I thought I'd try making a few corncob pipes.
This is Model 1. The bowl is about 2 inches deep, 3/8" across. Stem is about 6-1/2 inches long, made from a piece of cane I cut a few days ago.
It still needs a little work, like a way to seal the stem in the bowl with something that won't poison the smoker.
Model 2 will for sure have a 5/8" wide bowl. I may try a bent stem as well.
