After about 50 or so pens made using the mandrel, I took the jump to TBC. Here is my first one with the new method, I'm happy with the result. Black palm in a gun metal Sierra, CA finish.
And "Happy" you should be Sam,
A Beautiful Pen, Magnificent Blank, Superb Fit and Finish.
There is not much more one can ask for.
Congratulations,
Brian.
