Pallet fallen out

Hi I am trying to get an old russian vostok clock working. The escapement was not engaging and the clock just free wheeled until the spring ran out of energy. When I disassembled it the pallets were rotated 45 an 60  degrees up from the plane of the gear. I was able to return one to true but the other popped out. Just had a frustrating hour trying to replace the pallet. Is there a trick or is it a fools errand??? They seem to be  a push fit

The pallet stone needs to be re-seated. You need to clean the stone of everything that is on it, this includes the part of the pallets that the stone fits in. This is not a job for someone that has little or no experience. Watch/clockmakers shellac should be used to set the stone. It has to be the correct angle, this includes depth and height. Do not use any of the quick hardening glues that are available as they act so fast you will not be able to adjust the stone. If you intend to undertake this work I can list the tools you will need.

Thanks guys. I think that means the job is beyond me. I'm sure after much swearing I could get it randomly sited but couldn't hope to achieve the precision required. Is there any resource to buy a new part. There is a whole new escapement on ebay for $70

With this platform you need to find out if it will fit to engage the teeth of the wheel see photo and arrow, this part must be clear from the wheel it is to engage, you also need to find the leaf count, in other words it must have the same amount of teeth as the original.

      Next is to drill the screwhole this then provides an anchor point so the bridge doesnt slip around while scribing the shape. A cork lid, a pin and a piece of gaffer tape ( 😅 ) keeps it all in place. The hole is measured from the broken part using a hand measuring gauge. Mark the hole, punch it and drill it off to size. The awkward bit is working out where the jumper should be and the detent positions.  I remember watching a youtuber a while back do this with dividers, so i dug out my old school compasses and improvised a little. This bridge only has one hole and to find the detent positions you need two points of reference, so i just worked the second point from one of the corners, hopefully its near enough. Then scribe in the jumper using the two detent positions ( wind and time set ) that were marked and a big picture of the complete spring to look at that helps to give you a feel of where the jumper should be.

      Right now I'm making do with a similar micrometer (the one below is $45 shipped but you can find better deals) and a $20 stand. You do have to be excruciatingly careful measuring jewels, since there's no table, but if you don't have the $500 to throw around, it's a nice option.

      As  I kid, I'd watch Godzilla stomping over buildings and cars and I'd think to myself: Tokyo is a really dangerous place to live... . Cool watch!!

      Next one up an AS 554, looks like a bit more to this one. First job is to check thickness, most springs are somewhere between .3 and .4, this one measures .35, that matches in with the .4 spring steel i ordered. So for marking up a permanent marker comes in handy to colour up the steel to be marked later with a scriber once its dry. Bestfit provide the extra bit of info for the jumper spring that is missing.

      Seitz Tool - Help determine if Seitz or not

      Thanks again, Marc.  Super helpful. I was wondering what the hole was for, and now it makes perfect sense. With your help and the other members here, it looks like I'm good to go with my Seitz tool set. I had to order some replacement pushers, but with those, the set is complete and in good condition. Now, I need to figure out what tool to buy to measure jewels (amongst other watch-related parts). I had my eye on the JKA Feintaster micrometers, but people get crazy bidding on them for $400-600 USD. I was thinking of just a regular digital micrometer (Mitutoyo). Thoughts?  Mahalo. Frank
