How does one know when there really is a place for you in a particular machine shop...? Lots of gear boxes and pumps are just like this.
When called down to a 5 or 6" boring mill, and a set of those castings are sitting there on a pallet. Not even doweled yet...aside from a long straight bore, it'll have a pair of thrust faces inside with location, spacing and width specs. The bar is usually shop made, with HSS bits and a support bearing. Between set-up, roughing and finishing, that top half might get unbolted and opened 3-5 times. Good times!
Sincerely,
Toolmaker51
...we'll learn more by wandering than searching...
