After I put the engine in CAD, there were still a lot more components to
measure up before I could actually start on the frame.

Harry wanted a HD 4-speed transmission in his bike (which I already had in
CAD), but Willem wanted a Triumph transmission. Because both will use the
same frame design I also had to make both transmissions fit on the same mounts.
