Need some filleting help

The image below is a x-section of my copper elbow. I may beridiculous but I want the OD of the bend to be the same as the IDof the collar. This creates a multi-body part with what looks to bea zero-thickness zone where the bend and collar should meet. Isthere any way to create a fillet that can join these two bodies andmake them a single body in the process? I've tried all of thefillet options but couldn't get any to work the way I want. I maywell be using the options incorrectly.

Thanks in advance.
