I dont know if people know this, but magnesium is a very very hard material to deal with. Main reason...It is highly highly highly flammable.
I was talking to the INDY-fab guys when I went to the facctory and he told me the only problem with them making a mag frame is the fact that it is very flammable. Obvioucly welding it would be very hard, almost impossible. (im pretty sure thats what he said as far as the welding goes)
So really, I dont think I want something thats very flammable spinning very quickly under me.
