Skull piston carving part 4

Dr Benway over on the JJ posted this skull piston offering on The Friday art show thread

Cheers to Dr Benway for letting me post it here and share the fruit of his labour. Here is explaination of his technique :

                " Panhead piston built up with TIG.

                 Drill big holes.

                 Finish with round files,sanding drum,whatever you've got!"

What you've got is another fine example of carved skull piston art
