Thank you for the comments. I do not have the ability to make a video. You can find a number of videos on YouTube for both the inside out and the twist method of turning. I used a Dremel tool to do the twist pen. I don't think the twist pen will be practical for a carry pen - the barrel is weak with so much material removed. It does make a nice desk pen - my brother wanted something no else had so this is what I came. up with.
