my first furnace was from Foundry101.com and has worked well for 6 years now, Great little furnace for aluminum and bronze. If anyone needs info on metal casting I can get any info you need, my boss at the foundry is a wealth of casting knowledge.
I know of a spin casting machine for sale if anyone is still looking for one, they just want it gone, someone could get a good deal on it but shipping may be pricey its a big unit. I can get more info if someone is interested, id grab it myself but I have no room to put it :(. Ill be getting back to my halftrack build soon so watch for updates on that, the tracks will be lost wax cast in aluminum so ill make sure to take lost of pics.
