How to Make a Beer Can Crusher

Updated April 17, 2017

As the earth's resources continue to diminish, recycling has become an important part of everyday life. Many forms of household rubbish, including metals, paper, glass and aluminium can be successfully recycled into new, usable products. Putting aside objects for recycling, however, can take up valuable space, especially in smaller homes. Homemade can crushers go some way to solving this problem by flattening beer and soda cans into a fraction of their original size.

Lay down a wooden board on a work bench or other flat surface. Drill holes for hinges three inches from the base of the board at the centre of the wood. Attach a strap hinge to the holes in the wood using a screwdriver and screws.

Drill holes in the second length of wood three inches from the base. Attach the second piece of wood to the strap hinge you fitted to the first piece using screws and screwdriver. The two segments of wood should now lay directly on top of one another, with the top end being able to open and shut against the second.

Attach one jar lid to each piece of wood using wood glue. Fit the jar lids at the ends opposite to where the hinge was fitted. Position each jar lid about two inches from the tip of the wood and on the inner side, so that the flat sides touch when you push down and the mechanism shuts.

Attach a door handle to the top piece of wood. Attach the handle at the opposite end of the wood to where you fitted the hinge and on the reverse side to the jar lids. Handles from screen doors work best and they can usually be attached using a screwdriver and screws. The handle makes the can crusher easier to use as it provides an easy grip, allowing force to be generated when crushing.

Position an aluminium can in the area between the jar lids. Grip the door handle. Pull it upwards and force the crusher down, flattening the can in the process.
