Essential Materials and Tools


  • 2×4 Lumber Pieces: You'll need two pieces, each cut to a length of 16 inches. This forms the primary structure for the can crusher. Opt for a good quality, sturdy wood to ensure durability.
  • Metal Hinge: This allows for the pivoting action of the crusher. Ensure it's robust and rust-resistant.
  • L-Brackets: Two small L-brackets are required. They will help reinforce the structure and add stability.
  • Screws: A variety of sizes might be needed, depending on the thickness of the wood and the size of the hinge and L-brackets. Ensure they are rust-proof, especially if the can crusher will be used outdoors or in damp areas.
  • Jar Lid: This should be roughly the size of a standard soda can. It will act as the base against which the can will be crushed. It's beneficial if it's made of a strong, durable material.
  • Long Handle: Something akin to a broomstick or a sturdy wooden dowel. This becomes the lever, giving you the necessary leverage to crush the can efficiently.


  • Screwdriver or Power Drill: A power drill will make the process quicker and ensure a tight fit for screws. However, a manual screwdriver can also work if you don't have a drill on hand.
  • Saw: If your lumber isn't pre-cut to the required length, you'll need a saw to cut it down to size. A handsaw can do the job, but a power saw will provide a cleaner cut.
  • Sandpaper: Various grits might be useful. Start with a coarser grit for initial smoothing and move to a finer grit for finishing touches. Sanding the wood prevents splinters and gives a more polished look.
  • Tape Measure: Essential for ensuring accurate measurements. This will help in aligning the hinge, L-brackets, and ensuring uniformity in the overall build.
  • Pencil: Useful for marking measurements or drawing guidelines on the wood before cutting or drilling.

Step-by-Step Guide to Building a DIY Can Crusher

Step 1: Preparing the Base

  • Start by laying one of the 2×4 lumber pieces flat on a sturdy work surface. This piece will serve as the foundational base for your can crusher.
  • Use sandpaper to smooth out the entire surface, focusing especially on the edges and corners. Start with a coarser grit and move to a finer one to achieve a smooth finish. This step ensures that the wood is free from splinters, making it safer to handle and more aesthetically pleasing.

Step 2: Attaching the Crusher

  • Take the other 2×4 lumber piece and center the jar lid on it. The position of the jar lid is crucial as it determines the crushing point of the device.
  • Once you've centered the lid, mark its position with a pencil.
  • Secure the jar lid firmly onto the lumber using rust-proof screws, ensuring that it's flush with the wood. This way, when a can is placed on top of the jar lid, it receives a consistent and uniform crush each time.

Step 3: Attaching the Handle

  • On the 2×4 piece with the jar lid (the crusher piece), decide the best placement for the handle. It should be positioned so that when you press down, it directly exerts force onto the jar lid.
  • Mark the handle's position with a pencil.
  • Using screws, securely attach the long handle to the top of the crusher piece. The handle provides the necessary leverage, making the can-crushing process more efficient and less strenuous.

Step 4: Assembling the Device

  • On the base 2×4 (from Step 1), decide where you want the pivot point and attach one side of the metal hinge using screws.
  • Take the crusher 2×4 (from Steps 2 and 3) and align it with the base 2×4, ensuring that the jar lid faces downwards.
  • Attach the other side of the hinge to the bottom of the crusher piece. The crusher piece should now pivot freely, moving up and down with ease.

Step 5: Stabilizing the Crusher

  • To ensure stability and safety during operation, it's essential to prevent the crusher from shifting or moving.
  • Attach the L-brackets at the corners of the base 2×4, anchoring them with screws. This gives the can crusher additional stability, ensuring it remains stationary when crushing cans.

Once you've followed these steps, you'll have a functional DIY can crusher. Always ensure to test it out with empty cans first and make any necessary adjustments for optimal performance. Safety is paramount; always use the device with caution and keep it out of reach of children.
