Group,
I Have an Ithaca Calendar clock with a Welch Movement. The Striking Main Spring broke and I’m ready to take the clock apart to replace the spring. Before I do though, I’m confused over the strike operation.
Background, I have the DVD’s (Bob’s) and have watched them. Also: The warning for the clock was always close (5 min) to the hour and the hour and half hour always was a couple of minutes late. The Clock was repaired before I bought the clock.
Observation : The pin that rotates on the hour shaft contacts a cam that pushes the J-Hook to first “warn” and then strike. However, the cam’s flat side (not the gradual lifting side) is the part that first contacts the pin? Shouldn’t the cam side with the gradual slope be the one to contact the pin ?
I wound up the time side some with the letdown clamp on to observe the time action and it hits the flat (90 Degree) side first as the clock runs. Is the clock running backward so that the cam’s slope is contacted first ?
