Introduction to Chime Clocks


This course introduces the student to chiming clocks, with spring powered or with simple weight driven wall and floor clock movements. F103 contains more hands-on practice and assembly time because the prerequisite courses have prepared the student with an abundance of repair procedures
certainly applicable here. Complicated floor standing weight driven clock movements with tubular or bell chime are not for this class and will not be accepted. A student may have time to work on more than one clock during these four-days. We do not recommend Hermle, Urgos & Kininger movements because the manufacturer does not always recommend they be repaired. Clocks must have pendulums; floating balance type escapem
ents are not permitted.

Prerequisite: F101 & F102. If the perspective F103 student has not completed F101 & F102, they should not apply for this course.
