The movement design is quite straightforward and is time only with a regulator style
dial. The hours appear in an aperture in the dial. The dial itself is a solid piece
of etched silver with the numerals filled with enamel. The hands are impulsed once
a second by means of a solenoid arrangement acting on a ‘scape wheel and activated
by one of the mercury relays as the pendulum passes the center point of its excursion.
The solenoid draws less than .1 amp and is an insignificant load on the relay, well
within the operating specs. The movement has been running for almost 7 years now
with no problems whatsoever. I used C-
When I built Q1, my shop wasn’t particularly well equipped and the project was somewhat ambitious. I had only a Myford Lathe and a small Clausing Mill as well as the usual hand tools. Because of that, a number of the machining processes were quite challenging. Because I enjoyed designing and building this clock, I decided to enhance my workshop as time and finances permitted. My workshop today is fairly well equipped and sheer enjoyment to work in.

(BELOW RIGHT) An open view of the dial movement. I opted to relieve the gears in an untraditional way. It’s a bit faster and I think a little unusual and attractive.
The regulator dial has an aperture through which the hours are viewed.
