Helix sweep slanting problem

Hi everyone,

 

I am trying to create an auger with a triangular fin.  The fin has to stay normal to the axis.  When I try to create a sweep of the fin, the profile tilts as it moves along the spiral.  I cannot get rid of this tilt that is produced with the sweeping feature. The final aim is to produce a variable pitched auger that is used for mixing of a powder. 

 

Can anybody please help me to understand why this is happening and how I can get rid of it.

 

Attached is the picture of the problem.  I've added the part as well.

 

Thanks in advance!
