• 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.

    Perivale/Bentima beat rate question

    Can anyone tell me the correct beat rate for this Bentima three-train mantle clock with English Perivale movement, please? By successive approximation I’ve arrived at 10,300 BPH but it would be nice to know the correct figure as I don’t have the luxury of a fortnight to spend on regulation! A...

    Garryflex for polishing pivots

    Garryflex is a rubber compound impregnated with silicon carbide abrasive particles. The Museum, where I work as a volunteer horologist, use it for cleaning rust etc from cast iron and other artefacts, and they gave me a piece of the 240-grit material. A finer 320-grit version is available too...

    Kern & Link standard, dial restoration advice

    I was very lucky to have been given this 1932 Kern & Link plate 1667 standard 400-day clock. It's the early model, having no pendulum locking mechanism or levelling adjusters. Apart from being very dirty, it is complete apart from its missing dome, and I am just embarking on restoring it. The...

    1954 M Reiner with odd hands, perhaps?

    I've just finished this M. Reiner plate 1457 which I bought because it was an attractive-looking clock with unusual hands - I particularly like the 1950s 'circle-in-circle' design. However on cleaning the parts the minute hand has been repaired by soldering, and I'm wondering if these hands are...

    400-day clocks in a cold environment

    Hello everyone, I haven’t posted for the best part of three months, due to my wife and I having caught Covid-19. Better now! However whilst I was incapacitated, I noticed that a couple of my restored 400-day clocks had stopped. I re-started them and they ran, but the escape wheels were moving...

    “Bentima” (Kern und Sohne) standard - 1961

    I acquired this very cheaply (£15) as a ‘practice clock’ and it’s my first standard, as I’ve only worked on miniatures and midgets before. It turned out to be a Kern plate 1340D from 1961. On arrival, the clock was complete but wouldn’t run due to gummed-up pivots, and rust on the anchor pin...

    Horolovar ‘Beat Setting Tool’ tip

    I have one of these tools designed for setting the beat on 400-day clocks, and have struggled to get it to work properly. It’s quite flimsy, and its grip on the saddle isn’t good, so that when moving the tool’s handle I can’t be sure if it’s actually turning the saddle, or just slipping round on...

    Polishing scratched acrylic domes

    Can anyone recommend an effective polish for renovating scratched plastic domes fitted to later 400-day clocks, please? I’ve seen “Novus” products recommended, but I can buy a new dome for a quarter of the price! I am hoping that household products may work. I have a range of metal polishes to...

    "Tempex" Bulle clock

    I've agreed to try to get this clock going. Detailed inspection reveals that it is basically a Bulle movement, serial number 299331 which dates it to 1939, but with some differences in detail. By all accounts, Tempex was a brand marketed by the British battery manufacturer Exide in collaboration...

    400-day clocks - mainspring matters

    My experience with 400-day clocks is limited, but growing. The last two I’ve restored, both miniatures – a Kundo and a Koma with deadbeat escapements - have exhibited similar problems after fitting a new suspension. Essentially the issue boils down to weak impulse. I cleaned these clocks...

    S Haller “Elo” midget escapement question

    I’ve just acquired this clock, which matches Plate 1521 in the Tenth Edition of the Guide, but is definitely a midget and requires a new Horolovar no.44 suspension unit, as the fork and bottom block are missing too. While this is on order, I’ve dismantled the clock to clean it. I have found...

    Metamec model 701 from 1955

    I have an 8-day Metamec clock which I serviced a while ago and it keeps excellent time, so on a whim and for a few pounds I bought this 30-hour time-only example which was the first model of clock made by this popular British manufacturer. The design first appeared in 1947 in synchronous...

    Koma miniature - bent T1 arbor

    I’m repairing a friend’s Koma anniversary clock. It has at some time lost a ratchet wheel tooth, and the resulting impact has bent the T1 arbor. How can I safely straighten this? My first instinct says “protecting the pivots, support it over the vice jaws and using a drift, hammer it back...

    Small cuckoo clock

    This came to me as a gift, in pieces! It had been stored away for many years. The weights were wrapped up in some newspaper dated 1971. At a guess, the clock is fairly modern (1960s) although it has a countwheel strike. The bird is made of plastic. The case needs more repair than the movement...

    E N Welch beat rate question

    I have replaced the suspension and leader of this 8-day Welch movement, and it is now going well. I am in the process of regulating it. Does anyone have any data on the correct beat rate for this clock, please? The nearest I can get by successive approximation is 178 BPM (10,680 BPH). Is this a...

    Seth Thomas 'Joker' hairspring question

    I've completely overhauled this clock, replacing about 15 bushings and 18 trundles, and it goes beautifully but now I'm having trouble with its rate. Basically, it's galloping along, gaining 5 seconds every minute! The original hairspring had broken, just next to the collet. I managed to open...

    Idea for closing trundle holes in

    I've always found closing the holes in the shrouds after replacing trundles rather difficult. Some advocate knurling, while some use LocTite. I hit on an alternative recently, which saved me a lot of time as I had to replace 18 trundles in a Seth Thomas 'Joker'. I bought a really cheap set of...

    Sterling Croydon synchronous mantle clock

    This clock has been in my round-tuit pile for a couple of years, and I have just got around to it. The movement has a single centre-hole fixing that had completely corroded away, leaving part of the thread firmly stuck in the cast alloy front mounting plate. The three bolts securing this plate...

    Kundo miniature 400-day clock

    Someone asked me to repair their Kundo but I had to decline, as I’d never worked on a 400-day clock. So I bought myself a non-working example very cheaply on which to practice. It proved to be a steep learning curve and took me far longer than I anticipated, but having got it going really well...

    Kundo miniature 400-day clock advice please

    This is my first attempt at repairing a 400-day clock and I should appreciate a bit of advice, please. I bought this mid-1970s clock cheaply as a non-worker for practice, knowing that it had a broken suspension and it came with no key or dome. On the other hand, it looked very clean and my...
