Oil fired crucible furnace

Maybe I can create an outside snow free space nearby, along with re-organizing my workshop. I also do wonder what the cold will do to my ability to reach iron melting temps. It will probably require pre-heating of the blast. I have done aluminum before in winter with a simple charcoal furnace, so I'm sure that at least is possible.

I doubt that the 40°C difference in temperature is going to make a lot of difference in comparison with the temperature needed to melt and pour cast iron!
Good luck! Regards, Matthew

Vtsteam,
I have read your casting posts several times.
Any more progress?
I use to carve profiles of my grandchildren in wood
and have them cast in brass, 9" x 9" x 3/4".
I want to do several more of these but the foundry
I dealt with has long closed.
I would like to cast my own carvings.
Just getting started.

Hi unclesteve. I haven't cast since I last wrote here -- I started on a major moving and cleanup of my "shop". It's now in fairly good shape. I have moved my furnace down the hill to be near the shop, and have kinda been entertaining the idea of trapping heat from it to heat the shop. Not too attached to that idea, but still holding it as a possibility.
Meanwhile have been cutting trees and splitting wood to prepare for winter. Also been building a small foam RC airplane in the evenings.
I'm sure you can build a furnace to melt brass, and would be happy to help if I can. Brass melts at a lower temperature than iron, so a furnace and fuel requirements are easier. I've melted brass with store bought charcoal briquets in a regular Gingery charcoal furnace. Of course you can use any other fuel as well.
Brass does present its own problems -- overheating burns the zinc in it -- and there are some casting differences -- but these are all pretty well covered in the available info. Temperature control is important.
But I think it is very do-able, if you are interested.

Vtsteam,
Have you seen this burner?
Comments.

I just made this burner.
I used 2" outer tube.
I used 1/4" pipe for the oil feed with a
cap drilled similar to a shower head.
Tested it with water, works great but
I have no experience with oil burners.
I will continue on tomorrow, right now it is
time for a beer. Anyone else like
Budweiser & Clamato?
