Elderberry (Sambucus sp.) is a fantastic tree to make pipes from. (It also has edible flowers, berries, and many other uses). It’s easy to make pipes from elderberry because it’s inner pith (the central tissue of a large woody stem) is very soft and spongy. To make a pipe, the California Indians would ram the pith of sections of elderberry sticks with sharpened, fire-hardened sticks of a hard wood such as mountain mahogany (Cercocarpus betuloides). Such simple tubes of elderberry were packed with tobacco and smoked, or formed the stem of a pipe having a bowl of stone or clay.
I have not read of any Indians making pipes like mine above. I cut sticks in sections just behind a right angle bend, and on the other side of the fork, left room for the pipe stem. So after I formed a tube from the main length, I carved out a bowl from the nub of the fork, and carefully connected the bottom of the bowl to the tube with a thin tube I drilled perpendicular to the first tube. I used a long flathead screwdriver that I sharpened at the tip for the initial drilling, then cleaned out the tubes with a round bastard file. I stained the pipes with linseed oil to protect them. The staining really brings out the beautiful patterns left on the inner bark by bark beetles.
I used only dead, downed wood, so there was no need to dry or season the wood, nor cut any live tissue. The species in the SF Bay Area is Sambucus nigra ssp. caerulea. The first few uses, I smoked plentiful material and didn’t inhale, in order to “cure” the bowl; leaving it thoroughly burnt inside so future smokes don’t have me inhaling elderberry wood smoke. (The pic shows them freshly cut; after curing the bowls are charred black).
I have been using such pipes for smoking herbal blends for years and prefer them (for functionality) any other I’ve ever owned. I’ve made about six of all sizes. They each took about 30 minutes total work time.
