Center the blade on the hub so that it is concentric when it turns. Place the knife top up to the coulter blade so the knife and coulter blade just slightly contact each other at the tip. Then, as the coulter blade rotates up the knife, you want to have a gradual gap between the knife and coulter blade. Also, the knife needs to be centered side to side on the coulter blade.
