Pretty cool, reminds me of my apprenticeship. Not quite as many lathes or as big as some of those big ones, but big enough that to measure the bore on some of the jobs I had to climb inside the bore with a 1.2m long inside micrometer. How the **** you're supposed to accurately measure with a 1.2m long inside micrometer I have no idea haha.
I only spent my 1st year in the machine shop, after that it was out on the plant, where micrometers were still in their shiny packets, screwdrivers were used as mini pinch bars, and a 12" shifter was a hammer, pinch bar and just about every other type of tool at some stage. I still carry one in my pocket, though these days it's a fancy bahco wide mouth one.
