I have a pen I finished last night that I have to deliver to a customer tomorrow. It is a Baron/Navigator. In testing all the functions of the pen last night, I found that when I screw the front section into the pen body with a refill in place, the threads make a horrible screeching sound. If you're not familiar with the Baron, this is a metal-to-metal connection. I have not had this problem in the past, but I need to figure it out ASAP. Any suggestions?
