Suspension Springs
NOTE: Suspensions do not have to be exact in lengh, if the clock runs slow then raise the pendulum bob with the screw.
PENDULUM PARTS
Long Suspensions
Pendulum Bobs
This is for the pendulum bob only for a wood stick pendulum. Measurement is from one side to the other.
Top Hooks
These top hooks are all for a wood stick style pendulum except the letter "I" and "J" units. For the most part you would have the wood stick in either 1/2 inch or 1 inch width and put this top hook on it by bending the tabs over as a friction fit. Then the pendulum is all set to be able to hook to the leader. Note: The pendulum assembley consists of the suspension spring on the top, then comes the leader, then comes the pendulum with its top hook attached.
Leaders
To get the length of the leader on a German movement, get the CM number off the back plate of the movement. This measurement is the approximate length from the top of the movement to the bottom of the pendulum. So if you measure the pendulum tip to tip in inches and then add an inch for the suspension spring, the multiply times 2.54 it will give you the CM length of all but the leader. The remaining length from this measurement and the CM length from the back plate, will be the approximate leader length.
