Thanks @markyboy57 . I knew Dan personally. We enjoyed talking lapidary and beads. I purchased equipment from him years back. He will be missed by a lot of us.
Here is my flat lap setup that was a collaborative effort and some beads discussed.
He was the kind of person the world needs more of.
He freely shared his immense knowledge of lapidary, jewelry making and of course turquoise. We are lucky on this site to have many of the same ilk.
Here is a link to some of his work
