Drawing an abstract curve

My team this year is considering a helical hopper/ball movement mechanism. I am in charge of CADing this up. I am trying to figure out a way to project the helix onto a 2D plane to help manufacture it. Using a formula, I have figured out that the outer and inner diameter of one revolution of the helix is 83.0 inches and 31.8 inches. The width of the track I am using is 8 inches. I am wondering how, if it's even possible, I can draw this up in Inventor. I think the finished product should end up like this:



Could any of the resident CAD gurus help me out with this one? Like, provide instructions so that I could replicate the results. Thanks!
