Bill,
That's aluminum, correct?
Thanks,
Ed

Yes Ed, 7075.

OK -- Almost ready for the mill. The centering of the rear crankcase to the rotary table is being done here. This can become a real PITA. When that happens, the "Golden Rule" should take care of it. That is WALK AWAY.

Did the set-up work, you tell me. 9 flats on the rear case, start to finish.

Looking good!
Bill, any particular reason you used 7075 as opposed to 6061?
I have 6061 on hand for my Edwards Five.

Because of the size of this beast (16+ HP/9500 RPM) 6061 was not considered strong enough. It will do for yours.
