Is the movement completely assembled?Please also look at my latest video to see if there is something else I should do. The strike will not release unless I help it. In the video I push down on the chime shutoff to release it. Thank you.
The problem may be with the chime correction part of the movement (integral pieces not installed).
Herschede movements are kind of quirky and did not operate within normal bounds.
Your solution should be found in Conover's writings on that movement.
Have you read and studied the chime/strike sequence with those writings?
If ever I am faced with a problem that I evidently cannot solve, (This is post number 51 on the subject) I will hit the books or send the movement to someone more qualified.
Is this your clock or are you learning on someone else's clock?
Best,
Dick
