Completely forgot about this thread till I tried to sign up here again.
I doubt any of you care any more, but the project was a failure. I could never make a turbine that spooled how I wanted it that was also durable enough to use in the heat of exhaust. I sold the CNC a couple months ago and chucked everything in the trash.
It most likely would have worked If I had access to machines that would have allowed me to cut titanium, but I doubt I'm ever going to find out.
thanks for the kind words guys.
