How To Get "No Tap"

Every time I tune my balisong, there is tap. If I tighten too hard then the handles become stiff. Is there a better technique or tips and tricks to achieve better resilts?

Edit: I find that it's better to just tweak it in very small amounts. Still, if there's a better technique to getting results in faster times, let me know. I've seen squidindustries's videos on it and they seem to tune balisongs very quick.
