice video. By the way I own 2 pubs and we have thousands of cans we throw out, if you ever want them let me know. All though we are based in the UK so not entirely sure if it would help you with free supply of cans

[@TheGrowingStack]

Thank you Vertic PC, I’ll definitely keep that in mind. 👍

[@verticpc3546]

@@TheGrowingStack No problem.

[@pizzalord3n]

Mmm yummy refractory cristobalite dust... Sure hope that rigidizer works though, some brands require you to really douse the wool lol. Also edit: for the initial burnoff you should really do it in incremental increases, annealing the material over a long period to make sure the wool stabilizes and won't release any fumes or harmful dust

[@simonfung7676]

Can this wool apply in induction furnace? And how to minimising the O2 content when I cannot setup a vacuum melting environment?

[@bradschulz1224]

Huh, it's just a can and insulation...I thought it would be more complex than that, do you notice an increase in efficiency with the new wool?

[@TheGrowingStack]

I couldn’t really tell a difference. I’m not sure if it will be any more efficient or not. I’ll try to do some timing on my next melts. 👍

[@jimcirabisi]

I know you stated that you have to heat the molds to get rid of moister. Is there a safe way to show your viewers what truly happens if molds are not preheated?

[@TheGrowingStack]

I suppose I could gear up or get behind some plexiglass and see if I could get the reaction. I might try that some time. 👍

[@MarkSentMe]

Is that ceramic wool itchy like fiberglass?

[@TheGrowingStack]

No, it wasn’t itchy at all 👍

[@justinbanks2380]

Very cool. Is the hardener all you really need? I've been off making one with wool as I really don't want to deal with it. And I thought you still had to line with cement or you'd still have the danger from wool every time you used it?

[@TheGrowingStack]

I’ve applied rigidizer once in the past when the wool was looking pretty haggered to protect against the wool danger and the wool from breaking down any further. I wear a respirator when I melt, so I’m not terribly concerned until the wool starts getting really weathered, but I think a nice coat of refractory would definitely be better 👍

[@lestermagnuson939]

Hi, I am an industrial insulator, there is a material called Aerogel thinner and far more efficient than ceramic fibre new tech 1 inch is equivalent to 3 inches of ceramic

[@gigguillot4427]

Thank you! 🙂

[@Chinhnguyen0497]

[@Maro.Simone]

you dont apply the mix of perlite,sand and other ingredient for make better cover of wool? godd job

[@alquimiavsmetalica5250]

To increase the efficiency of the oven buy these things 3cm thick ceramic fiber blanket. how to adhesive alumina paste . reflantante part prefabricated alumina gloques. last lining . Jeweler's plaster or plaster but it is not any of these elements It is Kaolin clay . The squirrel minimum thickness 1.mm up to 3.00 and always with distilled water. So much clarity of ceramic fiber blanket is a high loss of resources as it is not a material with a high reflective coefficient.

[@WaxedMerkin]

I always thought it was a refractory lining

Wool? Really! Surprise me with what insulates a chamber able to melt metals to a free flowing liquid state!

[@BaconWhitEggs]

The structure of it makes it an excellent insulator it barely absorbs any heat at all. It's make from very small ceramic strands that make upp the wool. Ceramic is very tough and stand up to heat really well. It's very unhealthy though to inhale the dust(ceramic strands) from it. Especially the ones that have been burnt.
