Larry resumes drilling a geniculate bannerstone, he started in 2009. He glued a template to its surface and drilled for 33 minutes-15 seconds to get to the point where the template could be removed. For this experiment, Larry is using ax-making debitage for the grit. Larry hopes to use his experiences from previous bannerstone drillings to expedite this attempt.
