Thanks Michael and Edgar!
Edgar - yes - a bit time consuming (prolonged labor and delivery) - but she was worth it.
The PVC-pipe-cast blanks in the lower left of the picture were less labored - just filled the molds with random hexagons (which remind me of the venerable jujube candies that stuck my teeth together through Sat. AM double feature horror movies or westerns double features costing 50 cents in the good old days - but don't eat these hexagonal jujubes) + PR, and I expect some interesting little rascals to come off the lathe.
