I was fortunate to be on a Repair ship, USS Cape Cod AD-43 stationed in San Diego California. Our machine shop was very well equipped, 20 lathes from a small threading Hardinge to 2 VERY large lathes with 6 foot chucks, We also had 2 VTL's, Vertical Turret Lathes, with 8 foot OD chucks, 1 Horizontal Boring Mill, 8 Knee mills, our own grinding shop with a cylindrical grinder that could grind a 6 foot pump shaft, taper grinding as well, and even had our own plating shop. And the tool crib was to die for, oh those were the days...LOL We spent 4 months in Yokuska Japan repairing ported ships., big project was to replace ALL the Fuel transfer valves within the USS Midway. If memory serves there were 42 of them? We had our own mold shop that cast the valve bodies and our machine shop we machined valves, stems caps, nuts and hand wheels. We machined the valve bodies, then ground them so then the Machinist Mates,
(valve guru's) would lap the valves to ensure a good seal. I have a picture somewhere of the last one going out the "Sally Doors" to end the project.
Workday's were 12 hours for 3 days, then one 24 hour shift, then back to 12 hours for 3 day, and continue this for 4 months straight, no days off.. oh and to add more fun, when our ship connected to shore power, it failed to supply us with enough electricity to run so we were forced to run our power plant, read boiler plant for four months. It averaged 120 degrees in the shop 24 hours a day, 7 days a week...Builds character ya know...LOL
