I have a couple of those blanks. I was curious what a kitless made with them would look like. Now I know. That is really sharp. Did you paint the inside after drilling? I would have thought it would be more transparent. I know you can't hide the cap threads on that material because they're so close to the surface, but what about the rest of it?
Very nice.
From a learning standpoint I really appreciate it when you post the pen completely taken apart.
