I'm trying to thread the 2" Nosepiece into the FW8G adapter plate. I get about 1 turn and the the threads start to bind. If feels like they are different threads, but both parts came with my Aluma 8300 / FW8G order. See attached picture. I've taken the adapter off the FW8G and checked the adapter and nosepiece for possible burrs or other reasons for binding, but both are in good shape. I even tried a light lubricant, but no difference in threading. I received the Aluma 8300 / FW8G setup in August last year.
