DIY puzzle box supplies for one secret compartment

Who this list is for

This supply list is for hobbyists planning to build a single wooden puzzle box with a hidden sliding compartment. It’s tailored for those comfortable with hand tools and small woodworking projects, not for those looking to buy a finished puzzle box or use power tools.

How to use this list

Begin by laying out your four 1/8 inch basswood craft sheets and six basswood strips on a self-healing cutting mat. Use a steel ruler and pencil to mark your cuts. Cut carefully with a craft knife fitted with a fresh blade. Assemble the box with wood glue and hold pieces in place using eight spring clamps. Shape and finish the compartment’s edges using fine sandpaper and a set of small needle files. Once the box is assembled and dry, apply wood stain, then finish with clear wax using cotton rags. Masking tape helps hold tricky joints while glue sets.

Common mistakes

Don’t rush the glue drying time—impatience leads to weak joints. Avoid using dull craft knife blades; they cause splintering. Some skip sanding or filing, which makes the secret compartment stick. Don’t forget to test the sliding mechanism before final gluing. Staining before assembly can cause uneven coloring at the joints.

What is on this list

You’ll need: four basswood craft sheets (1/8 inch), six basswood strips, craft knife with fresh blades, self-healing cutting mat, steel ruler, pencil, wood glue, eight spring clamps, eight sheets fine sandpaper, small needle files, small bottle wood stain, tin of clear wax finish, three cotton rags, and a roll of masking tape. Mark off what you already own to avoid duplicates.

After the build

Let the finished box cure overnight after waxing. Test the secret compartment’s movement a final time. Wipe down any dust or residue. Store leftover stain, wax, and sandpaper for your next project. Clean your tools and clear your workspace so you’re ready for another build.
