Me? Not even close. But why don't you just wire EDM it or don't you have the contour of the finished gear?

Occupant: any idea what clamping tools to use in EDM, the major dia is 168 and minor dia is 160?

If it's not an elliptical gear - the low a/b ratio seems to indicate that - then there should be a center mounting hole with a dowel hole next to it in the direction of the longer axis to line the pre-machined outer contour with the EDM code und the part can be clamped through the center hole.
