Terrific Pen Jason.
Excellent Olive Blank,
Beautifully Turned, and Nicely Finished.
You mentioned that you are having a problem separating the Blank from the Bushing due to the CA .
I suggest that you might like to get or make some of the Deldrin or HDPE Tapered Bushing with a 60 deg taper, and with the Hole to fit your Mandrel. Then when you have finished turning and sanding to your Diameter, take the Bushings out, and replace them with the Tapered Bushings, and then Put on your CA, it will not stick to the Tapered Bushings.
Well Done,
Brian
