Set a kitchen timer for a set amount of time.Use a permanent marker with a fine tip to draw a small line on the float stick, just above the bottom eyelet screw, and a matching line on the wood stick.Before you can use your water clock to tell time, you need to calibrate the stick so that you can use it to gauge the passage of time.
They should not hold the float stick perfectly still.Ĭalibrate the clock. The dowel you use will need to fit into the eyelet screws comfortably and without much friction or tension.These eyelet screws will secure the float stick in a vertical position, thereby reducing the amount of bobbing the stick will do and making it easier to accurately read the water clock once it is assembled.Remove the nail and screw the eyelets into both holes. Hammer a nail into the marks, only sticking it in for one-quarter of its length.The two eyelet screws should be screwed into these two measured marks.Make a mark on the center line 1 inch (2.5 cm) below the top of the float stick. Place the float stick inside the container, near the same side as the stake.Make a pencil mark on the center line of the stake 1 inch (2.5 cm) above the top edge of the lower container. The bottom of the stake should be even with the bottom of the container. Place the wood stake next to the bottom container.The center will be at about 3/8 inch (9.5 mm). Mark the center of the wood stake using a ruler and pencil.Screw two eyelet screws into the stake at even intervals, roughly one-third the distance in from either end. Use a hacksaw to cut a wooden stake down to a length of 2 feet (60.96 cm).
