I thought I would try to make a pipe just to see if I could. I made these two and yes I smoked them. Had a few challenges with the stem and getting the holes lined up in the bowl. No turning on these. Just cutting and shaping. I don't have a lathe.
The stems were split and a small groove routed in them, steamed, bent around a jig, clamped and glued back together with a weed-eater string in the groove to keep it open. I pulled it out after the stem dried. Sorry about not having photos. I always forget to take pictures.
I also carved the wooden bowl in the photo using a power carver bit on a hand grinder.
