    Owning a small Sherline lathe I've taken to turning a 17 tapered
    cone (the angle on my bezel punch set) the desired height and outside
    diameter of the proposed finished bezel, casting it up then doing the
    punch process. You can achieve a bezel of any shape & height with
    uniform wall thickness from top to bottom. For squares and triangles
    one or two annealings are in order. 

    When turning the cone I bur out the interior with a 17 cone bur you
    can purchase from Borel & Frei Jewelry Supply but a regular cone bur
    works fine. You can adjust the depth of the interior by grinding off
    the end of the bur to whatever depth you're cutting. You will need to
    pre-drill a center hole to the appropriate depth to compensate for
    the blunt cone bur. Then I straight turn about 10mm beyond the bottom
    diameter of the cone which serves both as a sprue point and an inline
    "dowel" to pop it back in the lathe after casting where I'll do a
    quick finish cut before the punching. 

    A little more time consuming than the more spontaneous artist might
    hope for but I get great bezels.
