I got curious that Maurice Gavin’s seems to be the only design of clockwork drive available on the net and decided to dig around in old copies of the BAA journal (both digitised and paper!).In 1974, vol 84, no 3 (April) page 189 D. G. Daniels describes a similar device looking a bit more like the one I built (long since gone to the scrapbox in the sky). If you’ve got a fast connection you can download a copy from the BAA (6.57Mb) a real blast from the past. If you do then rather than spend hours trying to scroll to the right issue do a search for time-switch (the "-" IS important!).Roy
