Mike, I agree with all of Mr. Redburn's comments. The wood pens look good and with a few layers of CA finish, the overturning would disappear, leaving a perfect result. Don't try to improve the pens unless you can take them apart as he suggested with the punches. Gentle taps work better than a bigger hammer. Disassembly is a skill we have all had to master and it builds your confidence. I think there are some articles in the library on general disassembly techniques. If you are confused on a particular style, try a search and If you don't find the answer, post a question.
To get a beautiful finish on plastic or wood, stop the lathe after each grit and sand longways. This takes out the rotary scratches and levels the surface from end to end, removing any ridges from turning. All the next grit has to do is remove the previous longways scratches, so it doesn't take much sanding to do that - then follow with the lathe off sanding at that grit - repeat. Your final step with 12,000 micromesh will leave almost microscopic scratches longways on the pen. Visually, if there is any light scatter, it will be in parallel with natural reflections and the shine lines on the pen and add to the effect of a perfect finish.
