Christianson Twice a year your Board of Directors gathers to conduct the business of A WI at the mid­ year meeting in January and at the annual meeting in June. In January of this year it was a real pleasure to preside over a Board that was excited about the future of A WI and the direction we are taking. A new culture of operation is developing within our Board based on collaboration, cohe­ siveness, and trust. Two very important points came out of the meeting that are responsible for this new culture of operation: 1. The understanding that the Board of Directors controls the Institute and the direction that it takes, with the staff (headed by the Executive Director) providing administrative services for the Board. The Board, however, receives its power from the membership, and its own direction from the various committees of A WI. These committees are made up of members of A WI. What this boils down to is: the members are the heart and soul of AWl, and these committees are our source of ideas and direction. There is good reason why the "President's Message" over the past year has concentrated on the functions of the various committees. These committees are the strength of A WI. Without strong committees, A WI has no future. 2. The AWl Mission Statement that the Board of Directors adopted in January states that the American Watchmak­ ers-Clockmakers Institute is the premier international organization dedicated to preserving and promoting the highest stan­ dards of workmanship in the horological crafts. It is the role of A WI to set the standard of excellence in both the instruction and practice of quality horological repair and restoration work worldwide. All of our committees are working toward these ends; it is the first time we have had a clear understanding of who we are and where we're going. As we go along you'll be able to see some very clear and tangible results. I hope you were moved to be a part of one of these committees. If you weren't, you'll have the opportunity again. The key to the future of AWl is in its members. We're striving to be a member-driven organization where the members will have every opportunity to make A WI into the organization that we all want it to be.

Executive Director's Message William J. Ewbank One of my personal heroes was Ulysses S. Grant. I first came to appreciate the man in my extensive readings about the American Civil War. General Grant is most famous for his exploits as a soldier. Few people are aware that his autobiography is considered one of the great works of Ameri­ can literature. Grant wrote the book in a desperate race against time. The last chapter of the book was finished in a painful scrawl just hours before the General succumbed to a long, painful battle with throat cancer. I am saddened to report that another gallant old soldier has gone to his reward. Colonel Roy Hovey, ret. AWl's lathe 1 course instructor for many years, lost his battle with cancer Tuesday, June l5 h. Like General Grant, Roy's last weeks were spent assembling a legacy. The complete Roy Hovey lathe courses, including all equipment, parts, tools, course materials and the intellectual property created by Roy to support the program, have been transferred to the American Watchmakers-Clockmakers Institute for a very fair settlement value. The Roy Hovey lathe program will continue to benefit A WI and its members for many years to come. Roy Hovey was the first A WI instructor and member that I met. When I received a tour of the facilities on my first day at work in the summer of 1996, Roy happened to be teaching his introductory 12-day lathe course to Academy and Project Extend students. With a twinkle in his eye, my tour guide Jim Lubic left me in Roy's care for an introduction to the lathe course. That was my first exposure to Roy's passion for his course and meticulous detail. An hour of lathe course outlines later, I was slumped in a comer muttering, "No mas! No mas!" Roy extended the same meticulous and painstaking care to the expense vouchers submitted for his travel and teaching costs. I once joked with Roy that I stopped reading them and had been reimbursing him by weight. Although we occasionally had disagreements about business, Roy and I developed a mutual respect and admiration. It is truly a sad duty to report to you the loss of a valued A WI member and friend. Roy's work in the lathe program, a major contribution to the craft of horology, will live on. For the man himself, I would paraphrase an old movie line: "We ask the Lord in heaven to take to his keeping the soul of our friend and comrade, Roy Hovey. But Lord, we advise that you not take him lightly."

When the pin on the setting lever reaches the second notch in the setting spring, the arm on the setting lever will be on a plateau on the clutch lever. The mechanism will then be locked into the setting position with the clutch teeth engaged in the minute wheel teeth. (See Figure 5 for this position.) Figure 5 shows the Elgin winding and setting mechanism in the setting position with the clutch teeth engaged with the minute wheel teeth. The arm of the set­ ting lever is positioned on the plateau of the clutch lever and the pin on the setting lever is in the second notch of the setting spring. When the winding arbor is being pushed inward for winding the watch, the pin on the setting lever goes immediately from the second notch in the setting spring to the first notch. This releases the clutch lever allowing the clutch lever to move upward so the clutch teeth can en­ gage the teeth on the winding pinion. The action of the clutch lever spring against the clutch lever causes the clutch lever to shift the clutch pinion into connection with the winding pinion. (See Figure 4 for this position.)

Seth Thomas Hall Clock, Part 45

Leo A. Jaroslaw ©1999 (All rights reserved by the author)

Introduction The clock we will be discussing in this part is a Seth Thomas Westminster Chime Hall Clock. It warrants discussion in this series due to a very different design of the chime and strike controls. Although much of the details are common, the place­ ment is unusual. With the exception of the star cam and the chime lift lever, all the controls are between the plates. The movement of this particular clock is a ST 74G. According to Tran Duly's original Seth Thomas book there are several variations of the #7 4 movement. Mounting of the movement could be on a seat board or a bracket. The pendulum could be mounted on a bracket or on a stud on the rear plate. Some had a second hand, others did not. Some had a moon dial.

The Magic Center Finder, Part 2

J.M. Huckabee, CMC, FAWI, FBHI

Background Part 1 of this subject related the ftmc­ tional details of The Magic Center Finder. This tool is a device designed for the clockmaker to aid his lathe work. The original intent was to speed up and improve the quality or repivoting arbors of mid-size clocks. The device was so successful that it has found wide usage in my shop. It can locate a true center in five seconds "with your eyes closed." In that no other known technique or tool can make that claim, it was named "The Magic Center Finder."

Construction Figures 13-16 begin the process of mak­ ing the bell. We need a precision hole about %" long. That is an impractical depth to drill straight. Therefore it is drilled from each end. It is then reamed to a very close fit to our center-drill di­ ameter. The material for that drill-reamer is spring steel wire of 0.047" diameter. The bit of Figure 15 is 0.043" diameter. This means our reamer will up-size the hole by 0.004". Ream­ ing also straightens the two drillings where they meet midway. Figure 14. Locate and test a true center.

38 Horological Times • July 1999 bushings are identified as friction bushings because the hole for them is made slightly undersized so that friction holds the bushing in place when it is forcibly pressed into the hole. The commercial drill for drilling the bushing hole is called a D-drill because of its shape. A D-drill is shown in Figure 3 together with a listing of the drills in the KWM senes.

Steps in Bushing a Worn Pivot Hole 1. Select the Bushing: Measure the pivot thick­ ness and the thickness of the plates in millimeters. The required bushing can be identified from a look-up table in a materials catalog or a KWM bushing template as shown in Figure 4. The template has bushings mounted around the edge to facilitate testing the sideshake. It is convenient Figure 4. Bushing Template and Look-Up Table in the shop to keep a supply of bushings on hand.

Another time saving tool for seating bushings within 2" of the edge of the plate can be made from the double-action pliers that are part of the older watch crystal mounting sets. The pli­ 00 ers are typically 8" long. New anvils are made for A. Backfile B. Ream C. Drill the pliers as shown in Figure 7. The shape of the lower anvil (stump) is very useful when bushing around the half cock support for the escape wheel Figure 6. Preparing the Worn Pivot Hole for Bushing in early American Clocks.

Spring Barrels An often-overlooked bushing problem is the spring barrel. Both the cover and the barrel itself may require bushing to prevent an interference with the second wheel that will result in severe power loss. Commercial bush­ ings can work but oftentimes it is necessary to make your AWl ··-~-· own. For centering accuracy, I prefer to cut the bushing -· hole in the barrel and the barrel cover on a lathe. In the absence of a suitable lathe, a good job can be done by carefully back filing and reaming to accept the new bushing. Battery Number System Great Wheels/Spring Drive The high pressure of the spring together with poor Booklet lubrication can severely damage the great wheel bushing. $5.00 each In some cases commercial bushings can be used; in others they will have to be made on the lathe.
