• 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.

Hi Folks, best wishes for 2017.

I have a Haller aniversary clok in for repair for the charity shop. The Original bronze spring is broken.
The former repair guy has tried to solder the spring to the top block and bottom block. They had glued the balll arms of the pendulum. So it was not possible to adjust speed. I've looked in the 10 edition of the horlovar guide, but was not able to find this backplate. I like to know wich spring I need. I have already removed the glue.
Thanks for any info.

There isn't an exact match in the guide. The closest are probably plates 1162 and 1162A. I think Terwilliger's stock of example clocks likely didn't have a lot of these newer Haller variants.
Anyway. You'll be looking to use a Horolovar .0038" spring, configured as per suspension assembly #33 in the guide.
Adjust the suspension bracket so that the impulse faces of the pallets are 1/3 or less of their way in imparting impulse when the anchor pin is manually held in the center position. Try to get it in the same place on both pallets.

Hi Martin, thanks for your quick answer.

I have the .0036 in house. I will order the .0038 spring.
