This page contains watchmakers/jewelers lathes and some accessories that are very useful in pen repair. All are used, but all have been tested by using them for pen repair. They consist of the basic components of a lathe; bed, headstock, tailstock, tool rest and newly installed belt. They do not have provision for mounting the "work." It is left to the users to customize to their own needs. Typically, the work is held by a collet or a three-jaw chuck (more below on these accessories), each of which can be viewed on ebay.

These lathes are all what are known as 8mm WW lathes. The WW stands for Webster/Whitcomb the names of the two men that are credited with the development of the miniature watchmakers/jewelers lathe. The 8mm stands for the diameter of the mandrel that fits into and screws into the headstock. The 3-jaw chuck or collet unscrews from the headstock. Other accessories, for example a Jacobs chuck, can also be screwed into the headstock. Collets are made for a variety of applications, but are most often used for holding the object being worked on. Here are typical 8mm collets. The lower picture shows a collet mounted in the headstock and a rod being held by it.

Note that the collet has a (nearly) fixed hole size so that a set of collets is required. Collets are indeed convenient, but an entire set is expensive (check ebay for 8mm collets). A 3-jaw chuck obviates the need for a set of collets.

Here is a Duofold cap mounted in a jeweler lathe using a 3-jaw chuck. This particular picture illustrates an easy to polish the cap or, especially, the cap bands.

Note that in the picture of the cap being "chucked up" in a 3-jaw chuck the cap is screwed onto a portion of a barrel that has shortened to hold the cap. Such a device is called, in machine shop vernacular, a "jig." Most jigs are made from spare parts that are expendable (read: junk).


Here is a picture of a section chucked up in a lathe. The portion of the section that is outside the barrel is being shortened in order to make the cap screw onto the barrel further than it did previously. Note that a cross slide holding a lathe tool is being used here. It is not necessary to use this, but highly desirable. This configuration can also be used to reduce the diameter of the part of the section that slides into the barrel in case you are afraid it will crack the barrel upon reinsertion.


Here are pictures of a Duofold barrel and a cap chucked up in a lathe for polishing. The cross slide is not required for this operation and has been removed as has been the tool rest. The jigs that hold these parts were made from a junk Duofold barrel and cap (both jade), blind cap and clip retaining cap. The tailstock is used to keep the barrel and the cap from wobbling when turning.


There are two types of tailstocks that are used in jeweler lathes. The collet holding tailstock is as its name describes. It is capable of holding the same collets that fit the headstock. The non-collet holding tailstock has a laterally moveable "runner" that aligns with the center of the headstock. The center of the runner is often used to steady the work to keep it from wobbling when turning. The collet holding tailstock is much more versatile. For example, inserting a collet of the corresponding size permits it to hold an ordinary drill. To use it to steady the work and keep it from wobbling a special centering collet is used as shown in the picture below. A significant disadvantage of the collet holding tailstock is the cost. They are very expensive. The price is often comparable with that of a complete lathe. The collet holding tailstock is not a necessary accessory for work with fountain pens.
