Maine Chapter 89, NAWCC

Clock Repair Course F101

This document replaces the Handout distributed at the January membership meeting.

 

General Information:

 

Chairman:  James Lea

 

This is a practical educational outreach program.  The workshops are based on the NAWCC Field Suitcase Workshop outline.  The overall objective of the F101 courses are for students to learn how to repair ONE common eight-day time and strike pendulum clock.  Material presented will cover:

 

·         Recognizing an American time and strike clock.

·         Proper removal of the movement (mechanism) from the clock case.

·         Properly elimination of any power (mainspring) from the movement for safe examination and disassembly.

·         Examination of the movement and identifying problem areas.

·         Part identification and nomenclature.

·         Identifying potential mechanical problems.

·         Disassembling the movement and part labeling.

·         Addressing problems identified and how to make those corrections.

·         Cleaning the movement and mainsprings.  ~Mainsprings are the one real safety issue.  Make sure the students can and will know how to properly remove and clean.

·         Once all problems are identified and corrected, then cleaning the movement again.

·         Assembling the movement.

·         Checking for proper strike function and timing of the movement.

·         Installing the movement back into the case and checking for quality of sound and testing for timekeeping accuracy.

 

Please see the schedule for dates.  All classes will run from 9 AM to 4 PM.  Please bring your lunch and beverages with you, as there are no facilities for purchasing them at the site.  There is no charge for participation.

 

Workshops will be held at the Community Room, Senior Health Center, 58 Baribeau Drive, Brunswick, Maine.

What to Bring

You are encouraged to bring your own “problem child” movement for evaluation, a small assortment of your own hand tools, a small notebook, and a pair of safety glasses.  Workshop Leaders will provide handout materials and some of the machinery used during the hands-on instructive workshops.  Taking notes is strongly encouraged, as is using a digital camera.  Although the demonstrations will NOT be complete repairs during the course of any ONE workshop, they will, nevertheless, be valuable tools for you to use in your own shop.  For a list of parts and tools, please go to our website,  www.NAWCC89.org or contact James Lea.
