Hi,

I’m working on a simple pocket watch movement and am having a very hard time getting the impulse jewel into the pallet cock fork and then getting the pivots into the jewels and every thing staying in place, especially the impulse jewel. 
I’ve performed this several times on other watches, but this one is just being a pain ( not that they all weren’t a pain). 
Im a novice and would appreciate any tips, tricks you guys use to make this more simple. 
Thanks much,

Bill. 
the below photo is before I installed the pallet cock.

Hi What I doand hav little trouble is to align the fork to the out stde edge of the watch pick up the balance on the dangle and slip it in to the fork and then lower into the lower jewel, usually works but not always, just takes a steady hand and patience. I suppose we all have our own way of doing it.

 Depending on the movement, you might instal just the train gears and its bridge first, you would have access to gears from both sides of the bridge, next test the train and if its alright proceed with putting in the barrel  and its bridge then. Sometimes you might need to loosen the screws to the train bridge a bit to slide the barrel in.

You do not need to fit the balance with the impulse jewel between the horns on the pallet fork. I don't know anyone who does that.

Try setting the fork to one side or the other. Then bring the balance into position and drop the lower pivot into place, but rotated 90 degrees, so the impulse jewel is well outside the fork, in the direction you set it. Now carefully rotate the cock into position and get the upper pivot into it's hole.

    • Well, my fundamental stance is that I want to go in and out without leaving any trace other than a shining, perfectly running movement. So, no scratchings on the inside of the case back lid, no marred screws, no debris, no fingerprints, and so on. That is, my goal is to make it impossible for the FBI to track me down. As a professional, I suppose you might want to keep track of returning watches, but as @JohnR725 mentioned, we can keep detailed computer records without marking the watch at all. That may not be true for every watch, but luxury and COSC-certified movements do have unique numbers. John also says it’s best to leave no sign you were ever there, and I couldn't agree more. Now, suppose the Sea-Dweller I'm working on is one day scrapped, and you want to sell the case-back separately (perhaps the case was destroyed in a plane crash). Then the scribbles on the inside no longer reflect the current movement inside the case. Also, the engraving will likely halve the market value of the case back. It had been "sleeping" for about a week and a half. Yes, the "debris/old lubricant" theory is my hypothesis as well! It will be interesting to see what I find once I have time to start disassembling the movement.
    • I've repaired a few of these, having some success with stripping and cleaning the mechanism.  They are so cheap though, its hardly worth the effort in many cases.
    • Get well soon Old Hippy, torn muscles.,  not good
    • Id love to see how he has the output shaft mounted to this setup, as I have the same rotary stage and stepper in my build.
    • If you see at least one thread protruding, or even a half, then you may have a chance using this "tool", but don't squeeze hard. Lot's of patience, and if you notice any signs of loctite or other adhesives, then apply several drops of acetone on top of broken stem. Use heat (hair dryer) also. You should be able gradually turn it counterclockwise, just like i did on this broken Timex stem, which was glued with something like nail hardener. Then you can use an extender to save your broken stem. https://m.media-amazon.com/images/I/513DVvkfW5L.__AC_SX300_SY300_QL70_ML2_.jpg   You can also try cutting a small grove / slot on top of the broken stem to use 0.7mm flat screwdriver.   Depending on the Crown material and Stem material, you can try dissolving the stem.
