• 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.

    How does a crutch pushing on the side of a pendulum work? Sattler Mechanica M1

    One clock I've looked at and debated purchasing for years is the Sattler Mechanica M1 clock kit. One aspect of that movement that has puzzled me is how the crutch pushing on the beat adjuster on the left side of the pendulum could provide an impulse for both directions of swing. I've attached...

    Close Slot in Pendulum Leader for Crutch Pin?

    On my parents' grandfather clock, which is circa 1900 and well used, the slot in the pendulum leader has widened to the point that the slot is no longer a close fit to the crutch pin and an audible rattle can be heard going from tick to tock. Click for larger Is there a standard...

    Octagonal Paper Dials

    Is is still possible to obtain dials where the chapter ring and text themselves are arranged octagonally? My mother-in-law gave me the clock below to practice my repair skills with and admitted that years ago she tried to clean the paper dial with common household cleaner. It promptly...

    Standard Bench Key Sizes?

    Partly because I can't find a rust-free, low cost set and partly because I'd like to get more practice on my lathe and mill, I'd like to make my own set of bench keys for working on my pocket watches. However, I don't have any set to measure against for the size of the square ends. Would a...

    How to open case of Colibri double hunter skeleton pocket watch?

    I have a Colibri double hunter skeleton pocket watch that my wife gave me a few years ago that has consistently run a bit slow. Now that I've started learning about watch movements and repair, I was going to see if I couldn't regulate the movement, but I'm unsure how to get to the movement in...

    What collet for Bergeon Reamers?

    I'm trying to price out everything that would be needed for bushing a clock with a mill, but haven't been able to determine what WW collet(s) are needed for the Bergeon reamers. In the few pictures of the reamers I've been able to find online, they are usually in a case, so it's difficult to...

    Bushing with a Mill - Clarifying the Process

    I was hoping to clarify a few points about the bushing with a mill process discussed by Jerry Kieffer and others on this board. This is for regular bushing job, not fixing a bad bushing job that was already done. Here's the process as I understand it with questions intermixed. 1) You find the...

    Seth Thomas Movement - What is this wire?

    I received a Seth Thomas mantel clock to clean and put back into beat from some relatives. This is only my third movement so far, the first two being in wall clocks. When I took a look at the movement, I saw a wire I've not seen before. Would someone take a look at the picture below and tell...

    Starting a Seth Thomas Mantel Clock

    OK, really trivial question, but the answer eludes me - how do you start the pendulum of a Seth Thomas mantel clock if the back is closed up and against a wall? My first thought was hold up one end a bit and set back down quickly, but gently, to set the pendulum in motion. Is there a better...

    Cleaned, Assembled, Oiled, Disassembled Again - Re-oil Pivots?

    A rather long subject line for a simple question - I cleaned a movement, assembled it, oiled all the pivots, and after a few days run time, found a problem I need to correct that requires disassembling the movement again. Now I don't know if I should re-oil the pivots when I reassemble the...

    Main Spring Issues

    I inherited an antique wall clock (see here for more details) that had been "repaired" very poorly. The person my grandfather hired to repair the clock lost the chime-side ratchet wheel, bent and installed two of the levers for the chime works backwards, and didn't clean the movement. In...
