Original lure development project starts #3

Hello!

This is Kamimura from Hitotoki Works.

This season I've been spending a lot of time developing lures.

Or rather, it would be more accurate to say that it's taking so long because it's our first attempt and creating an action that has never been done before isn't going as well as we had imagined... lol

On to the fourth test

Once cutting is complete, we head to the site.

The work was carried out while checking underwater video so that movements underwater could be easily observed, not just from a human perspective.

The action has become even more powerful with more lateral sliding movements, making it flawless.

Even anglers who were unable to perform the same type of twitching that my wife did, which involves subtly creating line slack and flicking the lure, were able to produce a similar action.

Move to a river with water

After testing for about an hour, we noticed that the lure tended to float up easily and fell slowly in places with a bit more water, so we suddenly moved for an hour and a half to the Junai River, where there is more water.

As expected, the results revealed the vague issues I had noticed, such as the lure floating up easily and its slow fall speed.

In areas with a lot of water and depth, it was not possible to explore near the bottom.

This was the result of consulting with Mr. Sasaki, who helps me develop lures.

Changing the center of gravity .

It seems that I was mistaken in thinking that a heavier lure would have a faster fall speed or be less likely to float up...

In order to increase the fall speed, etc., the center of gravity position, which is determined by the balance between the air chamber and the weight room, is important.

It's nearly impossible to expand the weight room given the current body shape.

▼ Conventional two-room structure

As a result, we decided to combine the two-room weight room into one room and redesign it to lower the center of gravity without changing the weight of the weights.

The design was redesigned using CAD to create a one-room structure.

The single-room structure has lowered the center of gravity compared to the conventional two-room structure.

This slight difference in the center of gravity.

The weight doesn't change, but the fall speed changes dramatically.

The weight of the lure does not affect the fall speed or range!

A 4.5g lure can sometimes fall faster than a 5g lure.

In fact, many people don't even know about the builders who make handmade lures.

It would be great if the current action could give us the power to keep the fall speed range one level lower.

At the time, I had no idea that even a slight change in the center of gravity would have a hugely negative effect on the action...

To be continued...
