Good thinking, Andy! All I did for mine was create a cross section of the shape of the rim, then revolve it on the Y axis. For the tuning rod holes I just created one from a cylinder, used the boolian to make a hole and then repeated it around the rim. The whole rim is actually different to this; I've gone for a cast design, as opposed to rolled, as this design is, which made it much easier to make.

Doesn't look as nice, but it is a whole lot easier, lol!
