Thanks for all of the nice comments and questions.
Don....I'm still working on the design for the base. Don't know yet what I'm going to do. Hope to have it done by SWAT as this will be part of my display for the closed end session.
Thewoodturner.....I didn't use a kit. It is made with only a small piece of 7mm tube, a nib, and the ink cartridge.
Corry.....The E.I. Rosewood is very dark but there is a bit of dark brown grain to it. It is not entirely black, a very dark dark brown is closer to the color. Sorry the picture didn't show the grain but it is very subtle.
Steve and Travis.....The ink supply is very easy to change. The inside of the tube was reamed out just enough to allow the nib to be pushed on by hand but yet with enough friction to hold it securely in place. It can then be removed with not too much force to replace the ink supply. I will leave the inside design up to your imagination for now.
