Hey Dave it wasnt difficult at all (well a bit more difficult than standard materials, but not bad). I use carbide and just make sure they are sharp. Some small bubbles that needed to be filled but you cant even tell they are there. hope that helps
That is a Definate WOW Pen, Michael.
The Blank is Outstanding, the details of the Banksia seed Pod are so Pronounced.
Your Finish is Terrific.
Fantastic work,
Brian.
