Problem Trimming Knurl

 From:  propmaster (PWWHDR70)

I can't seem to find a way to do this.



I'm trying to trim the knurled cylinder using the curved surfaces. I just need the knurled area within those surfaces, not the rest of the cylinder.

I tried making the knurled cylinder a solid tube and using boolean. That didn't work either.

Maybe I'm going about it the wrong way. But I've tried everything I know. Any clue as to how to get the desired effect?

I tried to attach the file, but it's rather large and is encountering problems during the upload. Still, any ideas?
