I haven't done this myself but to me a good solution would seem like creating small brushes and gradually rotating them horizontally by a small amount (5?) and increasing their height by an even smaller amount (1? 2?) and placing them near each other in a circle formation around a central cylinder, while cutting off the choppy edges of the small spiral ramp brushes. Wow, that was a lot of words. I need to go have a drink.
You smell bad, eiii. Like a dog took a crap on your face.
