I'm installing a single rod in my one piece neck. I have a hole in both ends, headstock adjust. I put a nut in the heel end, inserted the rod and started tightening the nut in the headstock end, to try how it fitted before I put in the skunk strip. Ehen the nut started tightening, the rod started turning... How do you keep the rod from turning if you're not using a barrel nut in the heel end? Will the skunk strip hold the rod in place so it won't turn, or do I need to anchor it? What should I do?
