How to Make a Hollow Interior Door

Making a hollow interior door requires some woodworking skills and tools, but it's a project you can accomplish yourself with careful planning and execution. Here's a general guide on how to make a hollow interior door:

Materials and Tools:

- Plywood (at least 1/2 inch thick)

- 1x2 or 1x3 lumber for framing

- Wood glue

- Clamps

- Circular saw or table saw

- Drill and drill bits

- Sander

- Door hinges

- Door handle and latch

- Wood screws

Steps:

1. Measure and Cut the Plywood:

- Determine the desired size of your door based on the door frame you have or want to install.

- Cut two pieces of plywood to match the door's dimensions.

2. Frame the Plywood:

- Cut the 1x2 or 1x3 lumber into four pieces that are slightly shorter than the height and width of the plywood pieces.

- Attach the framing lumber to one of the plywood pieces using wood glue and clamps, forming a rectangular frame around the edges.

- Allow the glue to dry completely.

3. Join the Plywood Pieces:

- Apply a bead of wood glue along the edges of the framed plywood.

- Place the second piece of plywood on top, aligning it with the edges of the frame.

- Clamp the plywood pieces together and allow the glue to dry.

4. Reinforce the Corners:

- Cut two triangular pieces of wood slightly larger than the corners of the door.

- Attach these corner reinforcements inside the door frame using wood glue and screws.

5. Hollow Out the Door:

- Using a circular saw or table saw, cut a series of vertical grooves about 2 inches apart on the inside of the door.

- Start cutting about 2 inches from the top and bottom edges of the door and continue until you reach the opposite edge.

- Be careful not to cut all the way through the door.

6. Smooth the Surface:

- Use a sander to smooth out any rough edges or imperfections on the surface of the door.

7. Install Door Hinges:

- Mark the locations for the door hinges on the door and the door frame.

- Drill pilot holes and then attach the door hinges using screws.

8. Install Door Handle and Latch:

- Mark the location for the door handle and latch on the door.

- Drill holes and install the door handle and latch according to the manufacturer's instructions.

9. Finish the Door:

- Apply a wood stain, varnish, or paint of your choice to protect and enhance the appearance of the door.

- Allow the finish to dry according to the product's instructions.

10. Install the Door:

- Fit the door into the door frame and check that it opens and closes smoothly.

- Secure the door to the frame with screws or nails, ensuring it's level and aligned properly.

Remember that safety is crucial when working with tools and materials. Wear appropriate safety gear and take precautions to avoid injuries.
