  Both of the pivots on the balance staff are
broken, and the cylinder is partially bent out of
place (

bent back into shape, then the staff assembly is
press out of the balance wheel (
see Fig. 2 and 3).

  The staff is now separated from the wheel

the cylinder using a special stake, and now can
be measured for patterns to turn new pivots (see
