How to make an array of cutouts in SolidWorks along a helical path 

The essence of the question: "Hello Peter!
Help please advice how to create a place in the body for mounting the knives? If you do squeezing it all okay, but if the opposite cutout is an error in the position relative to the coil. I sent two files, one of which you will see the error of orientation along a spiral line.
Regards, Alexey"
