THE SCIENCE BEHIND MAKING YOUR OWN CRANKBAIT LIPS

Compiled (from the posts from the “Tacklemaking.com” forum) and written by Gene Graham (Lincoya)

Hopefully, the following information can help ALL crankbait makers.
We will start with the mechanics of how crankbait lips work and finish by explaining how to make your own.


Crankbait Lips
All diving lures have a lip or flat surface that protrudes out from the front of the lure at different angles, depending on the type of lure. When retrieved, the lip makes the water flow over the top of the lure, thus creating the diving effect. Different hydrodynamic pressures occur on either side of the lure body, so it swings one way making the water pressure on the other side lower, thus forcing it to swing back. The lure now shows the wobble that represents a swimming fish. This wobbling action will vary according to the size of the lip and shape of the body.

A crankbait's tracking speed, running depth, wiggle, and profile are all affected by the size and shape of the lip, where the line tie is located, and at what angle the lip is connected to the body. Typically a lip is not selected based solely on body design; rather it is selected with a desired action or depth in mind.

The swimming action of a lure is very important. This action is determined by the size of the lip and body shape. Remember minnows should generally have a tight wiggle and wobblers a slow and wide wiggle. The tighter lure actions are generally designed for quicker lure retrieves while shorter or fatter lures like slow to moderate retrieves, and swim with a wide slow wobble.


Was looking at some old threads today and saw this. This guy is amazing. He has an encyclopedia for a brain. Fascinated at the differernt things metal lips can do.
