That's more than I knew when I asked. Thank You.
For me, I have a couple projects I would like to try in Aluminum, and a couple more in Iron. The last two are the ones I figure will be the most difficult (because it's Iron). I figure I could cast simple Aluminum parts like covers and what not here. I would be hard pressed to generate the heat (BTU's not just degrees) it would take to melt the Iron.
