While making pipes can be very satisfying, especially when you get to smoke one of your own pipes, shaping by eye can be at the least, a hard venture.
Getting everything even using that method takes a lot of practice and even then can be difficult for a new guy.
Keep up the great work and I'll keep watching as you progress, as I love watching the progression of a budding pipe maker.
A couple tips........ work a bit more on your shank to stem fit, as a cleaner and smoother fit and look there is preferred. You may also want to clean up the stem a bit more also with some sand paper. I start with about 400 grit and work my way up finishing with 1000 grit wet/dry and sand using it with water. Gives a very smooth look before finally finishing with a buffing wheel and white diamond buffing compound.
