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
week I made the camcover, almost finished except for the ribs.
The gentle curve of the cover makes it pretty tricky to model.
Spent 6 hours on 99 features.
