I am trying to restore a Kundo anniversary clock and need a little help. First of all, the pendulum does not have a regulating wheel like I have seen on most torsion clock, so is this just missing or is it supposed to be this way? Also how do I figure the thickness of the spring I need? Also on the spring guard there is a moveable piece that fits over the pendulum. What is this for . I am trying to learn about these clock, so I appreciate any help.I'm an old dog trying to learn new tricks!! Thanks very much. IMG_2853.jpeg IMG_2851.jpeg IMG_2854.jpeg IMG_2852.jpeg

You are missing an adjustment wheel on the top of the pendulum. And If I'm correct, this is plate #1375 in the Horolovar 400 Day Clock Repair guide, which uses a 0032" (.081mm) spring.

The configuration of the top of the pendulum is for clocks that have a locking plate, which yours does not have. So, I would say this pendulum, even if it had the rating nut is not the one for your clock. Please excuse the dust. I haven't yet gotten to this clock, but it was the nearest at hand that had the locking plate and proper pendulum.

Perhaps the pendulum was for a battery anniversary clock and is not missing a rating nut, since one is not needed on those clocks. I have a couple with brass pendulums before they went to plastic.

It has a plastic bottom block also. It's probably a spring that was robbed from a battery clock.

Thanks for your reply, but would the pendulum fit so nicely into the ring on the spring guard if this was not the correct pendulum. Is it possible that the locking plate is missing and ,thus, this pendulum is correct; appreciate your help. IMG_2857.jpeg IMG_2855.jpeg

Thank you very much. Is it possible for you to post a picture of the back of your clock so I can see how the spring fits onto the pendulum. Also does the spring guard have a ring /lock that the pendulum fits into. A picture would be great.Thanks again.

Without a rating wheel, you would not be able to rate the clock. From what I can see, your pendulum never had one. If yours was simply missing the wheel, we would see a threaded rod under the hook. Almost all configurations of the hook will fit under the spring guard. Your clock looks like a standard Kundo. The pendulum for the standard frequently comes up for sale. If the moderator would move this post to the 400 day forum, you will get more opinions and advice on your clock from many experts.

Thank you again. Yes the hook screws off and the rod is threaded under the hook! So maybe the rating wheel is just missing. I will try to post on the 400 day forum for parts. Appreciate your help.

I have one early kundo with the same style spring guard and pendulum retainer. Looks like your missing the odd little hat shaped lower suspension spring block that fits perfectly into the retainer loop. Your pendulum has the configuration of the modern pendulum retainer and seems to be configured as a fixed pendulum.

Thanks so much .This is very helpful. I am starting to believe this pendulum is not the one that belongs to this clock. I appreciate everyone's help and patience with all of my questions. I might just look for a replacement pendulum and lower block that is correct.

I truly believe the pendulum you have is for a battery anniversary clock. I think you are on the right track to look for a proper pendulum and lower block.

Hello, I just fixed the spring on my Anniversary clock and it looks just like yours. It is .032". I had to buy the book for 400 Day Anniversary clock repair, compared the back plate and they have a diagram to match the length of the spring and detailed info on the repair of the clock. I am not sure if I am allowed to post the name of the book here. Anyways, here are pictures of mine:

Is the book green? See what the ridiculous policies on this board create? LOL.

Nothing wrong with mentioning the books helpful to the repair of these clock. I believe the book in question is the 400-Day Repair Guide by Charles Terwilliger. The latest addition is the 10th. It contains to-scale drawings of most back plates as well has layouts of the suspension springs. It also shows examples of pendulums used...it's not complete, though. Section 7.0 of the guide has an in depth discussion of how the dead beat escapement works.
