I've been working with a charcoal fired Gingery style aluminium foundry for two years and am getting a little tired of the trouble of operating it, the smell, reloading... so I've been thinking about building an electric foundry.
Unlike the charcoal or propane foundries there isn't much information available on the net. I'm mainly wondering what gauge of nichrome wire I should use if I want to be able to reach and hold a decent temperature.
Any tips concerning refractories would also be appreciated. I've used a Silica sand /Fireclay/Portland Cement/Perlite combination which has tended to flake with use. I've heard of a Perlite/Furnace Cement mixture which seems somewhat simpler to prepare.
Thanks Jon
