Does anyone know if this guy has a web site? The pictures show an outstanding level of craftsmanship. I'd love to see some work-in-progress shots with context!
He has uploaded a ton of photos to a Picasa web album. It looks like CNC was used, quite a bit:
Picasa Web Albums - Christian - Hodgson Radia...
Another resource for builders of Hodgson's radials (Ageless Engines) is this site... the owner has created CAD models of most of the components. Some very nice work.
