Here is another great sight for plans. https://lisaboyer.com/Claytonsite/Claytonsite1.htm. I have done his robot Laboratory plans, and all worked great except one, I emailed back, and we figured out why. He was great to work with and very enthused. and helpful. It was not my problem, but between us, we figured out a needed change. And yes, these clocks and their gears can be cut on a scroll saw. The workers were available. But we advised they are not like normal clocks, and I think most only run for a short time. Like 30 minutes or so. I have cut out one clock and had trouble getting it to run, but it is still on my shelf, and I hope to get back to it sometime. Go for it, it is a challenge. But many have succeeded. To me it would be a success like I felt when I built a hand crank street organ and heard the first clear notes from it, all most as exciting as my children being born! Well not maybe not quite as much as babies being born. But getting there.
