Purchased a Seitz tool, didn't realize it was missing a part


Recommended Posts

I want to try setting my own jewels, so I purchased a Seitz tool.  I only realized after receiving it that it was missing a part.

Is my research correct in that the metal plunger tube thing with the rounded top that the lever presses against is called the "spindle"?

If so, where can I source a new one of these?  I was able to find someone selling a spindle, but I don't know if these come in different shapes and sizes.

I know it'll need a spring as well, but do you think this would be a compatible replacement for my tool?  If you are uncertain, what should I check on my tool, and what questions should I ask the seller to be sure?

Isn't the hole in the side of the tray only for the spindle for the reaming tool? The mushroom head of the pusher spindle would not fit in there.

I think there are two types of spindle for the pushers.  The newer style has a removable head and can be used with a micrometer attachment.  That tool looks like an old one and would use the once piece spindle, like the spindle in your pictures.  I think both kinds of spindles are the same size anyway, and both use 4mm pushers, and are probably compatible.

Ah yes, that's right.

 

The spindles are 8mm diameter, same as Favorite, Chatons SA, and Horia. Horia is still going and sells the spindles individually; they have both keyed and non-keyed (they call it "furrow"), the Seitz takes a keyed spindle but will work with non-keyed, just back out the locating screw. Horia has the spring too. You have to specify 3mm or 4mm hole, and they have 3 lengths; Seitz is 76mm total length, their longest is 74mm, which should work fine.

Hi everyone. Thanks for the responses. I'm glad to hear that the spindle on ebay could be a suitable replacement.  Since the holidays are coming up, I won't be starting any new projects till after the new year, so I'll try my luck on getting the spindle for cheap on ebay.

    • Welcome to the group Stirky. You can search for just about every subject in the craft here. Don't be afraid to ask if you can't find the answer that may have already been covered ( some ad nauseum LOL ). You don't have to buy Bergeon to get good quality. There are many decent mid-range tools available that will last you a lifetime. Cousins would be a good place to start . Cheers from across the pond ! Randy
    • I picked up a similar amount of these jewels some years ago in a watch and clock fair. Every now and then they come in handy. This week I've got a rubbed in bombe jewel in the balance cock that is cracked and needs replacing. Very handy to have a vintage assortment of these type of jewels!
    • Great diagram with the teeth and pinion count. Simple way to reduce the speed of the hour wheel by the 12:1 minute wheel. Genius and yet so simple. Always good to reinforce the principal by what you have done in your drawing. Keep doing that. I had a drawing on my wall for years showing me this which is very similar to the drawing you have done. Here's a formula to work out the beats per hour of a watch movement. The movement's BPH is dictated by the wheel teeth and pinion count and the hairspring being vibrated to the correct BPH by finding the pinning up point on the hairspring using a vibrating tool.  The reason in the formula there is X2 on the top line is because there are two pallet stones.
    • So I just wanted to say "thank you" again.  The angle is the key bit it seems and yes, it did basically just fall, or float, back into position when I got it lined up just right. I had meant to add that now that I see how it goes in, I totally see how it came out in the first place, and that whomever cloned the original movement didn't pay much attention to the fine details around the setting or how it interfaces with the balance cock or the "rings" on the regulator and/or stud carrier arms.
