How do you mate a sphere in a conical cavity?

Assembly consists of 1 conical cavity and 1 ball.
How do you mate them so that the ball is tangent inside the conical cavity?
See public document 'sphere in conical seat'

Thank you,
Paul

    I must have answered myself with a blank answer, but this question is still unanswered.

    Got a work-around:
    ball:create a mate connector on sphere centre
    seat: sketch circle of ball diameter tangent to cone-create mate connector on that circle centre
    mate the 2 connectors by fastener.

    however, this method only works for 1 ball diameter, not for any size.

    I was able to get a ball to sit down in a cone by combining a tangent mate and slider mate, and the ball stays in place if its diameter changes.

    I doing that on the example, it does not seem to work.
    Thanks.

    Here is the hydrostatic bearing. I used connector mates to assemble both sphere and cup to the conical seat.
    If anybody can find another way using different types of mates, I'd like to know.
    Thanks.

    Neil,

    Thanks. Still requires to create the extra mate connector on the sphere ( I guess we cannot avoid this), but better.

    Shouldn't need to, you could use the mate connector from the origin of the sphere or if you hover over the sphere one should appear.
