Steve, I see more success than attempt here. Back in 2006 I bought a FP & RB set in Paua and wanted to duplicate it... with a difference. I had already been casting, but didn't really want to do the strips in resin thing. So I bought a few shells and ground some into pieces from 1 to 3 mm and cast them suspended in black resin. THAT was an attempt. A dismal failure as well. Why? Because the stuff was so hard, I couldn't turn it on a wood lathe. There was no abundance of carbide tipped tools back then (still don't have one), and that might have helped. But that is how we learn. And my hat goes off to you and everyone else that has made pens showing this beautiful material!
