It's a big boy jigsaw puzzle... now THAT is "coming from togetherness"! And some other fun ones... I get to see a lot of stuff that went terribly wrong - get called when normal goes out the window

Heck - I don't even like doing the overspeed shut down trips for the USCG when they won't let us downwardly adjust the trip speed or just trigger the relay to prove the shut down works - something about manually forcing a freshly rebuilt machine to overspeed hurts the soul... I didn't get the...
