The front half of the frame is from a 1974 Shovelhead, I
started with laserscanning and then CAD modeling the neck casting.
For scanning I use an Einscan Pro Plus 2X mounted on a tripod
for more stability. All the postprocessing and CAD modeling
was done with PTC CREO Parametric 7.0
From the workshop manual I have a blueprint of the stock frame,
which I am also using for reference. Tubes are easy in CAD but
tthe castings are quite complicated because of the more organic
shapes
I have finished the hub and drumbrake, this will help me
figure out how to get that tire in there while keeping the wheel
centered; I really don't like offset rims.
