1. A method of manufacturing a stator of a cage for a continuously variable transmission (CVT), the method comprising the steps of:

  • cutting a plurality of radial grooves into a disc, the radial grooves angularly spaced apart about a central axis, wherein the radial grooves are formed to receive ball axles of the CVT;

    cutting a plurality of concave surfaces into the disc;

    cutting a plurality of cutouts from the disc to reduce the weight of the stator;

    forming a circular outer perimeter on the disc;

    cutting holes in a radially outward portion of the disc, said holes configured to receive ends of a plurality of stator spacers; and

    cutting a central bore in the disc, said central bore configured to facilitate the mounting of the stator about a longitudinal axis of the CVT.
