I like being kept on my toes. Was feeling good just to have spelled "Plumber" right with no spell check on here anymore.
As far as bees wax on the threads I find that in hot weather it does not work as well as the tape. However, too much tape and you may have problems getting the screws with small allen heads out later. It also works well to true up broadheads if they do not spin correctly. Screw machines can not make a crooked broadhead ferrule. So if alignment is not right it is usually a fit issue between the ferrule and the insert or insert and the shaft. If your problem is with the ferrule to insert fit the tape will correct it quickly. And, your broadheads or field points won't rattle loose. It will also make sure your broadheads never get locked up in the insert. More people cut themselves trying to get stuck broadheads out of an arrow/insert than installing them.
Remember - Hold the broadhead and turn the shaft! Never the other way around.
