How to create a wooden filing tray with a stacking feature

Creating a wooden filing tray with a stacking feature is a great DIY project for woodworkers looking to add a functional and stylish element to their workspace. This project combines basic woodworking skills with a little creativity to design a tray that can hold and organize documents while also being stackable for added convenience.

Materials Needed:

  • Wood (choose a hardwood like oak, walnut, or maple for durability)
  • Wood Glue
  • Wood Screws or Nails
  • Sandpaper (120, 220 grit)
  • Wood Stain or Paint (optional)
  • Wood Finish or Sealer
  • Measuring Tape
  • Saw (table saw or circular saw)
  • Miter Saw (for precise angled cuts)
  • Drill and Drill Bits
  • Clamps
  • Wooden Dowels (for stacking mechanism)

Step 1: Design and Dimensions

First, decide on the dimensions for your filing tray. A common size for a standard filing tray is about 12 inches by 16 inches, with a height of about 3-4 inches. You’ll need to make allowances for the stacking mechanism, which we’ll discuss in the next steps.

Tray Dimensions:

  • Bottom: 12″ x 16″
  • Sides: 3″ high (adjust according to preference)
  • Front and Back Pieces: 3″ x 12″ (adjust for front opening width if desired)

Step 2: Cutting the Wood

Start by cutting all the necessary pieces for your tray:

  • 1 piece for the bottom (12″ x 16″)
  • 2 pieces for the sides (16″ x 3″)
  • 1 piece for the back (12″ x 3″)
  • 1 piece for the front (12″ x 3″)

Using a miter saw or table saw will give you clean, straight cuts. Make sure to measure and mark each cut carefully to ensure precision.

Step 3: Assembling the Tray

Now that you have all the pieces cut, it’s time to assemble the tray.

  1. Attach the Sides: Start by applying wood glue along the edges of the bottom piece. Position the side pieces along the edges of the bottom and clamp them in place. For added security, you can use wood screws or nails to reinforce the sides.

  2. Attach the Front and Back: Next, apply glue to the edges of the front and back pieces and attach them to the sides. Clamp them in place and ensure everything is square and aligned properly before allowing the glue to dry.

  3. Add Reinforcement: To add extra strength to the tray, consider adding small wooden dowels or screws at the joints where the sides meet the bottom. This will help prevent the tray from loosening over time.

Step 4: Creating the Stacking Feature

To ensure the trays can stack securely without slipping, you’ll need to add a simple interlocking mechanism. This is typically done by cutting small notches or grooves into the tray’s edges that allow one tray to “lock” into the other.

  1. Create Grooves for Stacking: Measure and mark a spot about 1 inch from the top edge of the back piece. Using a router or a small handsaw, carefully create a shallow groove that will allow the back piece of one tray to rest securely in the front of the other tray.

  2. Test Fit: Before attaching the groove permanently, test to make sure the trays stack properly and interlock without much wobbling. The groove should be just deep enough to allow the back piece of the second tray to fit snugly into it.

  3. Optional Dowels for Extra Security: Another option for securing the stacking feature is to drill small holes in the sides of the trays and insert wooden dowels that will allow one tray to rest on the dowels of the other.

Step 5: Sanding and Finishing

Once the tray is assembled, it’s time to smooth out the surface and edges. Start with a coarser sandpaper (120 grit) and gradually work your way up to a finer grit (220 grit). Sand all surfaces, including the corners, to ensure the tray has a smooth finish that’s comfortable to handle.

After sanding, wipe down the tray with a damp cloth to remove any dust. If you plan on staining or painting the tray, now is the time to apply your chosen finish. A wood stain will enhance the natural grain, while a paint finish can add a more personalized look.

Once the stain or paint has dried, apply a wood sealer or finish to protect the wood and ensure its longevity. This is especially important if the tray will be used frequently or exposed to moisture.

Step 6: Final Assembly and Testing

Once the finish has dried completely, assemble the trays and test the stacking feature. You should be able to stack multiple trays securely without them sliding apart. If you used dowels or grooves, ensure they fit well and that the trays stack without wobbling.

Optional Customization Ideas:

  • Label Slots: Add small wooden label slots to the front of each tray to help organize and identify the contents.
  • Handles: You could add small wooden handles to the sides of the tray for easier handling.
  • Decorative Elements: Consider adding decorative touches like wood inlays, carvings, or even a painted design to personalize the trays.

Conclusion

This simple yet effective wooden filing tray with a stacking feature will help you keep your workspace organized and efficient while adding a handcrafted touch. By following these steps, you can create a customized and durable filing solution that fits your specific needs.
