Pallet cock

Recommended Posts

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.

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.

    • Look carefully at the tube end?? It appears to me to have a fragment thread visible? Either that or a step just away from the end? I can imagine a chamfer, but a step seems odd - but I've never seen the tubes used on these.
    • This is a very valid point and a subtlety that I was unaware of until fairly recently, learning all the time, the video below explains this point well:  
    • You don't have to use his special tester. Any good multimeter would work.
    • Yes, it looks like GT Revue 30. Doctor, You can not replace escape wheel by the dimensions You listed. One needs to know much more things like number of leaves of the pinion and it's diameter, the position in high of the table and the pinion, the hight between the pivots, the exact pivots diameter... And then, even if suitable wheel is found, one will need to know how to adjust the pallets position correctly. Restoring antique movements is something different than replacing parts. In older movements parts are not interchangeable, this means spare parts do not exist. Here the case is different, but still escapement adjustment will be needed if a wheel from a donor is found. So may be it will be easier to restore the donor for You...Restoring antique movements usually means making of the parts needed and this requires knowlage and working on lathes skill. In this case repivoting of the wheel is the natural solution, but there is a long way that one must walk untill getting ready for such work.
    • I was looking at Essence of Renata, a chemical used a lot for cleaning hairsprings: "Specially prepared solution for degreasing watch and instrument components. Indispensable for degreasing hairsprings." Looking at the MSDS you can see this is just pure n-Heptane, so could be an option for those who don't want to use the chlorocarbons or hexane?     HF6013 - Horological Essence COSHH Safety Data Sheet Horological Essence_0.pdf
