Mechanical claw V1.0.

Picture of Mechanical claw V1.0.
Hey all, this is my first concept of a manual mechanical claw that a person could use...
It uses a somewhat strange principle and I'm aware of the changes that improve functionality...
There isn't a prototype yet, but once I get enough funds to buy 4 bike breaks.
Anyways this is just for the community of Instructables.
Any ideas are welcomed.
Criticism is welcomed also! :)

I'd really love to see what you think about this, and I've got a feeling its going to work just the way I have imagined it.

And now with the explanation!

First of we've got a block (wooden, metal) that is the base of the claw. On it is found a handle with a lever for using the claw.
The claw is consisted of two metal handles that are placed on the base block. They are held together by screws and I've still got to work out this part so any help is quite welcome. The main principle is the squeeze that is produced by the breaks when the cables are pulled by the lever on the handle. That's it!

Hope you like it!

Hi... Many people have built items like this that are much simpler, and use only one cable to operate the claw mechanism. You can even buy a simple "grabber" that is used to help elderly people get things off of high shelves for about 20 USD.

You might try to find your brake assemblies from old bikes at a junk yard. A lot cheaper than buying brand new brake systems just to rip apart.

Also, if you want to use four brake cables, why don't you try and build a mechanical hand with fingers? You can adapt your idea to some that are already present on Instructables.

Not to be too critical, but your drawing, albeit very cleanly drawn, doesn't really show how this claw works... Keep it up though! I'd love to see how this works out for you!
