I decided I wanted to create a beginners guide to building an electric gear clock. The last while works very well will be labeled as experienced since it has more moving parts and needs tighter tolerances.

The front and rear plates are simple and need no bushings installed. As long as the arbor holes and motor mount holes are unaltered the front and rear plates can be just about any shape or material. The face has four mounting holes that need to line up with the plate spacers, but other than that it can be altererd in any way.

The motors I plan on using arrived and I was able to build the prototype. After I cut the parts it went togeter in less than an hour and that included rounding over all edges.

The two plates are held together with 1/2" x 1/2" x 2-3/4" pieces of stock. These should probably be the same material as the plates. IE if walnut then these should be walnut.
I used drywall screws on the prototype but these should be nice looking brass or painted screws.
On this design. I just milled pilot holes with the CNC and drilled the diameter needed with the drill press. This worked out better as some of the holes you want the brass parts to fit loose and others tight.
There are 4 places where the brass tubing needs to be glued to the gear or of plate. I had been using a thick CA lue but it does not seem to hold. I need a glue that will stick to brass resonably well. I say resonably becuse it is not as though there is any load. As a matter of fact on this proto type I am not using any glue.
