[HELP] Concentric Turning To A Bore

I would face the stock to length and drill and ream the 17mm hole. Then I would chuck a piece of stock and turn a stub arbor with a shoulder with a snug fit in the the reamed hole. Then you can slip the part on the stub arbor, center drill the opposite end and support it with a center to finish the O.D. This way there is no indicating to be done and the I.D. and O.D. will be perfectly concentric.

This is exactly the way I envisioned doing it, to the letter. I just wanted to make sure I wasn't over engineering the process so I thought I'd get some ideas from you guys.
