Hamilton Model 21

New escape wheel
New passing spring
New balance cock screw
New dial screws (modified and refinished existing screws, re-tapped holes in dial)
New balance spring stud screw (modified and refinished an existing screw)

The teeth on the original escape wheel were worn beyond safe locking and so I made a replacement wheel with fly cutters matched to the original.

The new balance cock screw, thread cut on a Myford Super 7 and slotted, shaped and finished to match the other screws in the movement (an original plate screw on the right as an example)

A swing tool I made to finish the teeth and crossings, held between centres in a set of turns.
