For sale, my Contempo Lapidary 2 head sphere machine, I have the big Covington sphere machine, so I don't need this anymore. Included are 2 types of shaft adapters - 5/8-11 for the commercially available diamond cups, and the 1/2" NPT pipe threads that were supplied with the machine. Also several pipe thread plastic cups that I used for the finer grits are included. The adjustable water drip works fine. NO shipping, it's too big and heavy, pick up in Prineville, Oregon. I'm asking $400 cash payment when picking up. Thanks for looking. This is being cross posted on another Facebook site.
