How to make a wooden piggy bank with a locking lid

Creating a wooden piggy bank with a locking lid is a fun and rewarding woodworking project. Below is a step-by-step guide on how to build one, including materials, tools, and the process involved.

Materials Needed

1. Wooden boards (preferably pine or oak) for the main body, base, lid, and locking mechanism
2. Wood glue
3. Screws or nails
4. Hinges (small, suitable for a locking lid)
5. Small lock and key (optional, but ideal for creating a locking feature)
6. Sandpaper (fine-grit for smoothing edges)
7. Wood finish or paint (optional for finishing)
8. Measuring tape and ruler
9. Saw (table saw, circular saw, or miter saw)
10. Drill and bits (for holes for screws or lock mechanism)
11. Clamps (for securing parts while gluing)

Step 1: Plan and Measure

Start by deciding the size of your piggy bank. A typical size could be around 6 inches in height, 4 inches in width, and 4 inches in depth.

1. Base: Cut a square or rectangular piece for the base.
2. Sides: Measure and cut four side panels (two for the longer sides and two for the shorter ones).
3. Top Lid: Cut a piece that matches the top dimension of the box (slightly larger than the top of the sides).
4. Lock Mechanism: You’ll need to create space for the lock on the lid, and it will need to align with the body of the box.

Step 2: Cutting the Pieces

Using a saw, cut the following pieces:

• Base: A square or rectangular piece of wood for the bottom.
• Sides: Four pieces of wood for the four walls of the piggy bank.
• Lid: A piece of wood slightly larger than the top to fit securely over the walls.
• Slot for Coins: Cut a small rectangular slot on one side of the box where the coins will go in. Ensure the slot is wide enough for coins to slide through easily but narrow enough to prevent larger objects from being inserted.

Step 3: Assemble the Sides

Now that you have all your pieces, begin assembling the walls of the piggy bank:

1. Glue and Clamp: Apply wood glue along the edges of the side pieces and attach them to the base. Use clamps to hold everything together until the glue dries.
2. Screw or Nail the Sides: Once the glue is dry, reinforce the joint with screws or nails along the edges to ensure stability.

Step 4: Attaching the Hinges

Once the main body of the piggy bank is assembled, focus on the lid:

1. Position the Hinges: Attach two small hinges to one edge of the lid and the corresponding edge of the box. Use screws to secure the hinges in place.
2. Test the Lid: Open and close the lid to ensure it moves smoothly.

Step 5: Installing the Lock Mechanism

To add a locking feature to your piggy bank:

1. Drill Holes for the Lock: Choose where you’d like the lock to go, typically on the front of the lid. Drill holes for the lock’s latch and corresponding clasp.
2. Install the Lock: Attach the lock to the lid and ensure it aligns with the base. If using a key lock, insert the lock’s key mechanism and test it.

Step 6: Sanding and Finishing

After assembling the piggy bank and ensuring that everything fits well, it’s time to finish the project:

1. Smooth the Edges: Sand all the edges and corners of the wooden pieces to prevent any sharp or rough spots. Use fine-grit sandpaper for a smooth surface.
2. Apply a Finish: If desired, apply a wood finish to seal the wood and give it a polished look. You can use a wood stain for a rich color or leave it natural for a rustic appearance.

Step 7: Final Touches

• Decorate: If you want to personalize the piggy bank, you can paint it, add decals, or carve a design on the lid or sides.
• Insert Coins: Once everything is complete, you can insert coins through the slot on the side of the box. Close the locking lid to secure them inside.

Tips for Success

• Pre-drill Holes for Screws: If you’re using screws, always pre-drill the holes to avoid splitting the wood.
• Lock Placement: Make sure the lock is easy to operate while still being secure enough to keep the contents safe.
• Measure Twice, Cut Once: Always double-check your measurements before cutting to avoid mistakes.

Conclusion

With these steps, you will have successfully made your own wooden piggy bank with a locking lid. It’s a functional, secure, and customizable piece that’s perfect for saving coins or even as a gift. Enjoy your woodworking project!
