I say you make a lower out of copper
Ill donate the copper pipe ive been saving
Dad and I made a forge similar to these but quite a bit bigger out of an old 6 gal metal bucket. We made a bunch of ingots at first. Then made various small parts by sand casting them. Sand casted parts can turn out very clean if you do it right.
BTW - we used a muffin tin as an ingot mold just like this guy. Worked well.
I finally have a cool idea for a casting. Not really useful or anything, but cool I think. And it'll be a fun experiment. I'll reveal it when I have a chance to get this thing put together and I find someone with a wood shop I can use to made the mold. Hopefully I can pull this off.
Also, I found graphite crucibles on Amazon and Ebay for only $20-$30. I'd get one of these before trying to cut up an old fire extinguisher. And I plan on building a propane forge instead of the charcoal one - we'll see.
If you're offering to sell or give them to me to cut up and use as a crucible, I do appreciate it, but it would cost me $10 to drive there and back and I don't get up that way very often. I'd rather just buy one for $20 that I don't have to cut, etc., have it delivered to my door and use it right out of the box. Maybe some other flat-lander can use them though.
I'm attempting to build one of these. Had to start again after the first pour didn't turn out very well.
I just need to locate a center pot. I'm thinking of getting some thin wall steel pipe and weld an end on it vs the fire ext. example.

thought I'd try it with a compressed air feed instead of a hair dryer. Just so I can better regulate the amount of air.

Cool! Keep us posted.
