Knucklehead project started May 2007,

Thanks to Knukkel at
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 modeled the lower tins that cover the rockers. The intake and exhaust covers are not the same, not only are the intake covers morrored and shorter, a lot of dimensions are slightly different too. Each cover has about 65 features, I modeled 2 of 'em and mirrored the others. I also modeled rockershafts and valveguides. Time spent this week 14 hours.


Total time spent sofar 66 hours.
