I’ve built many of Clayton’s clocks over the years, and I highly recommend them. The plans and instructions are clear and Clayton is very generous with his advice. His “Genesis” or “Simplicity” designs are a great place to start. I would also highly recommend his “Practical Guide” book before starting your project. After digesting that, and building one or two clocks, you’ll be ready to strike out with your own unique design. The last two clocks I built were on a CNC machine, and worked out OK, but the Onefinity should give a much higher level of precision, which is why I bought one. I’m currently starting a modified version of Clayton’s “Marble Strike”, which should be a worthy challenge. If you decide to go ahead, feel free to reach out, I’ll be more than happy to help.
