Horological Milling Machine Bushing and Depthing Accessory

The basic concept of this accessory is to use a small milling machine to do the job of several specialized clock and watch repair machines. With the Sherline mill, you can maneuver and align your clock and watch parts easily and accurately. You can also machine your parts more accurately in regards to the size and location of your bushing hole. When the machine work is done you can also use your milling machine as a manual press to insert your bushing. This accessory also makes depthing easier and more precise, allowing you to locate your gear exactly where you want it. You can also check the gear mesh with the mating gear and then machine your bushing hole exactly where you want it to be. By using the Horological Bushing and Depthing Accessory in conjunction with your Sherline mill, you now have a three-in-one clock and watch repair machine that is also a fully functional milling machine.

W. R. Smith T-Rest

A T-rest is used by watchmakers to support a hand-held cutting tool called a “graver”. World-renowned watch- and clockmaker, William R. Smith has designed a T-rest especially for the Sherline lathe. It is constructed of solid steel and clamps to the lathe’s bed in seconds. If you are interested in watch or clock repair or construction but wanted a tool system more versatile and less expensive than a jeweler’s lathe, this T-rest makes a Sherline lathe a most attractive choice.

A graver can also be used by any metalworker for hand turning unique shapes on the lathe. It looks similar to a small wood-turning tool and is used in a similar fashion while rested on the T-rest. To learn more about using the T-rest and about how to make your own graver, see the links below.

WW Collet Sets

We manufacture our collets to standard WW specifications (these collets are not hardened); however, we have come across collets that are called “WW” but will not fit our drawbar and adapter. Sherline collets have a shank diameter of .312-.313 and a .275-40 thread. Be sure to check WW collets made by other manufacturers to be sure they fit our adapter before you purchase them. Sherline manufactures a slightly larger .315″ adapter and drawbar set (P/N 1163) that will accommodate some of these other brands of 8 mm collets.

Complete Metric WW Collet Set (P/N 1180)

The Sherline metric WW collet set contains 77 collets sized from 0.3 mm to 8.0 mm by 0.1 mm increments plus a blank collet that can be made into any size collet by the user. It comes in a finely finished hardwood box with 96 holes, leaving room for other collets should you have extras or inch sizes to store.

Rotary Table Collet Adapters

This collet fixture is particularly useful for clockmakers cutting gears on a gear blank that has a pinion shaft attached that can be held in a collet. A bushing is provided that fits into the center hole of the rotary table and helps center the fixture on center. T-nuts and attaching screws are also provided for clamping the fixture in place in the rotary table or mill table T-slots. They are available in WW collet and 8 mm collet versions.

Collet-to-Live Center

These parts are not designed to fit Sherline lathes, but rather are made for watchmaker’s or jeweler’s lathes that have tailstocks that accept 8.0 mm or 10.0 mm collets.

Collet Pot Chucks

These collets can be easily machined and are specially designed to hold larger and odd-shaped parts. A 1/8″ (3.17mm) dowel pin is included with the collet to close on while the face is being machined. The face is drilled 3/16″ deep or less and then bored to exact size to make what is, in effect, a custom chuck for parts too big to be held in regular WW collets. They are used with WW collet adapter and drawbar. See P/N 1161.

NOTE: Collet pot chucks are designed to hold material only on the face end, not through the collet. Maximum gripping depth is 3/16″ (4.8mm).
Sherline also makes a WW collet with a 1″ blank that is deeper than the pot chucks and is not split. It can also be modified to hold tools or parts for special tasks. See P/N 2083.

Clockmaker’s Gear-Cutting Arbors

P/N 2095 and 2096 are primarily designed to be used on watchmaker’s lathes that accept 8.0 mm or 10.0 mm “D” collets. The P/N 2094 Gearcutting Arbor with its #1 Morse taper is designed for use on your Sherline Lathe. With the use of a P/N 1156 8mm Adapter, the P/N 2096 8mm arbor can also be used on Sherline lathes, although the normal system for mounting chucks is recommended.

Sherline Collet-to-Thread Chuck Adapters

These arbors are not designed to be used on Sherline lathes, but rather are specifically suited to the types of lathes often used by jewelers and watchmakers.
The 3/4″-16 Arbors provide a way to mount a Sherline 3-jaw or 4-jaw chuck to this type of lathe. The 3/8″-24 arbors allow a 1/4″ or 3/8″ Drill Chuck to be mounted. The ability to mount these chucks adds a great deal of versatility to this type of special-purpose tool.

WW Collet-to-Thread Chuck Adapter

The WW to 3/8-24 thread collet adapter is the same as the 8.0 mm to 3/8 x 24 thread adapter (P/N 2092), but with a smaller barrel diameter, so it will work with our Sherline lathe.

Other Uses for Sherline Chucks

A customer is using a Sherline 3-jaw chuck on a variable-speed motor with taper shafts as a “lathe” setup for his custom jewelry business. Sherline Products does not offer the variable-speed motor.
