All I got to say is WOW!!
Thats a lot of work, looks great.
Do you resaw the quaters first? Also what kind of magnifing visors (optivisors) do you use? Back 20 + some odd years ago when I could still see I used to do a lot of small intricate die work for electronic components, and used an SPI product I think they were called Magna Visors then I had a triple loop mounted on the front of them to take the magnifaction (spelling?) down even more.
Takes a bit to get used to working like that, but I'm sure you know that. :wink:
Cant wait to see that in a pen blank. Great work.
