Is this what you’re after?
Assuming so, here show I would proceed:
Something I’ve figured out this last couple weeks is to use the 3D rough pass and the first finish pass for the field as well as the model. When you use a very fine stepover for that first finish pass the field is very uniform versus doing it as a separate pocketing operation.
You may want to adjust some of the parameters I’ve used. Say, make your base 0.50" high versus 0.75" so that your leaf lies deeper and can be covered with more epoxy. You would then adjust the rim and leaf height accordingly.
I didn’t include any bit recommendations, all my bits are specified in metric. Although I like my freedom, I avoid “freedom units”!
