Creating a door handle cup in a car door

I have created my door panel and need to make the concave cup that goes behind the door handle. I thought revolving a matching elipse and doing a boolean subtract would do it but that did not work either. The EggTubeThing.3dm has what I want but the tutorial does not cover how they were made.


Thanks for any suggestions.
