I just finished a WC Classic American RB. The lower barrel screws into the upper barrel fine for the closed position, but the lower barrel finial will not post into the upper barrel in the open position. I tried another pen made from the same kit. It works fine. I then checked the OD on the finial of both pens. Both look identical at .345". I am seeing is what appears to be a little "mushrooming" where the finial is inserted into the black plastic coupling. I believe this is what is hanging up. Not much I can do about that, but can I open up the ID of the brass tube on the upper barrel to gain clearance? If so, what would be the best procedure?
