Knucklehead project started May 2007,

Thanks to Knukkel at Oldskoolchoppers.nl
I was able to borrow a knucklehead engine for a while!
I will take it apart, measure and model all the parts in CAD,
and then put it back together again...

This 4 pics below are renderings (with POVray) of
the CAD model made with Pro/Engineer Wildfire 3.0
