Mystery Clock

Thanks! In addition to a great conversation piece, it also does keep accurate time, unlike many wood gear clocks. The electronics is truly unique. I've had one running for over a year now on a 5v power supply and I haven't had to adjust the time at all.

The drilling method is explained in the .pdf manual that you can download as Try for no charge. I've found that my machine does not drill very precise diameter holes. The holes must be very precise so that the brass tubing will press fit into the holes. I recently tried drilling a 1/8" hole using the 1/8" cutting bit, and comparing that to a 1/8" hole using my drill bit, both bits in my drill press. The brass tube slips in and out of the cutting bit hole - literally falls out - but is a press fit into the drill bit hole. So that is the reason.

Oh makes sense. I've seen it on other projects and always wondered why. thanks.
