...Machinists Also say, and (I) had to say this to a few impatient customers at My old job at LFW.
"An Emergency on Your Part, Does NOT constitute a Emergency On Mine!"
I remember one Job I was doing. I was working on 3 Tiny, 90 Degree Stainless Steel Gearboxes, that were going into a Satellite to Extend Solar Panels. So Small You could hold them in Your Hands! This was late in the Evening-Overtime. I was 'Polishing to FIT' 0.5000" Diameter Shafts, back and forth from test fitting to Lathe. multiple times. While the NASA Engineer Stood Over Me Watching, as I Assembled, and Torqued, all 3!! I believe they had to be +- 0.0001" Because they were designed to Handle ALL Extremes of Hot and Cold! and NO Grease!!
As far as I know, that Satellite is Still in the Solar System, Or Farther Out. I was Not Told which One it Was, or even the 'Why' they had Me Working on It. NASA does have their own Machine Shops, I Thought.
I put the Gearboxes in his hands, and the Man turned and Left in a hurry, Satisfied...Not even a Thank You!
