Hi Joel
Kerry is correct about Bill getting info in Europe, but Rockhill Will, did post a lot of info on CAD and water jet to make bucks. I saw the bucks and remember that they fit together very well.
The bucks were to be used for the Bugatti project that Jim Henry is building. Not sure of the best way to search for them.
I found this in the automotive projects
