I found the site when surfing on Google for pen blanks. Be sure and show us a picture of the pens turned from Lignum Vitae. I understand that it is real heavy and does not float. Let me know how it turns and polishes. From what I read about it, it is extremely hard to glue due to the oil in the wood. Have you given any thought what type of glue you are going to use?
Best of Luck.
