Overview of the nozzle transforms into a lawn mower grinder

Today I would like to introduce you to the attractive at first glance, the invention made their own handsWhich can come in handy almost each summer resident. (How it works I will show at the end)

The author of this homemade video blogger Mr SunY, some of his inventions have come to us to review and gained quite a large number of points, but it will be this time?

Today, we have to review nozzle with the help of which our Bulgarian turns into a lawn mowerSurprises? Let's take a look!

Idea

Rating 0 of 5

The video clip of the author, where he makes the nozzle their own handsI came across about a year ago. Then I decided to do a review on it, as this cap, seemed not quite unambiguous. And here's why.

The idea of ​​the invention is to make an eternal attachment for trimming grass on the principle of the trimmer. That is a kind of fishing line is rotating at high speed and cuts the grass.

In his invention with plastic fishing line, which, as time and is used in classical trimmers, the author suggests to use a steel bicycle cable.

Justifying this by saying that it will not break and will be eternal, it can not be said about a standard fishing line, which had to constantly buy more.

Probably in time of the nozzle their own hands the author has not thought about the safety of those people who can benefit from his advice.

As use a metal cable instead of a plastic fishing line, I highly do not recommendI think you understand why, and what kind of damage it can cause to your health.

Therefore, for the idea, I have to put 0 points, as it were, an interesting hack did not seem at first glance.

Design

Grade 5 of 5

Let us examine the structure, without taking into account the items described in the first paragraph, and concentrate only on the design and the good will of the author really invent practically eternal trimmer.

Then I design seems excellent and can help out many truckers who have not at hand or trimer lawn mower for trimming grass.

The author makes of the metal profile handle, the end of which is fixed grinders. In the grinder ring already fixed for holding the disc, in which two holes are made in the metal push cable.

This design, I like it, and looks not quite normal. From myself I would add on / off button on the handle, so that every time not to bend before rotating at high speed on a fishing line grinder.

For blogger design can be put 5 points, it seems quite rational for the declared functional.

P.S. I forgot even advise to make case for protection on the grinder.

Unfortunately, as I could see Mr SunY inventor does not like to give color to their work. This attachment is no exception.

For our part, I would have painted the ring and handle grinders, such as green, so the work would look more successful, in my opinion.

Evaluate the Bulgarian housing in this paragraph, we, unfortunately, can not, because this is not a work of the author. Therefore, for an item Design forced to put 0 points.

analogs

Evaluation 3 of 5

The basic idea, in my opinion is not to make Bulgarian lawn trimmer, namely to use a metal cable instead of a plastic scaffold for lawn mowers.

Such analogs, fortunately, found it was not, of the reasons we have already said in the first part of this review.

If we evaluate the uniqueness, and to put the ball, for the discovery of the author, then the score will be 3 points.

Total

Summarizing, we can say that the idea at first glance seems an attractive, even I wanted to implement it in their country, but if you think about the effect of the creation of such a nozzle their own hands, There may be more negative than positive.

The present invention obtains 8 of 20 points.
