Great job on the tutorial Harry. One thing that I have found is that SHARP tools are a necessity when turning acrylic blanks.
I have used Gorilla Glue (original) for gluing the tubes into the blank, more time to fool around putting the tubes in. It does require overnight to set up though.
As to James' inquiry to CA as a finish, works great on all types of wood. I usually put on 4-5 coats of medium CA glue. Nice durable finish. There IS a learning curve though!
Keep on turning, the pens look great.
