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...


Last week the knuckle cylinder head had 132 features, this week I added 124 features and completed the cast iron part.
The reason I am showing this is to make the point that there is no quick and easy way of doing this, it is mostly a matter of determination really... On the positive side, mirroring the front cylinder head to make the rear head took less than a minute. I will have to check the angle of the rear exhaust port though, because sometimes the exhaust flanges are not angled the same front and rear.


Total time spent sofar 52 hours.
