Clay, George has listed about all your possible problems with this pen. It is a great starting point. The wood itself is excellently turned. The surface is clean and smooth. My preference is not to use walnut in a pen. It is a lot like mahogony (sp) in that it makes beautiful furnature but some what boreing pens. there is not enough texture in either to show the beauty of the wood in small pieces. IMHO Keep up the good work, you are improving as you go along. This is just my openion and offered in the hope of improvment. Keep turning.
Charles
