• 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.

Hi all,
I had a Hermle movement in wich was come to a stand still because of worn out barrel bushings on the time side. The barrel was all tilted.
Last week I was looking for a lathe, a really small one, but my wife who was with me, said go for a bigger one. The small one had to little power to work with
steel. Sure it is heavy. 80 Kilo's. It is now in the attic. Pew. So now I made My first two bushings for this time side barrel. It was 46 years ago when I was at school working with a lathe, only for 1 year. The clock is in good working order at this moment. Enjoy the pictures. First the holes in the barrel and the barrelcap were dressed on the lathe with a tapered drill so they were centric again. Then bored with a normal drill to size.The bushings were press fitted. The bushings were broached to size the Arbor. See pictures in post above. The text was gone strange.

Nice lathe Jaap, and awesome wife that talked you into a bigger one. Looking forward to seeing more of your work.

It looks like the flange for the cover is on the inside of the cover. I can't recall the last time I did a Hermle, but didn't think there would be room between the cover and the spring for the flange. However if it works that is good.

Hi David,I cheated on the barrel cap. I had a scrap cap from an old barrel which fitted exactly. I broached the hole so it was good. The worn out barrel cap I was just doing for the experience. Was I able to fit a bushing in a thin plate. You maybe correct that the bushing should be pressed in from the out side.

Thanks for reading.

RC makes an excellent point. I always do the final "tuning" with a boring bar. Hog out as much as you want with drills or the step drill that you have, then leave just a bit for boring.

Wow. Very cool. And good memory working from your experience 46 years ago ( I hope I understood that correctly).
Hi Clockrepairforfun, yes I think I was at that moment 14 years old. But I have a lovely wife who studied as a machinist for 4 years at high school. Thank God she has still her books about turning on a lathe. These are very helpfull for me.

You won't find these in an ordinary hardware store unless they have an exceptional machine tool supply section. McMastrer Carr and other machine tool supply places should have these in a wide range of sizes. This is McMaster Carr's selection of very small carbide boring bars: https://www.mcmaster.com/#boring-bars/=16htmf5 The smallest ones have 1/8" and 3/16" round shanks so you may need to use your lathe to make a holder.

Hi, RC,
I will look into it at the store who delivered the lathe here in the Netherlands.
Thanks for the link. I have now a better idea of the boring bars.
Thanks again.

Jaap, you are an inspiration to us all. I had a stroke last summer and lost most of the power on the right side of my body. Being right handed, I have learned/taught myself to work lefthanded to compensate.
Slowly my right side is getting stronger to the point I can now wind clocks righthanded, when there was not enough strength to do this simple task last summer.

Hi Harold,
I'm sorry to hear that you got a stroke last year. I hope you will recover soon from it. It costs me lots of energy, but I keep reaching for new goals with the help of my wife Elly. I need to be busy. I do a lot of clock repairing for the charity shop. I try to set my goals further and further.

I wish you all the best.
