One of my oldest memories is disassembling an old wind-up alarm clock, down to a pile of gears, then trying to put it back together. I got it together, but alas, it never quite worked right...
Oh man.... that brought back memories for me too. When I was a kid, I musta been 8 or so, my dad had a very loud alarm clock - Westclox Big Ben. It had a brass stem on the back for setting time of day, another to set the time the alarm was to ring. And it had two keys, one to wind the mainspring, the other to wind the alarm spring. And... a little slider behind a siding door for +/- on the time of day, and as I recall (maybe) a slider for the loudness of the alarm. Not sure on that, because I may be getting it confused with the one I eventually got, which was a later model.
Anyway... the Big Ben crapped out one day, and my father tried to have a look inside. You had to unscrew the keys from their shafts, and there were a few not overly small screws that held the rear cover on. He couldn't get it to work, put the cover back on and pitched it in the trash. Next day, he had a new one he got from E.J.Korvette or a store like 'em, up in LINY.
So.... I dug down into the old coffee grounds and such, and dragged out the food covered alarm clock, rinsed it in the sink, and snuck it into my room. Similarly, I rummaged a few small screwdrivers and eventually some pliers from dads "workshop" in the basement. I had it apart, down to the last gear, and back together. And... (love it) I found the alarm spring had broken off its shaft, so I just filed a bit to make a new end and bent it like the original.
The damn thing worked perfectly. Ran well. And on Monday morning, I was up for school ... this was 2nd grade, so how old was I?... and dad "discovered" his old alarm clock, free from tuna juice, coffee grounds and mac-n-cheeze leftovers, _and_ working. He beat me silly, yelled and hollered about taking something he threw out and having my way with it, and confiscated the repaired alarm. That was the last I ever saw of it.
Mom got me one, against dad's say-so, for my next birthday, and I kept it till I was married, which was about 40 years ago or so.
Those clocks were a marvel of American crap manufacturing, with "bent tabs" holding the works together inside, and crude stamped from sheet metal gears and such. And even a 2nd grader could fix 'em, that's how simple they were.
Dad was funny about his kid showin' him up, cuz I got that same beating for repairing the dead lawnmower (magneto wire) and wiring on the trailer hitch (bad ground). I think I was 13 for the lawnmower, and 14 for the trailer hitch. He was a real ACE of a carpenter (not by trade) having worked building houses as a teen and young man, and I learned a lot from him on that, but mechanical stuff... wiring... not overly adept I guess.
Anyway, thanks for joggin' that story outta my brain's innards.
