Brandy, 

What's a "mike" job on an exhaust nozzle consist of?  Measuring the opening?

Just a bit more than that. The exit chamfer mist also be cleaned up/trued, if worn/damaged from steam cutting. Without that very critical chamfer, the exhaust blast will not properly match the inside taper of the pettycoat pipe and stack ID, which is how the vacuum is created within the smoke box.

Great answer "Hot Water", The old master machinist that took me to the L&N Shops, showed me how they did the machine work on exhaust nozzles, as there was one sitting/standing vertical on what I remember was a "BridgePort"  milling machine. I remember there was at least a dozen nozzles sitting around the immediate area of that big machine.

They traded that area of the old Louisville Roundhouses & erecting Shops for a Papa John's Football Stadium.

Thousands of jobs gone to the age's, man what a shame!.....................................

Thanks for the answers, HW and Brandy.  I have a question about stack sealing from the exhaust nozzle that I will post in a separate thread.

By the way, I live in Louisville and grew up here.  In 1980, my Dad took me to the L&N South Louisville Shops 75th Anniversary open house and we got to see the back shop, transfer table, etc.  Unfortunately I was only 9 at the time and didn't absorb it all like I would today but it was still a neat experience.  As Brandy says, the then-closed shops were demolished in the mid 1990's and replaced by the University of Louisville football stadium (where we attend games every fall).  As an homage to the origins of the site, the stadium has a diesel horn that they blow every time the Cardinals score!

My uncle was an engineer for the Chesapeake & Ohio and home was Russell, Kentucky. Before he pasted away, I tried to take him to the 2716 when it returned to the Kentucky railway museum, but he was not well enough to make the journey. I really enjoyed listening to his adventures behind the throttle of many locomotives. He was proud to be a steam engineer and the 2716 was one of many locomotives he operated.

I now live in Lexington and wonder where the restoration will happen. I can't help but be a little skeptical of this project. My heart hopes the 2716 will see the rails by 2020, but before I financial support this project, I need more information.

Does anyone know the credentials of this organization?
