OK so let's start with, I'm an idiot. However, I'm a happier idiot than I was 10 minutes ago. Before I get into the whole story, let me deliver on answering the thread title question: Q: How do you find a lost part in your workshop? A: Order a replacement, and you'll find the missing one right away. Works every time. Tonight's example: I was fitting the tuning machine bushings on a kit guitar I am building, and I didn't quite have the placement of one of the holes right so I wanted to tweak it a little with a reamer. The bushing was stuck tight in the hole, so first I had to tap it out from the back with a hammer. I found that I had a soldering iron tip that would be the right shape to push the bushing from the back and I hit it with my hammer. The bushing and tip went flying across the room like a bottle rocket. I soon found the soldering iron tip on the floor over there, but no bushing. (NEXT TIME: WRAP A HANKIE OVER THE HEADSTOCK TO CATCH THE BUSHING! OR PRESS IT OUT WITH A C-CLAMP!) Did I mention I'm an idiot? To say that I went to extraordinary lengths looking for the bushing would be an understatement. I moved furniture, I emptied out boxes that it might have dropped into, I went through the trashcan that was nearby, I threw out a bunch of stuff, I organized stuff, I spent hours looking for the damn bushing. Finally I gave up and ordered a new set of six bushings. A few minutes later I decided to give it one more try. I found the little b*stard in a box full of transistors in between some little mini manila envelopes packed tightly together. Initially I had thought there was no way it could have slipped out of sight in that box and hadn't picked through it completely. I immediately ran downstairs to the computer and cancelled the order for the replacement bushings. (Sometimes this trick doesn't work until the item is already shipped and you're on the hook for the new part, but I got lucky this time.) My workroom is a bit neater than it started out, so there's that. And I found my fret crowning file in the process, so overall I'm ahead of the game. Now I just have to tweak that hole a little and hope the bushing fits a bit better when I'm done.
