My current project is making candlesticks out of Texas red
agate. The desired length of the agate portion is about 7" long,
0.750 in diamater.
Too slender to do by a core drill, too difficult to get this
symmetrical and evenly ground by hand.
So, before I glom together a lathe to attach to my diamond
grinding wheel, making what the machinists would call an "outside
diameter (OD) grinder) for lapidary materials. I thought I would
ask the group if anyone has done this before, or if there even is
a commercially available machine that I can buy, rather than
I don’'t mind building my own, but it always takes 4 times as

6th Eugene Oregon - (541) 687-8100. He produced a multi-axis
lapidary lathe capable of preforming shapes like chess pieces. As
I recall it was fairly reasonably priced as well. I think
Contempo also produced a rock lathe called the “Sculpture” -
