Some basic help with spline paths

I am triing to work with a spline path, I think this is the right direction but may not be, to create a bent wire spring drawing. Here is what im trying to do I have a spring wire that goes out straight for 1 inch then bends back at 30 degrees and comes back over its self. Looks like the edge of a 30 degree draftsmans angle but instead of the sharp point it is curved down at the point of the angle. The wire is 0.020 inches in diameter. I drew the initial path I wanted as a set of lines that are connected. How do I get the circle that is the wire diameter to follow this during an extrude? Thank you for the help with this.
