Pallet cock

Question

Hi

I have just started my first rebuild.

I'm hoping to get help.

I'm doing my first rebuild and i've come to the escape wheel and the pallet (the anchor thing with 2 jewels that interacts with escape wheel)

Do they just have to be placed on the jewel? I can see no hole within the jewel to accept the escape wheel or pallet.

It just seems very loose.

Is this correct or have i made another mistake

Thought i would ask before screwing down the pallet cock.

cheers

Huh... Very odd that a pivot jewel would have no hole for the pivot. Can you provide a picture of the situation? Could it be a capped jewel but with hole jewel missing?

I think i've explained wrong,There's a hole with a jewel at the bottom of each hole.The pallet  and escape wheel both fit in the hole. but there no hole, In the jewel itself? So the escape wheel and pallet are loose fitting into there holes.

God i hope i've explained that better

apologies

Have you looked at any YT vids of how a watch works? Sorry I don't have a link handy but there are a bunch, some of tge old ones from Hamilton and Elgin/ Waltham are superb, very clearly showing the function of each part with animation and everything.

If you can't see the hole you are not using a loupe. 

Then if you see the hole, but the wheel or pallet fork fits loosely as in never finding its place , then the pivot has been snapped.

See the two purple hole? the jewel holes? The escape wheel axle or arbour goes in to 1 hole. and pallet? or fork? axle arbour goes in other.?

The teeth intermesh escape moves fork or pallet which then in turn moves balance..

But both escape and fork are loose.

If what I am seeing is what I think I am seeing, I can see a hole for the pallet fork with an intact jewel. Again, it appears to me that the jewel for the escape wheel is absent without leave.  I do hope I am wrong for your sake.

Huh that would make it a very unusually shaped pallet. Can you photograph that part for us too?

Yes. But the pallets would line up with the view holes in green and I can't see anywhere else the escape wheel would go.

That's why I think the escape jewel is missing.  It should be in the hole circled by the left green circle.

Then I see no obvious place for the escape wheel in the plate.

The beauty with escapements is the fact there has been so many different solutions throughout time, take for example the escapement in a pin-lever, sometimes you have them setup like a super duper co-axial speed racer.
So in this case one really can't tell what it is or how it is configured until he posts Pictures of the complete movement, before strip  or at least Pictures of the escape Wheel and fork.

    • Some updates, I measured the  mainspring barrel of a 6498 and it's 16mm. I also tried loading a 10mm mainspring on an undersized winder, it did not load fully. So I answered my own question hehe. thanks.
    • Thanks. A small correction to my earlier post,  it is a Poljot 2614.2H, not a Vostok. http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&&2uswk&Poljot_2614_2H
    • I've been thinking about getting a Russian watch myself. Nice piece Andy.
    • This is the progress so far. The first image is the ebay seller's pic and the description was "Does not start, maybe battery but unable to confirm". In reality, it wouldn't wind, wouldn't set and the scratched up crystal looked even worse in real life (and the second hand had fallen off in the post), but I figured it had to be the twin of the one I already had, and therefore was well worth the 0.99p I bid.
    • Thanks for the correction regarding the movement. You are spot on  with the fiddly calendar works, the first one I looked at, I launched those two springs more times than I care to mention, however forewarned is forearmed, so this one came as no surprise, and I even remembered which way round everything went without having to dig out my pictures of the first teardown.  If you are aware of the issues and take care to do things very gently, the calendar works go back together reasonably easily. I did mange to gocha myself with the keyless works by pulling the crown out with the stem in the wrong position, but I knew I had been an idiot the moment I did it, so I only managed to indulge in that one screwup. The watch is running well, but I haven't attempted to adjust it yet. Beat error is around .1 to .3ms and it kept up a good pace, within 20 seconds or so over the course of the day even without me tinkering with it. I'll let the lubrication settle and do a bit more with it tomorrow. The amplitude is still a little low at around 240 fully wound, so there is scope for a little improvement in that too. The other one runs around 270, so there is no reason to think this wont. I have an almost complete spare movement, including a mainspring, etc.so if I need parts I have them.   That red and gold Poljot on your "About me" page is a cracker, as are the others in your collection.
