Thanks for the reply Lee. I have an angled pick, and tried that but the cap won’t budge. I wonder if the brass nut isn’t a lock. I’m going to see if I have a deep socket to loosen the nut. I’m heading to town today so will stop in Can. Tire and grab a set of those in the link. I don’t need them, but they look like they might come in handy sometime and they have two left.
