• 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.

telechron Master Type B

T

telechron.com

I have a Telechron B type master clock that I need to repair/replace the rotor. Since this clock is a bit difficult to work with I was wondering if someone could tell me in advance what to expect when I take out the current rotor. For example, will the mainspring unwind when I remove the rotor (I don't have the winding key)? Does someone know the exact rotor model? Does it have a gear on it? I'd like to take the "B" down and replace the rotor in one step and then get the rotor repaired. I have several rotors on hand that I could potentially use as a replacement. Any help would be appreciated.

Pictures of the "B" are online at http://www.telechron.com/telechron_b.html

Telechron....use the "Find" button above and look at the previous postings on "master clock B". The rotor is the 1 rpm type B. Its been awhile but I seem to remember that the shaft is plain and the large gear is fastened to it by a screw..the spring will unwind when you remove the rotor. The key is a standard size 6 or 7. This is a little tricky movement as one part runs in two directions. Take a few photos or notes before taking it apart...Let us know how you make out.....

I took apart the Telechron B and here is what I found:
1. You don't need to take the movement apart to take out the motor. It unscrews from the front (two screws holding in a small platform) and can be dropped down to the pendulum area. I took out the movement before realizing this.
2. The rotor is a "B" type 1 RPM with a gear that screws on. The shaft is solid.
3. I replaced the rotor with a quiet rotor from another clock.
4. The only problem I had was that the main gear wheel has some play in it and it took some time to make sure the two gears were meshing properly.
5. The mainspring will not unwind when you take out the motor. It turns out it is pretty well balanced especially in a horizontal position.
6. Just in case you've never dealt with one of these clocks before, the pendulum suspension spring is screwed onto the pendulum shaft. Don't try to unhook it, you'll break the suspension spring.

Thanks for your help. Clock is up and running.

Telechron.....good to hear....its been 3 or 4 years since I had one of these so your notes are good for future reference.....

Now the trick is to keep that "big" hand on Zero.

Good luck......

Hello Telechron.com

Weclome to the message board, you will find some very intersting facts and your contributions are apperciated.

I also have had to deal with a Telechron B and found that I had to be carefull since I had to replace a broken spring aftern someone left it pluged in after the pendulum had stopped and it continued to wind. They are very intersting clocks and can be great time keepers.

Hope to see more of your postings in the future.
