I turned a 6 inch long piece of maple to about 1 1/2 inch diameter (need to be smaller than the pendants and used double stick carpet tape to attach the wood. I then put the tail-stock up against it with a small piece of sammy cloth, I then round it and cut the dome up to the tail-stock. then pull the tail-stock back and used 80 grit sandpaper to finish the dome, then finish sanded to 600 grit.
