I would like to build a clock where the face rotates. Imagine a standard clock, but instead of hands pointing to the hour, there would be a rotating face plate with a small window, as it were. The face plate would obscure everything except the current hour, which would be visible through the window. If it makes any difference, I need it to be a 24-hour, not a 12-hour, clock.
I have considered buying a 24-hour high-torque clock movement (because I'm not interested in building the actual gears, etc.), but I get the impression that it would be hard to attach anything to it other than standardized clock hands. I could try to glue the face plate onto the hour hand, but I don't know if that would hold effectively.
Thank you. (Also, if this isn't the right forum, please send me in the right direction.)
