Spline Multiple Helices?

I am trying to figure out a way to sketch multiple helices in multiple planes and connect them to make a single helix for a swept cut. I may have been able to create this with a single Helix if it wasn't for several of these helices having origin points outside of (00,00). I will give a few of the dimensions so you have a better idea of what it is I am trying to do.


Start with a sketch of a circle on the front plane, dia. 4.226" extruded boss 6". The helix will be sketched on the top of that boss, clockwise rotation. Below is a simple table laying out the first 4 helices required.


Radius          Rev.          X position          Y position          Height

1.157            0-180°          0                         0                    0

1.157          180-225°         0                         0                 .319

1.656          225-360°       .415                    .287               .957

1.890          360-540°         0                         0                 1.459


This should be enough information, but if anything else is required, please let me know.


Thanks in advance,
