..some small part goes SPRroooooiing and you wait for the tiniest sound of it hitting the floor (or wall, or ceiling) to try and narrow your hunt in that direction.
I knew better.
Disassembling a SK ratchet, I had not been in there before and there is a small pin (spring loaded of course) just WAITING to be released from its prison. It pressures the reversing mechanism to toggle. How was I to know it was in there? Well, it launched (I heard it), but didn't hear the resulting landing Dang! I saw it left a tiny greasy spot on my shirt that in my mind reassured me it had lost some momentum and might be on my left side.
15 minutes of searching, I was about to give up. I had painstaking gone through the trash bin which was nearby. Nope. I started moving equipment (I knew better than that)..nope. 30 more minutes of flashlight aided, magnet assisted searching....nada.
Taking a quick water break, I resumed the search. Right as I was walking up to the work bench I looked down.
Bingo!
Just goes to show, if you work with small parts.......please....try and keep them contained!
