    The drawing seems to show two cylinders joined by a cone, not just a cone.
    Yes Aluminium. Really 1mm?
    Yes sorry I should have said 2 cylinders and a cone.

Does the outside have to taper as well as the inside? for example, could you have a tapered bore but the outside being a cylinder of od larger than 30mm but a shoulder on the end where the bore is smallest down to whatever the smallest od of your cylinder is? Would easier is you didn't have to machine the outside to a taper as well. The tapered bore would be a doddle in a CNC lathe.
    Yes two cylinders connected with a cone.

    Taper only needs to be OD for looks.
    Ideally the larder ID end would also be round over but I guess that is going to be harder/costly?
    Would a chamfer be okay?
