Plans for Clockmakers' Tools
01/1 DIVIDING HEAD for cutting pinions on a vertical slide on the lathe. Could also be used in the milling machine. Uses a 1/4" or 3/8" capacity Jacobs chuck to hold the workpiece, and shop-made dividing plates about 2-1/4" diameter. (US$8.00/Cdn$8.00, $8.53, $8.61, $8.76)
08/1 CLOCKMAKER’S TURNS. Although rudimentary compared to a modern metalworking lathe, this is the sort of tool clockmakers used hundreds of years ago. It is useful even today for pivot dressing, poising, etc. (US$8.00/ Cdn$8.00, $8.53, $8.61, $8.76)
02/4 CLOCKMAKER’S LATHE, or "THROW". A small dead center lathe with accessories. The best tool for turning pivots, truing up worn pivots and "re-pivoting", and turning small items with hand gravers. The bed is made from a 9" length of 1/2" x 3/4" CRS bar. Center height is just under 2". (Could be scaled up somewhat, if you wished.) Several accessories are detailed, as well as the basic lathe. This little lathe is intended to be powered with a sewing machine motor, Foredom tool motor, or similar. US$16.45/Cdn16.45, $17.55, $17.71, $18.02)
07/1 MILLING SPINDLE. Intended to carry multi-tooth cutters such as one would use for cutting pinions by direct division on the lathe. Body is about 3/4" x 1-3/16" x 3". Ready-made ones can cost a bundle. (US$8.00/ Cdn$8.00, $8.53, $8.61, $8.76)
03/01 DEPTHING TOOL. For testing proper depthing of unmounted wheels & pinions, and for laying out recoil pallets. This sheet also includes a clear explanation of W.J. Gazeley’s simple method of carrying out this task, plus extra notes detailing how to use this same method to lay out pallets spanning any number of teeth of an escapement wheel of any tooth count. (US$8.00/ Cdn$8.00, $8.53, $8.61, $8.76)06/01 Clockmaker’s BENCH & VISE STAKES. This drawing shows 4 different types large and small round ones ("bench block" style), plus two types you would use in your bench vise a one-piece rectangular type, and a 2-piece split type. These are useful, and sometimes indispensable, for example when removing and fitting drive fit collets, pinions, etc. ( US$8.00/ Cdn$8.00, $8.53, $8.61, $8.76)
05/01 MAINSPRING WINDER. A simple and positive tool. No ratchet to cut, and positive hooks for the outer end of the spring.(US$8.00/ Cdn$8.00, $8.53, $8.61, $8.76)
09/1 FLYCUTTING FRAME. Mounted on the vertical slide, this device is used to cut the teeth into a clock wheel blank after it has been turned to the correct O.D. in the lathe. The advantage of this approach is that the wheel blank remains undisturbed in the chuck throughout the turn-to-size and tooth cutting operations. The single-point cutters used are easily made from 3/16"ø or similar size drill rod. (US$8.00/ Cdn$8.00, $8.53, $8.61, $8.76)10/2 FUSEE CUTTING ENGINE. This neat little hand powered machine mounts in your bench vise, and cuts the groove in a fusee blank previously turned to a desired profile. (US$10.85/C$10.85, $11.57, $11.68, $11.88)
11/1 TAPPING TABLE. A simple bench mounted device for ensuring that taps go into a job truly perpendicular. Very small taps can be used with such a device with little fear of breakage due to misalignment . (US$8.00/ Cdn$8.00, $8.53, $8.61, $8.76)
21/1 MOVEMENT HOLDER. This handy device will hold the "bottom" movement plate solidly when assembling a clock movement on the bench. Holds anything from a 2" drum movement to a large longcase movement. (US$8.00/ Cdn$8.00, $8.53, $8.61, $8.76)
18/1 CLOCK HORSE. A convenient stand for testing longcase movements. Stores away flat when not in use. Simple and effective for the job it does; a real asset to your shop, and easily built in a single evening. (US$8.00/ Cdn$8.00, $8.53, $8.61, $8.76)
19/1 SMALL PIECE VISE. Can be hand held, or clamped in the bench vise, to hold small work and/or raise it to a convenient level for delicate filing, etc. Particularly useful if you are using a magnifying eyepiece. (US$8.00/ Cdn$8.00, $8.53, $8.61, $8.76)23/1 METAL SPINNING TOOLS. You’ll be amazed at what you can do with these simple tools, if you know how to spin sheet metal. Make beautiful spun pendulum bob shells, bells, etc. Shows tools required, as well as "how-to" notes for those who have not yet tried it. It’s fun, and surprisingly easy! (US$8.00/ Cdn$8.00, $8.53, $8.61, $8.76)
24/1 OFFSET TAILSTOCK CENTER for your lathe. Provides an easy way to turn non-critical tapers on arbors, pillars, etc. Offsets about 0.4" from zero. (NOTE: this item is similar to the one detailed in TMBR#2. GBL) (US$8.00/ Cdn$8.00, $8.53, $8.61, $8.76)
25/1 CLOCKMAKER’S HAND TOOLS. Shows 13 useful small tools for the clockmaker and repairer. Pullers, pushers, pliers, punches, hammer, piercing saw table, etc. (US$8.00/ Cdn$8.00, $8.53, $8.61, $8.76)04/1 CLOCKMAKER’S DATA SHEET. Provides much useful information including wheels and pinions, chain wheels, contrate wheels, pendulums, etc. Post it on the workshop wall. You will want to have a copy. NOTE: This sheet is accompanied by a "freebie"; another sheet giving info on sources of clockmaking supplies, periodical publications of interest to clockmakers, etc. (US$8.00/ Cdn$8.00, $8.53, $8.61, $8.76)
Plans for Clock Movements, Clock Cases, and Sundials
12/5 SKELETON TIMEPIECE. An 8-day going barrel skeleton clock with recoil escapement. The frame design is simple but elegant, and does not require a daunting amount of fretting out. Completed clock fits under a standard, readily available "400 day" glass dome. (US$19.25/CDN$19.25, $20.53, $20.72, $21.08)
13/6 BENJAMIN FRANKLIN CLOCK. A 30-hour version of Ben Franklin’s well known 3-wheel single handed clock, together with a simple case. An unusual timepiece. (US$22.00/Cdn$22.00, $23.47, $23.67, $24.09)NOTE: If the plans for the Ben Franklin Clock movement interest you, and if you already have, or are ordering, the book Clockmaking for the Home Shop Machinist, you do not need to order these plans, because you will find full details for making this movement in the book. GBL
15/5 JAMES FERGUSON CLOCK. James Ferguson’s unusual single-hander, with a window showing the hours. Weight driven, with an endless chain. Drawings cover movement and dial only. This movement can be mounted in a wall-hung box case (see next item below), anchored to a shelf, or could be used in a "grandfather" style case. (US$19.25/Cdn$19.25, $20.53, $20.72, $21.08)
17/2 HOODED WALL CASE. Designed specifically for the James Ferguson movement, this case will accept any longcase movement with a 12" square dial. Easily adapted for a larger or smaller dial. (US$10.80/Cdn$10.80, $11.52, $11.63, $11.83)16/8 FROMANTEEL TIMEPIECE. Based on a clock dated 1658, by Ahasuerus Fromanteel. An 8-day going barrel movement with verge escapement, cycloidal cheeks and a false pendulum showing in an aperture in the dial. The drawings detail both the movement and a period "Architectural" style case. Austere but elegant, this clock would look good on any mantlepiece.(US$27.50/Cdn$27.50, $29.33, $29.60, $30.12)
26/6 MONTH GOING SKELETON TIMEPIECE. A sturdy little "double barreled" skeleton clock design using twin going barrels driving a common pinion to supply the necessary power.

(US$22.00/CDN$22.00, $23.46, $23.68, $24.10)
(Note: If you want to make one of these interesting little Ring Sundials, you may also want to have the plans for Nicholas Kratzer’s Polyhedral Sundial #22/3 which is accompanied by several sheets of info on The Equation of Time, and other info that I think you would find helpful to an understanding of the Ring Sundial project.GBL) (US$9.55/CDN$9.55, $10.19, $10.28, $10.47)
