It is a solid piece of wood with 2 connecting holes strategically drilled to meet at the right spot.
Buffed with the 3 stage system Tripoli, White diamond and carnauba wax and completed with my food grade wax.
The inside of bowl is lightly rubbed with a honey/water 1:1 mix and let sit for 24 hours, then re-peat for a longer lasting pipe.

After you find a suitable blank for your pipe. It needs to be mounted on the chuck at one (the bowl end) and lightly tightened with the tail-stock on the other end.
In my case I had to put it between centers to make a tenon that fit the inside jaws of my chuck.
Step 2: Round the blank
Rough turn it close to what you want the finished diameter of the bowl to be, and then thin out the stem end of the pipe. I am bad for not measuring while turning, I eyeball dimensions and use a fibonacci gauge all the time for projects. So, I'm sorry about not having dimensions for you. To me, this is the best part about turning (stop when it looks good) ;)
Basically, turn the stem to the correct shape you want and remove your tail-stock so you can square up. Then flatten the stem opening.
