If you get a chance, would you care to share more information on casting? What kind of furnace do you use? Where do you get your metal from....is it just scrap stuff? How do you make your moulds?
I'm very interested.
The furnace is heavely based on a design in the book "Li'L Bertha" by David J. Gingerly ISBN 0-917914-16-3
Its electricaly heated (no mess).
I just used a different controler and had to adapt the electrics to 220V. The original design was for 110V. (I have a few engenering degrees electronics is one of them)
I work in an aluminium plant. I use what ever is on the scrap heap, sssttt don't tell my boss.
The moulds are either the original parts glued together or repaired with epoxy or wax. I also make wooden molds
From these molds I make a negave in sand (actualy a mixture of sand and oil, I bought in a shop that sels supplies to bronze casting artists).
It takes a lot of patience and sometimes a few tries. I am a specialist in fail casts.
I'll see if I can get some pics on the web.
