Turned this a couple of days ago. Two points to the person that IDs the "icicle". I thought it was a great re-purpose but then I am prejudice.
Stats:
Material = Ball is curly maple, upper and lower are walnut but I believe they might be different species of walnut. The top is much darker. It was a block labeled "black walnut" that I received from John K.
Height = ~8" (I forgot to measure it)
Diameter = ~2"
Finish = Rattle can poly high gloss.
