How to make a jar opener with screw caps

You often come across jars with Euro lids that are difficult to open with your hands. In this case, you have to use every possible means to get to the contents. Having made such an opener, you will be able to cope with even the tightest lid in 2 seconds.

Materials:

• 3/4 inch pipe;
  
• nuts and washers M12;
  
• M12 pin;
  
• strip 20x2 mm;
  
• wooden blank for the handle;
  
• rubber for linings.

Opener manufacturing process

It is necessary to make a blank from the pipe 320 mm long with a cutout 20 mm wide and 300 mm long. Its sides must be strictly parallel.

A strip flag is welded to the edge of the M12 nut. The width of it should slide freely inside the pipe slot. Its length is 30 mm. Next, 2 jaws are bent from the strip to grip the lid of the jar. One of them is welded to the flag on the nut.


The second stop must be welded to the pipe at the end of the cutout. Then the first jaw with a nut is inserted into the tube.

Nuts are welded into the ends of the pipe.

They must be drilled out to remove the threads.

Next, a long threaded rod is inserted and screwed through the sliding nut.

At the exit, behind the stationary jaw, a washer is welded to it.



Then a limit nut and a wooden handle are screwed onto the beginning of the stud. Rubber pads are glued to the jaws of the tool.


To use the opener, you need to separate its jaws by rotating the handle and place the lid between them.

Then the tool is clamped on it and turned counterclockwise. At the same time, you need to hold the bank. Thanks to the long lever, the lid opens without effort.
