Copying, Rotating etc.

I'm new to Solidworks so please bear with me.

I'm in the middle of drawing a camshaft. I've drawn the main part of the shaft & added one of the cam lobes. I now want to copy the lobe along the shaft 7 times & then I need to rotate them around the shaft at varying degrees. I did manage to do a linear pattern but then couldn't rotate the lobes individually.
