• Important Executive Director Announcement from the NAWCC

    The NAWCC Board of Directors is pleased to announce that Mr. Rory McEvoy has been named Executive Director of the NAWCC. Rory is an internationally renowned horological scholar and comes to the NAWCC with strong credentials that solidly align with our education, fundraising, and membership growth objectives. He has a postgraduate degree in the conservation and restoration of antique clocks from West Dean College, and throughout his career, he has had the opportunity to handle some of the world’s most important horological artifacts, including longitude timekeepers by Harrison, Kendall, and Mudge.

    Rory formerly worked as Curator of Horology at the Royal Observatory, Greenwich, where his role included day-to-day management of research and digitization projects, writing, public speaking, conservation, convening conferences, exhibition work, and development of acquisition/disposal and collection care policies. In addition, he has worked as a horological specialist at Bonhams in London, where he cataloged and handled many rare timepieces and built important relationships with collectors, buyers, and sellers. Most recently, Rory has used his talents to share his love of horology at the university level by teaching horological theory, history, and the practical repair and making of clocks and watches at Birmingham City University.

    Rory is a British citizen and currently resides in the UK. Pre-COVID-19, Rory and his wife, Kaai, visited HQ in Columbia, Pennsylvania, where they met with staff, spent time in the Museum and Library & Research Center, and toured the area. Rory and Kaai will be relocating to the area as soon as the immigration challenges and travel restrictions due to COVID-19 permit.

    Some of you may already be familiar with Rory as he is also a well-known author and lecturer. His recent publications include the book Harrison Decoded: Towards a Perfect Pendulum Clock, which he edited with Jonathan Betts, and the article “George Graham and the Orrery” in the journal Nuncius.

    Until Rory’s relocation to the United States is complete, he will be working closely with an on-boarding team assembled by the NAWCC Board of Directors to introduce him to the opportunities and challenges before us and to ensure a smooth transition. Rory will be participating in strategic and financial planning immediately, which will allow him to hit the ground running when he arrives in Columbia

    You can read more about Rory McEvoy and this exciting announcement in the upcoming March/April issue of the Watch & Clock Bulletin.

    Please join the entire Board and staff in welcoming Rory to the NAWCC community.

Comtoise chime off

This is my second Comtoise clock but first time tearing one down and back together.

Now that its cleaned up - It is keeping great time but the chime ( strikes on the hour and a second one minute to after as well as a single strick on the half hour ) is out of sync with the time. IE .. clock time is spot on but the chime ( accurate strikes) pops off a bit too late. Is there an adjustment I missed in putting this baby back together? Could it be the weights?

Thank you for the help getting me here.. lots of useful tips and encouragement for a newbie.

How much off is your strike? Just a minute or two or more? And is the deviation the same at the full hour and the half hour?

The weights are not the culprits for this behavior.

Buck, I do not understand from your explanation, what it is doing. Normally, they strike the hour on the hour and then again about two or three minutes after the hour. They also strike once on the half hour. Would you explain once again what it is doing on the hour?

Yes of course. The clock chimes about three minutes AFTER the hour - repeats 2 minutes later then again once on the half hour - but with the same three minute delay.

It is the wheel next to the hour pipe. Remove the hour pipe far enough that it will turn without turning the cannon pinion. Then turn it counter clockwise one tooth and slide it back on.

moved the hour pipe.. perhaps a bit too much... I'm gonna let her run and see ( should have marked the darn wheel)
BTW .. I notice that the hour pipe - the cannon pinion and the smaller pinion are all scratched to mark a particular tooth - if they were all aligned would that be the way to go?presumably that would set the hands to 12 ?

If there are original marks on both wheels, yes, they should be aligned. However, it is possible that a later repair person marked them incorrectly, so don't be disappointed if the marks don't solve the problem. The advice given above is good. You may have to find the right spot by trial and error.
