    I was able to complete this clock and am extremely happy with the design. I never thought I hand made wooden clock could be accurate, but it's much better than I though. I tracked it for about 3 hrs with a stopwatch and it was easily within 30 seconds.

    Thanks to Rolf for his support via email and kudos to Alfred who I believe generated the original design. Overall, this is a wonderful design.

    I'm not sure what the maximum posting size is, but I've attached a couple of photos so hopefully they make it through. I was primarily interested in how to build this clock and make it work, so I didn't do a thorough job of sanding/finishing. That said, I've purchased 3 more circuit/coil sets from Carveshop and plan on building them as gifts.

      I don’t see any pictures. After you uploaded did you click on the done button in the upper corner? I forget that step and they won’t post.

        These are Charles's pictures that he was kind enough to send me. The clock really came out great.

          I just recently started on this clock and I know this is an old post, but if you can help I would appreciate it.

          The problem and the place I am stuck is the tri excentric (J). Looking at the plans and your PDF drawing on this forum I am really confused as to how this works. I see that the plans call for the tri excentric (J) to be 3/8” diameter but part G, S and K have a 9mm diameter hole. My question is upon looking at the assembly drawings, does part J fit into G, S and K? I don’t see how they can because 3/8” is a bigger diameter than 9mm.

          Am I missing something to how the tri rotates around the daisy?

          Thanks in advance.
          Rolf I am having the same problem. Could you possibly send me the solution as well. Would very much appreciate it

            Can someone with experience on the electromagnetic gear clock help me understand the working of the tri and daisy. I can't seem to get this. It seems that the tri pins are too close for it to rotate on the daisy. Any help would be appreciated greatly.

              Grandad I will send you a private message with my E-mail. It will be easier for me to get the information to you.
              The TRI is a bit of an odd device. Some of the files I want to send will not work on his platform.
