Project started December 2020,

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.
