He actually let me watch him make it and talked me through what he was doing since it's the first time I went to a machine shop. So I was standing there for about 1 1/2 hours and I got to see him using the manual lathe and I have to say it's pretty cool getting to see the guy get a solid piece of 2025 aluminum that he got from a scrap metal bin and turn it into the hub. So I can now get some more work done on the motor like taking the muffler to a welding shop so someone could weld in the outlet tubes.
I took a photo of the finished hub.

Good job - congrats. But, you could have the machinist add some flats on the smaller shank so you can use a wrench to tighten it on. It would be a shame to use vise-grips on that nice surface.
Also some knurling added to the prop surface face will help keep the prop from slipping. Just practical hints offered in great sincerity.
Sincerely,
Richard
