I'm not sure what I'm looking at Billy but it looks impressive none the less.

Ed;
The heavy aluminum piece in the chuck is the fixture. It is made with that much mass to absorb vibration while cutting the thin casting. The casting is on a spigot and bolted in the center. This fixture will allow me to bore the offset holes for both distributors. and any other mill work. Then back into the lathe for final cuts.
