Simple automatic hook for rebar tie their own hands

I have not often work with fittings, but once all the same it was necessary. A few years ago, I poured strip foundation for your new fence, and of course had to deal with the reinforcement.

I remember how it was necessary have the hell of a lot of trouble with the screed reinforcing rods, what I? Today we review on an instrument made by hand, which simplifies this operation several times. (How does this work will show at the end)

Idea

Grade 5 of 5

Honestly, after the times when I had to have the hell of a lot of trouble to tie reinforcement in the construction of strip foundation, the idea seems to me excellent.

Boring holes in the metal tube - the workpiece with their hands

Thanks to the author of the idea of knitting fittings simplified several times, there is no need to make additional turns by hand. Only once cost to hook the wire and pull over, and a reliable and sturdy unit is ready.

Definitely deserves the maximum evaluation of the idea. She decides to do a serious problem, and can help a lot of people during the construction.

Design

Evaluation 3 of 5

Turning to the assessment of the design is to say that he made a hook quite reliably, despite the fact that the author is using the materials at hand.

Author for making this tool with their own handsI chose a metal pipe and a drill - the basic elements of this design.

In the role of the hook serves to cut off the nut sector

Though tool I pretty much like all the same I am with some skepticism, to this mechanism.

In my opinion, it seems to me that such a design can have drawbacks. For example there may be formed as a consequence skewing and jamming of the drill in a metal tube.

At the site of the author, I would consider a more reliable way to twist mechanism.

Evaluation 4 of 5

In this implementation instrument their own handsIn the field of design, I am embarrassed not only painted metal tube, why not paint?

Also appreciating the design, I would have made a rubberized grip to tool He held fast in his hands and does not slip out during operation.

analogs

Evaluation 2 of 5

Analogs do exist, they are usually called - hook for tying rebar.

Minus of such products as compared to the author's tool, is that there is need to do a lot more movements for breeding rather than in the space provided in the survey instrument.

The cost of these plant hooks in the region of 100-200 rubles, which can compete with the development of the author. Since there are close and not expensive counterparts, the maximum score in this section can not put the author.

Total

Grade 14 20

Despite the small estimate, compared with our previous reviews, I can say that the tool has turned out quite decent. But is it worth doing it when there are analogues cost 100-200 rubles?
