    I need a replacement winding arbor for the #1 gear (mainspring shaft everything but the mainspring itself) for a Seth Thomas kitchen shelf movement. The wheel, click and click gear have been completely destroyed. This is a rear mounting movement with a shorter winding shaft so a part from a front mounting mantle or wall clock movement will probably not work because the winding shaft will be too long. This is a traditional American time and strike movement where the time winding arbor turns CCW. Does anyone have a replacement part that will work in my customer's clock??

    Thank you,
    Bob

    If you can post a picture of the movement & the gear needed, perhaps we’ll be able to help

    OK, Jim. Thank you for your reply. I will take the mainspring off the winding arbor and try to post a photo here. This is a standard looking American movement from a Seth Thomas clock and I believe most American time and strike movements from the early 20th century look similar, so I thought my request would be obvious. The only difference would be the length of the winding arbor, diameter of the driving bear and number of teeth in the gear which I would establish here once I find members with movements from which parts are being pirated. But I will try to post a pic, as requested, if that would help.

    Thank you once again.

    I have attached some photos as requested. I still need the winding arbor and would appreciate hearing from anyone who can help me with the part.

    Bob, thanks for the pictures. I have quite a few of these in my spare parts bin. If you want to provide me with the dimensions you named above, I’ll see what I can come up with. Perhaps the size of the winding square also.

    Jim:

    Thank you for your reply. To be clear, I am hoping to replace that item shown in photo on the left above. Here are the measurements for the winding arbor according to my digital calipers:

    Diameter of the large gear (tip to tip) - 71 mm approx 2.75 in.
    Number of teeth in gear - 84
    Length of winding arbor (front to back) - 55 mm approx. 2.15 in.
    Diameter of winding arbor - 4.5 mm

    The winding arbor takes a #6 American winding key - 3.6 mm

    I think the first three of the above measurements are most important. If you have anything in your spare parts inventory which will replace this part we should have a brief phone conversation. I'd want to insure that click, click spring and click gear are in decent working order. If you'd like, my email is fixer_123@yahoo.com and I would be happy to call you at a mutually convenient time, if that would work for you. Thank you again for your help with this item.

    Happy Thanksgiving!!

    Bob
