Thats a fine first Dave, looks like it would fit snug in my hand if I had it!
Speaking of finish, a method I use that works amazing, you may want to check out. Its not expensive either!
Get a firm buffing wheel, and some white tripoli compound (in a bar). After you have sanded thru all your grits, mount the wheel on a drill or roto tool depending on the size wheel you get.
Spin the wheel, and apply some tripoli to the edge of the wheel. Then apply the wheel with moderate pressure to the pen wood while it is spinning. The trick here is to make sure your buffing wheel is turning the opposite direction of your spinning pen blank.
You will see the finish transform before your eyes. Do that as much as you want until happy. It will polish a surface on your wood that is so fine it is slippery in your fingers. Follow up after this with spray laquer (deft), again while it is spinning. Just a blast of one or two seconds.
Let it spin dry, only takes a few seconds. Stop and check it to see if its dry, and if so, spin it up and spray it again. From that point on, you can use whatever you like, but I apply all the finishes to my bowls and urns while they are mounted because spray applications go on ultra smooth and the spinning dries it evenly.
I usually put 3 coats of deft sealer, then steel wool it with fine, then 3 coats of spray poly steel wooling in between coats if necessary.
You will not believe the glass like appearance of your turned work using this method.
