helvetia

Hi

working on a helvetia 82c and the lower balance pivot has come off. I have tried applying it back again but it seems loose.

Whats the best method of securing it. squeeze the lower balance pivot so it grips or just line it up on pivot and push. or something else?

cheers

What you are referring to as a lower balance pivot is actually called the roller table.

It should be a tight friction fit onto the staff.

Hi Gary    I take it you mean the roller table has come off   If so, as Marc says its a friction  fit onto the staff. The impulse jewel is fitted at right angles to the balance cross arms as per the picture.  Unless its been replaced or the balance spring has been adjusted.

If roller doesn't want to stay put, you can glue it on,  use nail polish since it disolves in acetone which wont hurt shelac.

Hi

Oops sorry.

Yer super glue im afraid it just keeps turning and falling off.

[Nucejoe]

No super glue cuz you no longer can remove the roller, super glue ruins the metal of staff and the roller, rust developes and welds them together in couple years.

If the hole in roller table is too large then you got the wrong roller, which even if roller did stay on staff, it wont match with pallet jewels and you get no escapement.

Nail polish is harmless. epoxy glue works.
