As someone who started their journey with aluminum cans and a very diy setup I'd actually argue that it might be better for someone getting into the hobby from a matter of feeling the power of metal casting and getting the passion to continue with it. Starting them off with super simple patterns that you can still make from cans and then after they've had their fun with the cans they move up to the actual good stuff. Taking this approach myself its given me lots of perspective on just how good this metal is and made me feel super passionate about the craft in the early stages. It also just kinda feels like the "Hello World" of the metal casting community haha. Obviously results are going to be worse due to worse metal, but seeing that they can melt an everyday object and reform it just lights a fire I love seeing in peoples eyes.

Note that in an AC circuit, resistance is only one form of impedance at play. A coil of wire also has inductive reactance that further restricts the amount of current. The only way to really check wattage is to measure current flow through the system. As an example, do your math on an old incandescent light bulb.
@DerekWoolverton4 ай бұрын
A heating element is going to have almost no reactance, I would guess less than 1%.

At our families foundry we cast aluminum in a 200lbs and 400lbs capacity furnaces daily. Seeing those ingots and you saying there to big is crazy in my eyes. Not hating or nothing man! Your doing some good stuff! I was just laughing about the ingot size. Ours are 30lbs and 3 foot long. Lol Great job man loving the videos!

Nothing wrong with making castings from extruded aluminum. That's what i use most of the time. Window and door frames are 6061-t6. I turn them into ingots for storage and before casting. All the aluminum, brass and bronze i got was free. I just put the word out i wanted any scrap, now i have about 300lbs of those alloys. Probably more than I'll ever use. All metals are cast at some point in their manufacturing process. Just use an alloy that suits your needs. The electric furnace sounds good. But it's a little hard to use offgrid.

Extruded aluminum vs aluminum cans...to get clean aluminum from aluminum cans, you end up scooping off more dross than actual aluminum...like ALOT of it...a fluffy foamy looking crud...end up using like 20-30 cans to get 1 lb of aluminum. Not sure the small little kiln would even hold cans unless you smashed the bejesus out out of them..maybe one of those larger 8lb ones in a propane kiln maybe.
@adamdewolfe4 ай бұрын
@@haydenc2742 Would be pretty simple to make cans fit in smaller crucible, but would require more processing. Just cut the top and bottom off, cut the aluminum cylinder in half, and roll it up. Presumably, all while wearing gloves. May even be able to melt off the plastic coating on the inside before melting at that point, too.

zinc poisoning (or zinc fever) is by the way completely harmless, sure, uncomfortable, but you wont die and it wont damage anything in the long run. also you would need to weld like a LOT of galvanized steel in a day for you to get sick.
