Issue with screw that came with thread guide
I am playing with my 301A and was trying to put on the thread guide. The screw that came with the guide does not seem to fit the holes. It appears too big and won't screw in. I also tried the same thread guide on my FW and it would not work either. Aren't they suppose to be interchangeable and why won't it work...other than the obvious that the screw is too large???
Also I saw a photo where a red felt thread "thingy" (don't you just love my technical term?) was used with the screw and thread guide. Is this just to protect the finish or does it serve a vital purpose???
TIA for help!!
