DIY Foundry Crucible Furnace




What do you think about this video?

G11B: Not bad. I do have to say that during assembly, it would be beneficial to seal it with refractory mortar. You're losing tons of energy (and gas) without it! The con here is that it would be a solid structure afterwards instead of something you could disassemble. But you would get higher temps quicker and with less energy if you did. It's a worthwhile trade-off. I bet you've redesigned since 2010. ;)

Brent Wiseman: Awesome design. Beautiful ingots as well. Though, with all the foundry YouTubeing I've been doing recently, the one thing I didn't know much about was the crucible itself, which is what led me here, but it's also nonexistent in this video. :p I'd be interested in what you used.

4Maestro1: DIY? You fooled me by the professionalism of the design/mnfr of the product, as well as by the quality editing of the video. Great job! Certainly an inspiration to other DIY-ers. Just wondering though... For those who are not as handy in making things of this nature, do you sell this in a kit, or would you be willing to? And if so, how much would you charge for it? Thx!

Sean: +Designsbyg Are you an engineer? I've always felt like my ambitions are held back by my knowledge. I wish I had that "knack" for problem solving a lot of engineers possess to design things like this on their own. Great project man.

dayvon cyler: I love this furnace but the thing is, I'm trying to make a furnace you'd be able to make at home, with CHEAP THINGS not fancy shmancy shtuff, but I admire it for being aweseome

ethan sanders: why the bohemian rhapsody.

Justin Gould: That's a beautiful piece of work. Superb engineering, and the most beautiful burner I've ever seen.

jlsoldwood: Would you Cast the concrete pieces ...and sell them to me?

Cheyne Simons: nice video

Tim Fox: Wow, I'd pay for a set of molds.

Don Foster: Excellent design. This is the best I've seen. I'm going to replicate for my foundry. 

Rodney Jackson: I would like to know were I could get the plains for the furnace

74KU: wow now mine looks crap..

Sebastian Robledo: how much prolixity, I congratulate Mr.

macaulayman: That is a very clean looking furnace . Have you ever tried to make refractory from perlite and refractory mortar?

FEEL DIBEN: simply awesome!!!! Thank you for sharing this model with us 

Marius Kraft Bøhmer: Sweet :-)

oodimvale: thanks....good.... São Paulo - Capital - Brasil

iROBODUDE: best home built on youtube... by far. GREAT VIDEO. I would have loved to see your crucible though and maybe a pour or two.. 

John Hauserman: can I get a set of prints for that burner it looks like it mixes very well. thanks, john

ahyaok100: thanks boss

Megan Moore: wow i'll take one. that looks awesome. well done sir.

Daniel Harris: very nice for your first try, you did better than me

fm1224: very nice!

Sho81: Really good design for the moulds. Have you ever thought of talking to the shop about a small time manufacturing and sales?

Michael Delaunay-Belleville: I believe that this is the furnace I am going to build. It is just so professionally done. Good job. 

DTLSchiller: Where is a good place to get refractory cement? I can't find any at stores in my area.

raunwynn: Awesome!

kevlauenterprises: Would you be interested in making a few of those side molds and top molds for a fee? I would love to be able to make these blocks but no way to make the molds!

Zach27: love the music choice made my morning

Asylumescapee69: You should sell the molds for a fair price...

ZebbMassiv: what is the point of melting aluminum? to sell? how much money is involved?

GrayWolfPictures: can this get hot enough to melt copper at almost 2000*F?

Mrflashlite: Hi, great job. i have been a millwright for over 30 years and love to see people take the time and pride to do things right. I was thinking of building a furnace similar to this one now that I am about ready to retire, did you use plain refractory cement or was there some mix of perlite or something else? Alot of people are comenting on the expensive tools needed but I think most could be able to lay it out with a router and circle cutter now that you put the idea out there. Thanks job well done

Cory Adamson: Do you have a link to the specs/plans? I'd really like to replicate for myself

Brad K: Very very nice job. That gas grill looked a little intimidated by the testing of the burner.

Designsbyg: @agentxoo7 - This design was purely experimental. The nozzle was inspired and based on a typical propane torch design. This is the only attempt made. There was no trial & error involved.

Bleriot529: Brilliant! "Better Living Through Science!"

amaedesign: Beautiful design! You could, of course mount the whole thing on a custom cart and it'd be easy to move by one person, without the setup required.

Cade Scott: Very impressive to say the least..! Thanks for sharing.

Pip Lache: @STRIKER520 Dude high tolerances aren't needed here, not even thousandths of an inch. The Babylonians were making glass & Bronze stuff back in the day & they didn't even have store baked buns... (Jack in the Box anyone?) doing it super cheap just purchase a $5 jigsaw at the local pawn shop & go to town with wooden pallets... (an angle grinder will probably be needed later too) Of course with my wood shop I'll use a few other tools...

joshmnky: I found some plans for an electric foundry on a site called Dan's Workshop. There were a bunch of websites of people who had built one, so I bought in. I'm going to get started this afternoon buying materials. The best advice I think is to use firebrick for the inner liner. Refractory is a great insulator, but chips really easily.

gamo98: why was the music put on for you could not hear what he was saying

oneyaker: Very nice and also probably the most expensive DIY furnace out there with the machined acrylic molds. Perfect accuracy though.

513bam: @Designsbyg Great Job!

ruow2000: @Designsbyg, Thanks for your reply, really appreciated. Wow, that's a lot of refractory :o). Again, wonderful furnace you designed.

MrMinimalSWN: Hey, I'm planning on making a double-wall-structure forge, so I can put wood in between the 2 rims for drying the wood (first step charcoal making), I would also use ventilation with a condensator and filter so I don't breath these fumes when I'm working. Now what I need to know is: 1) If the wall would conduct enough heat for the moisture to evaporate from the wood? 2) what's minimum thickness the wall should be for a save forge? 3) Wich brand is that of the product you're using? Thanks, greets

Designsbyg: Although i've not tried it yet, i'm very confident that it would easily melt any non-ferrous metal. When I run it to melt aluminum, i'm only running at about 10% throttle! It was designed with melting bronze, brass and copper in mind. I do intend to melt these in this furnace at some point. It will also melt silver/gold just as easily.

HarriMerivirta: Next step sancasting. Would be interested in knowing how you built the burner.

honse246: Very cool! Would you be willing to send me the cad drawings ? I'm trying to make a furnace and need something to at least look off of.
