I bought the block, I drilled it I carved it. Whats wrong cant be seen from this angle. I drilled the shank about 3mm off center, thus the shank is off to one side of the bowl. Also, due to mistakes in the shank the stem fit isnt perfect.
I've done the same thing on one of my pipes, It's still one of my best smokers.
Slow down, contemplate all your drilling angles, take your time setting up and drilling.
All become a learning experience , better pipes will come from this.
