This has been one of the best diversions I've had in a while. With my mechanical puzzles, If I get stuck, I can always take out a screwdriver

!
No screwdrivers here though. One big screwball though! Having made it to the end of the road, I'm still a few letters short, and quite a few puzzles shy of finishing. Maybe I should pray to some of those ancient gods that inspiration will strike. My luck, it will just be Zeus' lightning bolt!
