• 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.

    That's such a useful yet not so obvious tip. Thank you sir!

    Cuckoo clock chain length

    Suddenly I have two QQ clocks both gifted to me. I've got them going surprisingly well but 22.5 hours duration isn't enough! I keep forgetting and I have no latitude. The weight is on the floor AGAIN! Does that trick really solve this silly problem of needing to live in a castle to get the...

    French Mantle Clock

    Yes that is in line with my own thinking and that of another interested party exactly. I think its the original movement as its fitted so snugly. The case is slabbed and veneered. Inside the space has bored out as a circular tunnel by some large lathe I should think. There is a space for the...

    French Mantle Clock

    I have hear yet another similar movement. French made "Marque Deposee" serial 6551 - 48 where again I believe 48 refers to the pendulum length. It has a heavy oak veneered wooden mantle case. The movement - which I believe is sometimes called a drumhead , is patterned along the same lines as...

    Post your quartz clock matters here

    Nice clock; Nice project. Martin has covered the ground. If you can make sure the mechanics will work and you have an electronic fault, it might help a little to identify the crystal frequency. I'm betting 4Mhz (by looking at your pictures), in which case you can probably source a replacement...

    Clockmakers Hall of Shame

    I think its an excellent thread too Shutterbug. There's a huge amount to be learnt here and maybe even impart. I read Bruce Alexander again just back there and I am following in his wake when I look at the path he trod. I'm at that point where yes I often know the preferred way forward and then...

    It looks as though a piece has been let in but how come one tooth is reversed. That's weird. Big lumps of solder could have been brushed off while still molten That's ugly!

    Bruce - No arguments from me on anything you said on either topic. I'm here to learn not pronounce at all. In any case one never knows the pressures that applied at the moment. Its easier to take up a definite position - if you can afford to, - or are highly principled. That's not always quite...

    Clockmakers Hall of Shame

    Jimmy Oz has a good point. A specific idiosyncratic ID makes sense. Bruce A. It seems to me that all history is so dark in places that we have a need to gloss over much of it. This obsession with revenge for distant past wrongs isn't very healthy IMHO. Schoolteacher's grandstanding with...

    Oh Bruce you are making me smile. More of a rant but a good one. I'm here to learn and I have done so. That barrel cap could easily be turned over yeah. Looks more of a doodle than a message to me. Old repair marks can be a fascination if the date can be de-coded. Why's a code needed? Why not a...

    Rempe self-winding - questions on electrics

    Thanks for the pics. Great help. I think you're right on to this from what you say. It sounds very good. Soldering is a knack that's easy to lose. I did some myself this week. Its a slick art and this modern silver solder is awful! I sometimes use some Bakers Fluid on older parts - even on wire...

    Blimey matee you're more London than meself! I'm from West London and would not go south without me army. Crossing that River Thames was fraught with danger! I moved down to Sussex and escaped to become a member of the farming community and gentlefolk. Moo! I just though I might be able to...

    Rempe self-winding - questions on electrics

    Fascinating! There I was butting in hoping to help when all the while you're streets ahead of most things I say! No matter I am enjoying this because the issue comes up in one form or another over and over again. The use of DC (Battery) into an inductor or (coil) via a switch (commutator) has...

    Rempe self-winding - questions on electrics

    Gold offers low resistance contacts and is good for switching low currents such as RF. However, I think your currents and BEMFs will not suit gold which is a soft metal and may well migrate or burn away quite quickly. Any spark suppression is a good idea. However when the spark is entirely...
