Alan,
Hey, if that's what they want, you did well in giving it to them. I am amazed that you could do the marble. What did you turn it with? A friend gave me some home brew PR that looks pretty good, so I guess I'll be experimenting with that soon. Some day, I may work my way up to stone. I was looking for something to make CBs with, but didn't find anything. I probably would have destroyed my carbide tools with it anyway.
BTW, I love the marble pen part. I hope your customer doesn't drop it.
Rob
