My crown action feels “rough”, what does this mean?

A rough crown action is typically caused by extra residue on the case tube. This rough feeling should quickly loosen up with wear.

A couple of easy (but sort of weird) solutions to this issue:

1. Use dental floss to "clear" the threads of the case tube.
2. Rub a pencil on the case tube - the graphite is actually like a lubricant for the threads.
