Applying air flow giving a forge effect could get a guy to a point where we could smelt with used motor oil.
Using a propane burner currently, do up to 160lbs per melt.
Was considering building a unit to melt up to 300 lbs using wood and/or umo. Have coal also but it's larger chunks.

An old hair dryer should move the right amount of air, add a 2" or 1 1/2" pvc pipe to get it there. You could still swirl with tubing inside the firebox as if you were using a factory made tweer. I would not expect it to last long but cheap is good. SOme interesting reading here. https://books.google.com/books?id=L...EIUjAG#v=onepage&q=coal furnace tweer&f=false

If using oil, you need a copper loop going around the flue to pre-heat the oil, and preferably a pressure pump and orifice to spray the oil into some sort of burner. The only other way I've made it work is just sort of let the oil drip onto a screen or expanded metal grate where it can disperse and burn, but it doesn't put out much heat that way.

Plastic would melt. BUT, got stacks and stacks of 6.2L and 6.5L Chevy poppet DI injectors and scads of decent injection pumps. Stick all 8 in the stove, hang a pulley and a washing machine motor off of the pump, and voila! I wonder if I could make the stove air-tight and run a turbo off the exhaust...

Now your talking. Save the wood I'd have to cut, split, & stack & use something I generate a bunch of without sweating.

I'm actually thinking about putting something together. I only have 2 55 gal drums of used engine oil...

was he trying to make a rocket engine?
I think you'd just have to drill some holes in the bottom of the stove over the top of your ingot molds and shovel the ww's in through the side door and pull the clips out the other side.
flux wouldn't be needed but you'd for sure have to do a remelt to deal with the oxides.

How's that work, looks like pretty good?

It does. I use diesel with kindling to get it going, took maybe 20 minutes to melt a solid 30lb chunk. Then had to thaw the spout/ball valve so it would flow. Very nice to have the bottom pour. More splatters than ladling. Need to neck down pipe to about 1/8", I think that would cut down on splatters.
