Question about chimes

I have started working on a Bentima Westminster chime mantel clock. My query is about the chimes, rather than the actual mechanism. The low note (there are four altogether) is completely out of tune compared to the others, much sharper (by a few tones) than it ought to be. I am guessing it has been replaced at some point. How I go about getting one that is in tune with the others? Should I try to find one on Ebay or should I get a complete set and change them all?20230702_131822.thumb.jpg.246848f1a03f23b0b3550db9ef966937.jpg20230702_131857.thumb.jpg.23f56dc6c2f92f194b4075439baab097.jpg

Are you sure it is the chiming rods and not the hammers. Are the hammers playing in the correct sequence? Looking at you photo of the rods they look about right.

The hammer sequence looks OK so I don't think Eric Morecambe is in there (all the right notes but...!). Have tapped the chimes in descending order and they play rather like E D C B-flat (not G as it should be).

Are the hammers leather or plastic. Leather can get hard if leather then brush oil on them, it will take time to soften them up. I suggest trying before replacing the rods. If you need to replace buy a complete set as they will already be in tone. All good clock materiel suppliers will have them in stock.

Thanks. I'll try to soften the leather.

Had a look at the rods and now I can see why the long one is out. It has snapped and been repaired with solder at some point in its life. You can just about see in the photo (top rod).  The other rods have no trace of solder. This will have had the effect of dampening the sound of that rod. Have seen a replacement set (used) on Ebay with the same dimensions for £7.99 so will get those.20230704_202848.thumb.jpg.9449c7aa29d744f0dc22bad54dd0ecbd.jpg

      My profile photo is age 20, last century, but I still look exactly the same so I'm not sure it counts ¯\_(ツ)_/¯

      Lathe motor advice

      By JseTay · Posted

      I sure appreciate your comment! I will look into one of those or maybe something similar. I of course will check your video to have a better idea.  by the way, that’s a beautiful lathe! Mine is a little peersless, but I just bought a Boley & Leinen that is on its way. That’s the one I am looking a motor for. It comes with a motor, but I want to replace it for  one that has a speed controller.

      A lathe with indexing that won't break the bank?

      Indeed. I would not attempt one. Here is my messy Sherline setup

      Hello everyone my name is Tom and I and I am new to the forum and new to the hobby. I have always had an interest in mechanical watches and finally decided to pursue it. I’m going thru online trading and have purchased the basic tools to set up a work area. I’m really looking forward to learning and thank you in advance for all of your knowledge!

      Etachron regulation system

      By JohnR725 · Posted

      This conversation is becoming a very confusing. The etachron system is a very nice system for manufacturing watches. As you know it consists of two components the stud and the regulator pins. Beautiful thing of this system is you can open up your regulator pins center the hairspring and as you close the pins they will close equally on both sides providing you centered it in the first place. It's not like you're going to become closer to one side or the other as the definition of the regulator pins is a bit confusing it's not exactly a slot sort of. I'm thinking maybe a little eight reading will be helpful for you. Then the file name was changed by me at the US patent but the wording of Seiko may or may not actually be attached to it soared up? I just did that so I can find it in my files. Normally patents are in people's name if they work for a company the company name will be there you'll notice the person lives in Japan which is interesting as the name would imply that this is a Swiss product. Somewhere I think I have the patents for the stud and I believe that is Swiss like a lot of things their Japanese and Swiss and then the Japanese let the Swiss name stand as it seems you more popular in case as you read up on the patents of the regulator pins or pin will see and it should explain exactly how and why it works also why it's important to always close at an open in specific directions because the pins actually have a shaped to them it's very hard to see the shape as it's very tiny.   As a reminder with this system it's mass-produced. I wouldn't be at all surprised if they use cameras and computers to do all of the adjustments.  The meaning of this is that the majority of watches will function as there supposed to and do what they're supposed to do the system will allow us for some minor in tolerance and has more than likely as I said no human hand is ever touched those watches that's the way they left the factory and they work fine.
