The chimes returned at Trinity Episcopal Church in Williamsport after Jim Zerfing, the church clock's longtime caretaker, and students from Pennsylvania College of Technology climbed 100 feet up the clock tower's narrow stairs to replace parts that had fallen into disrepair. Under the direction of Zerfing and Keith H. English, instructor of machine tool technology/automated manufacturing, students enrolled in manufacturing-related majors remade the gear shafts that hold the minute hand on each of the 135-year-old clock's four dials, made a duplicate bevel gear and helped to install a new motor.
