Way to go, congratulations. That is quite an accomplishment. Now you can launch off into making almost anything. I have heard that old aluminum auto wheels are the best material, at least that is what xynudu says and he casts a few things. You have to be sure not to get magnesium of course. I have not come across any for my use just yet but I do like to use old lawn mower engine castings and things of that nature when I can find them. Aluminum cans are very nasty with paint and it takes about a truck load to amount to anything, same with chips from the lathe, too little material to be worth saving.
Thanks Harold! That's what I've found with shop scraps and cans, quite a bit of slag and dross, probably not the most ideal. I'm looking to come across some castings and may be able to here in the near future, the thicker aluminum cookware (especially the older stuff like pressure cookers) seems to be relatively decent, and I can find them at thrift stores pretty cheap!
Servus short question what do you use for a burner? I mean the TIG welding torch, have a very thick and inflexible hose you have a nice red little one Thank you
Haven't found a convenient work holding solution for muffins yet :P After some rough cutting with the bandsaw and some filing and sanding there was no extreme evidence of porosity, although because I didn't do a full degassing procedure and due to the source of the metal I have no doubt that if I were to use this for a machining project I would certainly find some. If my brevity made it unclear in the video, that first pour was intended to be a proof of concept of the furnace, the burner, and the crucible, and my statements in the video reflect that I honestly expected that quality of melting material to come out more obviously flawed, not to imply that I thought it was perfect. Thanks for watching!
For a cheap source of graphite crucibles check out your local machine shop for Edm graphite, we toss all ours after a burn, and you could turn your own crucible out of it
lol 7:55 its dangerous to poor molt nmetal over concrete or cement because it holds moisture and if you spill any it will explode all over the place... haha wish some one told me that mid winter 2014 when i first started foundry work and my half cut fire extuinguisger crucible leaked all over my freezing cold concrete drive way. Oh i still bare the burn scars today!

You just quadrupled pressure cooker sales at thrift shops. I am going to start looking for that myself.
You continually impress me. Impressive and thank you.
Thank you very much!!
A tip for the Tig welding... Get some smaller filler rod 1/16 or less... Thicker rod chills the puddle and is tricky when you are learning..
Awesome! loved the crucible idea. incidentally, how are they holding up? is it worth going for graphite? trouble is i can't get one large enough.
that is fast heat up ! AWESOME BUILD ..

Thank you
What materials did you use to make the oven?
How is your mortar mix holding up
Looks like a successful build - good job.
Thanks Lee!
This is a good entertaining & informative video. Thumbs up!
Have you machined any of those cast pieces? In my experience porosity isn't obvious until you've actually machined the surface

I didn't know that, that's genius! I actually have a few uses of graphite I can think of, I'm going to have to look into this, thanks!
how long these refractory keep up? portland cemento normally not work great with heat up
el cemento en altas temperaturas explota, no lo uses para esto
Very Nice... I really enjoy your videos
Awesome man. Love your videos
Thank you, that means a lot!

Nice work. Wish I was closer I would have helped you drink that beer out of the keg before cutting it up ;-)
Nice!!
