By George I think he's got it!!!!!!!! Brian, great job, I love the pen. What did you end up using Lucite or an acrylic? I love the demonstrator types just as nuch as your other styles of pens. The Lucite swirl gave the best of both worlds, but I'm diggin the 100% clear.
There is no drilling on the final pass. A drill leaves a horrible surface.
I use a special boring bar that is very long, thin, and rigid.
From there all tools are homemade.
A long and skinny mandrel for mounting sandpaper, and a long skinny mandrel with a custom made tiny buff.
Thanks.
