March 16, 2014 Meeting
Southminster Presbyterian Church
12250 SW Denney Rd • Beaverton, OR 97008
[Corner of SW Hall Blvd-come in the front door]
The topic for my presentation will be a continuation of the last presentation that I hosted on the topic of Mainsprings for Clocks and Mechanical mechanisms.
In many of the Horological Publications, We read and understand the importance of ensuring that the mechanism is clean, condition of the Arbor Pivots and Bushings, ensuring the Escapement is properly adjusted, the mechanism in beat and regulated to the correct beats per hour. Many of these publications do not address the importance of the Mainspring and associated components. How the condition/wear of the Mainspring, Mainspring Barrel Bearings, Winding Arbor Pivots Bushings in open Spring mechanisms, affect the performance of the mechanism. Without addressing these wear areas of the Power source, Mainspring & Barrel assembly if so equipped, no matter how well we clean the mechanism, polish/burnish pivots and adjust the Escapement the mechanism will not perform as designed.
