Translate Cable along with a Rotating Cable Constraint Problems

Hello all, I am working on a assembly where a cable wrapped around a drum is animated to rotate with the drum, and there is a longer cable coming off of the rotating cable wrap, this longer piece goes down to another cable on a roller assembly. I have edited the assembly to work without the actual cable drum and without the roller assembly ( I wasnt allowed to share those models ) There are now two cylinders in place of the cable drum, a Grounded center to hold everything in place, a Rotating center which is animated so the wrap can rotate.

 

My problem is when the part named "Drum to Roller" is a lofted cable with angled ends to meet the "Drum wire wrap" at one end and it meets the "Radius cable ends" at the other end. I need the "Drum to roller" to stay constrained to the "radius cable ends" as well as the "drum wire wrap" ... and after being constrained still animate.

I have set up the animation and you will see that the "Drum wire wrap" is animated to keep the end vertical , the animation is set up to look like the "drum wire wrap' is un-raveling cable and the "drum to roller" is to be what un ravels.

 

I hope this is making sense, its kinda hard to explain. I need to find a way so that the "drum to roller" translates down and over , staying constrained to the "drum wire wrap".. You will see that so far it does not.

 

Anyone have any ideas?  I have heard of positional representation might do it, but I dont know how to do that.

 

I have attached two links below they include the two halfs of my assembly, place all the files in the same folder so you wont have to search for them manually.
