Using the Shell feature and its not quite working...

I have had to teach myself how to use SolidWorks AND I am horrible at describing things so bear with me...

I am making tooling that is basically a cylinder with eight waves going from end to end.

My problem is that each wave is supposed to have .0625 wide and deep "lip"(?) around the edge.

I was able to partially achieve this by using the shell command (typing .0625 in the parameters section and clicking on

a wave then typing 1.0125 in the Multi-thickness Settings and selecting the inside of the cylinder).

It won't let me do one at a time and it won't let me do them all at once either. I can do all but one or only one.

There has got to be a better way. Who even knows if the waves got there in the "right" way.

Anyway...

I have included the part file so please have at...

Seriously appreciated.
