Another Complicated Job

A customer from the US sent me 3 pocket watches and an Omega automatic watch for repair. One pocket watch needs cleaning and glass replacement while the other one is heavily damaged by rust and when I opened it I discovered a damaged balance staff and damaged pallet staff.  Here in the pictures you can see how I made the replacement parts with my lathe both the balance and the pallets staffs.

 I used several chemicals to remove the rust without scratching any surfaces.

 I started turning the lathe and slowly the new staff is taking its shape.

 After completing the staff I installed it to the balance and run several tests with my truing caliper.

 Now the balance has good motion with the caliper.

 Next is the pallet staff. You can see that the other pivot was rust eaten and could not be trusted anymore.

 So I selected the right blank staff for a replacement.

 After a while in lathe turning this is now the result. A new staff.

 Finally threaded it to the pallet. Take note of the square pivot and shoulder. The result of using A-1 tools.

 The movement is now running smoothly after the cleaning and oiling and with the new parts in it.

 Now the final task is to make a new casing screw like the one in the pic which is rust eaten also.

 Again, with the help of my lathe I was able to make a new screw.

 I've chosen brass material so that it won't rust anymore.

 Now the screw is in its place securing the movement to the case.

And that's how I made it with the help of my tools seen here. Hope you enjoyed it, thanks.
