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...
Finally
completed the rear head and started working on the tin parts
that cover the rockers. Ofcourse these are also different on
the rear head than on the front, so just mirroring did not work...
This week spent 10 hours.
