I have always just tied on my whiskers. No reason to use a bow press or anything else. There's a ton of videos on Youtube showing how to tie them on. I like to tie them on in the smaller ball version. Maybe not quite as effective, but it looks alot nicer. It seemed to quiet my bow down plenty using the smaller version.
