So, I want to start using my Nemesis again. I haven't used it about 2 months, it has been sitting in my vape gear tackle box. My problem is the bottom assembly. when I try to adjust the bottom assembly I only loosen the button, not the whole assembly. The problem is the inner adjustment screw is "cleaner" and unscrews much easier than the bottom assembly. How do I clean and grease the lower assembly to allow it to make adjustments without having to disassemble the whole thing and use tools to get the lower piece out of the tube? I have petroleum jelly to lube the threads, but it's still sticking.
