My TT 5.4 2V build thread

I don't want to weld to the midplate, and I dont want to go with 3/8 alum (too expensive) since I am bolting it to the midplate with a gasket. This is why I am going with mild steel.

Your not gonna need that much. I would use a planed piece of 1/4 6061-t6 for the base and .093" 6061-t6. Anneal it correctly and tig it will hold immense amount of pressure. Then have it chemically dipped in ceramic which would completely sheild it from temps.
