DIY universal wrench

Good time to all. Today in this article we will consider how the author made one useful tool called a universal wrench. According to the author, he did not invent anything new, he simply made his own model.

And so he first made a key model (which will consist of two parts) on cardboard in a 1: 1 scale.

Then he transferred everything to metal. As a material, the author used two pieces from springs 14 mm and 8 mm thick. Detail No. 1 the author made from a piece of 14 mm



and part number 2 of 8 mm.


Then, using a conventional angle grinder, I cut out the details.

And he removed all the unevenness with a file.

Then he made a hole.

Then the author made a slot in the part number one at the junction. The slot width is one third of the thickness of the part itself.

Then he made notches on the parts using a angle grinder and a file. These notches will serve for strong adhesion of the key to the working part bolt, nut, etc.




The second part at the junction with the first

The author first heated and tapped on the crimp.





Then he brought to the desired size using angle grinders and also made a hole

The author also made notches on this detail.

Then he turned a small tooth for the spring.

On the first part he also made a tooth.

And set about assembling

To connect, the author took a metal rivet

and the puck

He put on a spring.

Checked.

And riveted through the puck.

This is how the author’s finished key looks like.

And at the end of everything done, the author proceeded to test the key. The size of the grip of this wrench is from 14 to 32. As the author says with this key, you can also turn the plumbing couplings and square nuts.

For some simple housework, it’s very convenient ...Somehow, an improved analogue of an adjustable (and, somewhere, a pipe) wrench.
