well my one piece tank didnt come out of the shell clean. there was hydrogen in the aluminum from not degassing enough or something. i guess if you want something done right you have to do it twice. frustrating when you do everything right and something stupid like this happens. i didnt take many pictures of the one piece cause i was pretty dissapointed. the other side to my 2 piece barely made it. there was a lot of porosity in the gating but the carved parts survived. looks like i will get 2 or 3 tanks out of this i hope.
