in the 1990's I used to make clocks from old broadcast tv equipment (tape heads, motors/rotors etc) and old computer hard drives (10", 5.25". 3.5", 2.5" etc) and the like. I used to give them to friends as presents. I found an old photo album with some of the photos of the finished clocks + some of the clock bits. it's a shame I wasn't a better photographer at the time! this was pre-digital camera days so I didn't know the lighting (& framing) until the film was developed. I found one box of clock bits, but not the box of clocks and other clock bits boxes - maybe I can make some more if I find the right boxes.
