We used to melt down coke cans and aluminium from old cars in a home made furnace which was basically a smelting pot, a few ring burners and a stainless collar to trap in some of the heat. We cut the moulds out of polystyrene (with a hot wire), then pack them with sand and then poured in the liquid aluminium.
Bit rough but would work ok. Easy to clean up with sand paper. Be carefull not to drop liquid metal onto concrete as the concrete can pop and explode.
- sorry, I meant clean up the edges with a bastard not sand paper, you know what I mean.slappy
