The blank on this Black Ti and Copper Aero Twist is an Exotic Blank's "Electric Nebula Alumilite". The twelve copper pins were made from solid core wire and glued into the blank with thin CA glue after the holes were carefully located using the lathe's indexing wheel and drilled to the surface of the brass tube using the depth stop on my drill press. The four larger pins were made from 3/32" copper tubing filled with epoxy mixed with "True Blue" and "Macro Pearl" Pearl Ex powder pigments. The copper inlay was made from a 0.25" thick copper sheet. The blank with pins and inlay was turned with a carbide cutter and then finished using Micromesh pads to 12000 grit and polished with Meguiar's Plastx.
