“mainspring winders”

Several different types of mainspring winders will be covered in this class with demonstrations of their use and discussions on the positives and negatives of each.  Safety, when handling hole-end mainsprings and mainsprings in barrels, is a prime concern which is followed closely by being able to prevent damage to the mainspring or parts of the movement.  Winders covered will be the Ollie Baker, Bergeon, Horolover, and several  home-made winders.
