Auto-seams; like where the hood meets the qtr panel, or where the door meets the rocker panel. Etc Cetera. It was intentional. Its my pipe, I can do what I want, for example:
The draft hole is drilled as per sketch such that the bowl becomes more like the meerschaum cup in a calabash which draws from dead-center. This pipe smoked great, burbed perfectly even despite my sloppy packing technique, and stayed lit even when it seemed like all was lost. Just a gentle draw and presto, smoke.
I'm not trying to reinvent the wheel here but its all about learning, what works and doesn't work, and why. I also used this pipe to experiment with the black dress finish (try no. 5) and am satisfied with the results but not finished finishing this one yet. I am going to finish when (and if) my shop ever warms up. The carnuba wax should be easier to apply.
Goodnight Mr.s Calabash, where ever you are!
