• 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.

Need a replacement Mauthe spring barrel

I am attempting to replace a Mauthe barrel that has the restraining clip broken off. The numbers on the movement include 42/105, w500 and I assume the serial number 195251. Is there an equivalent Hermle barrel? My measurements of the barrel include 70 teeth, gear side O.D. 46mm, opening side O.D. 42mm and height 23mm. This is the time barrel for a ¼ hour chime movement.

Is this barrel from a old clock? There is a good possibility this could be repaired.

I repaired it once by tapping a screw hole in the barrel and inserting a screw. But the hole in the spring was not large enough for the screw. I enlarged the hole and the clock ran for a year, but then the end of the spring broke off. My experience in annealing the tip end of clock springs has not been good. I would like to replace the barrel and spring if I can find the correct replacement.

You will most likely find keeping the original barrel and simply replacing the spring will be the easiest and least expensive. By “retaining clip” do you mean the “barrel hook? If so, here is the link on how to repair.

Unfortunately that is not a Hermle and no exact Hermle barrel exists

Jime, you do not need to use the original hole to repair it. Drill one somewhere else and insert a new hook. To anneal the outer end of a mainspring, heat about three inches of the end red hot and let it cool on its own. You can then drill a new hole about 1/2 inch from the end, grind the end to form a semi-circle and it will be bendable and easy to insert in the barrel. Finding that barrell may be difficult.
