Kevin,
Those are really nice, although I do like the shape of the bottom "icecicle" better on the first one. I decided last night to try to make a few of these. After destroying the first one trying to hollow it (btw, anytime the inner diameter excedes the outer diameter it really makes a mess), and then making the hole too large on the second one for the icecicle I had already made, I was finally successful on the third. But then my wife decided the woods I had used, bocote and maple, clashed with each other. Oh well . . .
