• 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.

I saw this interesting clock on Facebook this morning. It’s a DIY clock using rollerballs to power an old 400-day clock. The post says all the mechanism is handmade.

I didn’t want to link a post here because the clock is for sale, but it’s worth checking out. See one of the photos for the user and Facebook group.

I've never seen that arrangement on a torsion clock, but Pro Clocks does sell similar designed clocks with balance wheel escapements. A few years back, someone here converted a 400 day clock to weight driven. Interesting stuff! I wonder how often you have to add a ball on that one?

The owner said there 20 ball and it drops about about one a week.

It´s a post WWII Kundo combined with a kind of paddle- wheel weight powered mechanism , certainly the work of a talented clockmaker adding two gimmicks to create a unique eyecatching clock.Yes,You have to put the balls on the upper tray by hand. Devon Clocks in England once produced a clock like that.

So it's a "20-week" or "140-day" clock? Do the balls have to be moved manually to the top?

Kurt
Yes, manually. There’s a video in the post showing the owner moving balls to the top of the clock.

Maybe it’s a setting in your Facebook setup? Do other Facebook videos play? Not that it’s much help, but they play fine for me on an iPhone running IOS 14.2.

The file name is a .jpeg, not a link so its just a picture.
Sorry Shutterbug, I misunderstood your question. I didn’t include a link to the post, since the clock was offered for sale. I added the group and original poster’s name if anyone was interested in seeing the videos and discussion about the clock.

That explains it then :) My internet has been acting up, so I thought it may have been that.
