Universal self-locking wrench

Hello dear readers and the inhabitants of our site!
In this article, the author of YouTube channel "Be Creative" will tell you how he made a universal self-locking wrench.

Materials
- Old wrench
- Bolt and nut M8.

Instruments, used by the author.
- Bulgarian
- Screwdriver
- Cutting disc
- Cleanup disk
- Vise, file
- Marker.

Manufacturing process.
So, the first thing the master clamps the old wrench in a vice, and cuts off the head of the wrench.




Then he makes a longitudinal incision along one edge of the workpiece.



The resulting groove is processed by a file.



At the end of the second part of the key, a notch is made.


Then grinds part of the handle material to the groove thickness.




Inserts a handle into the head, applies marking, and drills a hole for the M8 bolt.




Then it collects the received parts together.





That is the principle of operation of such a mechanism.



With a standard hex head, the key copes perfectly.



There was also no problem turning the round-head pulley.



And the wing nut also loosens easily!


Thanks to the author for an interesting version of the wrench!

Good luck to everyone, good mood and interesting homemade goods!
