Re: IBM Factory Clock
Hey David, you've out-guessed me, as I've been in touch with the owner, and am hoping that he's got contacts at the old redundant factory(CP- Consolidated Pneumatic). The original main office block is divided up between the local water board & an engineering business. The same business also has taken over some of the huge workshops for storage, other sheds have been taken over by wee local businesses.
Mike T's link might do for someone with 21st century micro-processor/logic skills. Me - I'm just an old analogue fart. I do have some old SW mains powered timeclocks somewhere, but very much doubt if the gearing is in any way compatible.
The wee switch is a cam/lever driven SP/2 way. The rear cam moves the centre contact down for minutes 7 to 60, and the front cam moves it up for minutes 1 to 6. Shall delve further. I still need advice on safely removing the hands, please. They seem to be secured by 6BA sized knurled(non-hexagonal) nuts. And the main securing nut seems to be 0BA sized.
Regards, David
