Modeling the Panhead motor here
30 July 2021
Well, as you all know by now, I bought a 1960 Panhead engine
so I am busy putting that in CAD for this project. I made a
separate page where you can follow that. The Shovelhead in
this project has been replaced with the half finished Panhead
so that I can start figuring out the alignment of the primary belt.
Also I did not like the lines of the seat area in this frame so I am
going to modify the frame so it will look like it does in these
renderings. The Primo primary belt has also been added.

There hasn't been a lot of time for my own projects lately
but I managed to put a shovel engine in here and a rear
chain. I also added a wavebar and Cole Foster grips, so the
virtual bike is now more or less the same as the real one.

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.
