Pipe Making

Pipe making is the handcraft in which every stage of a pipe, from the rough block to the finished product, is carried out by a single person. In a factory the work is divided among many stations, each tied to its own machine; this arrangement is described in the how a pipe is made entry. At workshop scale, every decision — from which grain in the block will stand out to the diameter of the airway — falls to the same person. The craft has no written curriculum; knowledge builds up largely through trial and error and through practical solutions makers pass on to one another.

Block and Stem Material

The briar burl used for the body (stummel) is dug up between thirty and sixty years of age; details are in the briar entry. Two different cuts come out of a burl. "Ebauchon" blocks, cut from the interior, are more plentiful and cheaper, but are considered more likely to contain a crack or void inside. "Plateaux" blocks, cut from the outer surface, are considered superior in grain pattern and are the preference of most craftsmen.

The stem, meanwhile, is worked from rod-form material. Of the two common options, ebonite is a hard rubber obtained by long vulcanization of natural rubber with sulfur and linseed oil; its sulfur content ranges from 25 to 80 percent. Ultraviolet light oxidizes the surface over time, after which free sulfur bonds with moisture to form sulfate and sulfuric acid; the surface gradually shifts from grayish green to brown. Acrylic does not show this degradation. The two are compared in the stem materials entry.

The Body's Internal Dimensions

Turning the block into a pipe depends on opening three separate holes: the chamber where the tobacco burns, the draught hole that carries smoke along the shank, and the mortise where the stem sits. Their placement in the pipe is shown in the pipe anatomy entry. The measurements cited in workshop circles are not a binding standard but a debated range: roughly 16-25 mm for chamber diameter, 3.2-4.3 mm for the draught hole, and 6-9.5 mm for the mortise, with figures around 8 mm considered customary for the mortise. The airway's effect on smoking is debated constantly among makers; alongside diameter, keeping the cross-sectional volume constant along the shank is also considered decisive.

At what stage the holes are drilled varies from workshop to workshop. The common approach is to drill the holes while the block is still rough and build the shape around those axes. The reverse is also practiced: when the body is shaped first and the holes drilled afterward, the line where the grain looks best and the flaws are minimized can be chosen — but since there's no margin for correction left, a single wrongly drilled hole ruins the block. This second approach is said to be preferred in circles around the Danish school.

Stem and Tenon

Ready-molded stems come in a limited number of shapes and sizes; they need to be filed down before fitting to the shank, and heated and bent for curved bodies. In hand-cut work, the stem is shaped from rod material starting from scratch, specifically for that one body; with the mold constraint removed, body and stem become part of the same design.

The tenon connecting the stem to the shank is either turned from the stem's own material or glued on as a separate piece. In the second approach, a widely used material is the acetal resin (polyoxymethylene, POM) marketed by DuPont as Delrin. Its coefficient of friction is low, it's wear-resistant, and its dimensional stability is high; it can withstand continuous use up to 80 °C. Its self-lubricating surface allows the stem to be removed and reinserted frequently. Its very sturdiness also has a downside: if the pipe is dropped, the shank is more likely to break than the tenon, and shank repair is far more difficult than stem repair.

Getting Started with a Pipe Kit

Because drilling mistakes can't be undone, most beginners start out with ready-made sets — a "pipe kit" — whose body is already drilled and stem roughly fitted. In these sets, what's left to the maker is shaping, sanding, and polishing. Kits are prepared separately for straight, bent, and freehand bodies; the stem connection can be flush or military-mount.

The equipment needed to finish a kit is modest: a variable-speed hand drill, a flexible sanding disc, files in various cuts, a coping saw for rough shaping, buffing wheels, and carnauba wax. Because wood dust irritates the airways, safety glasses and a dust mask are considered mandatory. Once work moves to drilling the block itself, the list expands to include a drill press or lathe, chamber bits, and fine drill bits for the airway.
