How do I model this branch thing? I used a weldment profile for the horizontal branch, but i need to model vertical stubs that are conical in shape. Is there a way to use a weldment profile for this conical feature? Ideally, i'd like to be able to use the trim/extend feature so that it will match the diameter of the horizontal tube just right. Unless you guys know a different way to achieve the same thing. 

Below is the stub/nub
