Project started December 2020, Real version here 20 March 2021 I added Wheels and fork, the rear wheel is the one I will actually be using, the front forks and wheel are ones I have lying around in my shed, but not necesarily what I will be using. I might try some long narrow forks, or a springer or girder next time. That is one of the advantages of building in CAD first, I can try various combinations without buying the parts! 26 February 2021: The frame with all the castings is now completely in CAD, and I have put the rear hub and brake assembly in place, centering the hub in the frame. I also added the 4-speed transmission. Next I will add the chain and rear wheel and see if I can get it all to line up nicely! 8 February 2021: The front half of the frame (from a 1974 Shovelhead) has now been laserscanned and then CAD modeled. The hardtail part only scanned sofar. Modeling all the castings takes a lot of time! I can already see that I will need to do some modifications in the seat area.... The CAD model of the neck casting is now for sale at www.dbbpshop.com 9 January 2021: 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 the 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.
