When re assembling 18s movement I have trouble with the pallet fork during assembly with some movements because of the balance wheel bottom jewel hub have been removing top pallet jewel before assembly to manipulate it into the hub easier but still concerned about bending pallet pivot or dislocating pallet jewel any one got an easy way to install pallet fork during assembly

I turn the top plate upside down and put the pallet fork on it. I use a small piece of rodico to hold it in place. Then I turn the top plate over and assemble it to the bottom plate. Works great. IHC member Gene Buffard taught me that.
I talked to another watchmaker who assembles everything to the top plate, then attaches the bottom plate. He basically does the entire assembly upside down.
Good luck.

Hi JefF , Rodico is my favorite , another method is a C-shaped clip that can be made from an old mainspring and used like this picture shows,I hope this helps

I have a spring like Kevin has pictured. I have come up with a system I use and like. I have a small round magnet a little larger than a BB and I put it on the outside of the plate in the pallet fork jewel and it hold the pallet fork in any position I move the plate. I always demagnetize the watch so it does not hurt anything. I would not try this method unless you have a way to demagnetize the watch.

Rodico, springs and magnets? You guys are scaring me. An 18s movement should be put together on the top plate, then put on the bottom plate. None of the above things mentioned needs to be used.
