Step 1Smoothen the edges of the two wooden boards with sandpaper.

|
Step 2
Print and cut out with a pair of scissors the two diagrams from the downloadable model (section blueprints/plans)rectangles from the downloadable model.
Using white glue and a brush, paste them on the two wooden boards.

|
Step 3
Position the two boards one against each other as shown in the picture and stick them together by creating a hinge with thick adhesive tape.
 |
Stick the tape only when the two boards are on top of each other (sundial closed), otherwise it will be impossible to close the sundial. |

|
Step 4With the help of a drill (3 mm bit ), make a hole in the larger board where all the lines meet on the drawing.

|
Step 5Close the boards against each other and make a hole in the second board exactly at the same place than the first hole.

|
Step 6
Cut a piece of string of about 20 centimeters
Tie a knot at one end and pass the string through the two holes
Then tie a knot on the other side so that the two plates are standing at a 90° angle when the string is stretched.

|
Step 7
Using the glue gun, paste the small compass on the circle drawn on the larger board.
 |
Check if the compass is glued in the right direction and that when the board is positioned on a flat surface the needle turns freely. |
