Modelling problem - key on shaft

Hi!

I have a problem with modeling a special key on a shaft. I need to create a key that has constant wide (6 mm) and constant deep (4 mm) everywhere on diameter. (attachment 3)

I tried two methods of modeling:
1) method - wide of the key is not constant (attachment 1)
2) method - deep of the key is not constant and radii are not tangent (attachment 2)

I will be grateful if someone help me to find the best way of modeling this key.

If I'm not mistaken, that specific application would require you to be able to sweep a 3d solid and that is not current functionality in Creo, although Creo 5 is supposed to have a 3d helical sweep.

I've had some success in generating 2d sections for a sweep along a helix in Creo 3. So far I've tried a cylinder and wedge and compared the results of the surfaces generated by sweeping a 2d section and creating a boundary blend to the surfaces generated by patterning 3D cut along a helix.
