Here is a problem I have run into, but it may be outside the scope of your project.
I am not a Horologist. In fact, I am more like a clock undertaker. However, I do try to see why a clock is not working before I disassemble it. Cuckoo clocks and small clocks that use a pendulum to control the speed at which a weight (or spring) moves have to be attached to a solid wall to work correctly. Otherwise the motion of the pendulum causes the clock to also swing and nothing works right. Wall space is a treasured commodity in my work area and is taken up with shelves and cabinets. Also, it is hard to work on a clock when it is against a wall.
What would be useful is some kind of stand that these clocks could be mounted to while working on them. Solid enough to hold a clock stable, but small enough to be stored away – perhaps some disassembly. There would need to be space for the weights and pendulum to move or swing freely. Check out a black forest cuckoo clock for the right scale.
These things may exist, but as I noted, I am not in the professional clock repair business and have little familiarity with what is available.
