Great videos and Ideas, and I see you have plenty of use for the material And would love too see someone casting Iron using a waste oil furnace HA! awesome!
I have a Vid of a burner that produces that exact type of flame and in the downward fireing aspect. As you can see in the vid, I melted a copper 1" pipe with the thing in open air pretty quick and it wasn't even running that hard. If you look for the vid on my channel called "Waste Oil Burner Downwards firing for scrapping" You'll see it. Not sure If I can link vids yet or the spam filter still thinks I'm suspect.
I preheat the thing on gas to get the internals warm and then just change over to oil. You can see by the flame size and colour when it's running on oil and the gas can be shut off. Dosne't take long to get it up to speed and it will run all day on whatever free oil you want to throw into it.
This is a handy burner and I have been meaning to make another vid of it. I also have another higher output one in the works I want to build because I though it would be good to have a downward fireing one for the scrapping furnace.
I thought about how to do this given the one in the vid was built at least 5 years ago and how my now considerably increased experience could improve the design. I didn't come up with anything. The design is spot on and really, is only a slight modification to my other burners that work so well to allow it to fire downwards instead of up or horozontally.
Cool, Looks like I can link vids now. That's a help!
Casting Iron is a goal. I have no doubt or worry I can do it easy. The thing I do have to work on is a furnace that can stand the heat I'll throw at it to do this. I can melt copper with ease and the melting temp of that is close to cast and heat output is something I think I have pretty well covered. The last real furnace I tried I melted the stainless I had lining the bottom of the thing and went through the proper insulation tiles I had like it was foam. Got all that in a vid as well.
Once I get some proper refractory happening and a crucible, I'm looking forward to going to the holy grail of cast and give steel a crack as well.
