• 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 have a Halblang Clock. About three teeth on the time side barrel are broken or bent down. How do I ID the Barrel so I can replace it? Thanks

Welcome to the board.

It would be easier and quicker to repair the damaged barrel. If you can't do it yourself there are many repairers who would be able to do it for you.

But it would be so helpful to see some photos of what you are dealing with.

Hey JTD,
Here are some pictures. I would like to fix it myself. I can't learn by letting others do it for me,(may have too). Not sure what direction should go. Can I braze some Brass to it and file teeth? Should I cut a 45 degree grove and solder a piece of brass than file? I don't have a clue what materials I need or anything. Thanks JTD
Larry

Hello Larry,
Click the link below for a recent discussion about missing barrel teeth.
Missing barrel teeth are usually an indication of severe shock to that wheel train. Barrel teeth do not just fall off.
The shock that caused the bent/missing barrel teeth may have been from a spring breaking, the click assembly failing, a pinion on the next wheel in the system or many other things.
If you only repair or replace those teeth, the root problem may come up again and tear up teeth on another part of the barrel.
Primarily, you should find out what caused the teeth problem on the barrel.
In addition, the shock that caused the barrel tooth problem likely caused other secondary damage to that movement. Damage like a bent arbor on the second wheel and possibly the third arbor in that train. There may also be damage to the second pinion teeth, the second wheel teeth and so on.
Both wheel trains in the clock you are working on likely have been wound the same number of times in the last 100 years or so.
It is a fair assumption that other train is likely to have the same fault that caused your current problem and that may fail soon.
If you are a novice clock repair person, I would suggest you visit your local library and read all you can about clock repair.
Clock repair is not a simple matter of clean, oil and adjust.
If anything those are minor functions.
Best of luck with your interest in clock repair.

Read This Tutorial on how to make a dove tail. That will be a good option for you. Bear in mind that for a barrel, you have to first take the barrel apart ... at least it's easier that way :)

For multiple teeth, just make a bigger dovetail ;)

Ok Thanks. I've taken the barrels out of the movement and all parts are marked with a #3. The arber is marked also with a 1 5. Maybe someone out there has a barrel or can fix this one.
Thanks Larry
