anyone care to share secrets on easy ways to align pivots when installing the top plate on full plate watches? Thanks.

The first issue to deal with is the pallet fork. For this, you either assemble the movement upside down or you affix the pallet fork to the top plate with a bit of rodico or a clip. From there, it's pretty much like any other movement. Just a bit harder because you are dealing with all the pivots at once. If you are having trouble with a particular aspect of assembly, let us know what that is and maybe we can help further.

Thanks Dave the pallet fork is what is giving me problems I broke off the pivot. I never thought of asssembling the movement upside down i’ll Try that after l get a new pallet fork.
How do you remove the rodico when finished?

As far as the Rodico, you probably just grab it from the outside edge with tweezers. I always use a small strip of Scotch tape to hold the pallet-fork in place. I then do as I said with the Rodico, and grab it with some tweezers. This practice is frowned upon a bit, but does work, and I don't see that it leaves any sticky residue behind.

BTW: There are a lot of parts movements out there that have become that way due to broken pallet-fork pivots. It's a common problem with full-plate movements when one doesn't have much experience with them yet. Good luck.

I put the small ball of Rodico out as close to the end of the fork as possible so it can be grabbed with tweezers when the movement is together.

Hi Tracker,

Upside down is definitely safer with full plate lever movements because of the lever's position, and another useful trick is to hold the plates with rubber bands, not too tightly. This happens to be a verge repeater with a lot more pivots to align, but the principle is the same.

If you do it upside down like this you shouldn't need any clips or Rodico, and the same principle applies when you're dismantling as well.

Regards,

Graham

I also do it upside down.
This way you get the barrel arbor, center wheel arbor and 4:th wheel arbor for free so to say since they are longer and easy to fit. The lever is just like any other arbor since you don't need to fiddle with getting it in the slot of the top plate.
