Brandon,
Here are shots showing 4 sides of the pen. When I glued the pieces together, I kept the grain oriented in the same direction. It probably doesn't show up in these pictures, but the end grain is slightly darker, and the opposing sides reflect more shine and depth. As far as the CA, i did not notice much difference between the end grain and the rest of the blank. One thing I did before turning was to apply a liberal coat of thin CA on all 4 sides. I figured I'd need the added support before trying to knock off the corners.
