Instructions
Testing Chamber
Determine the size of the test chamber. The chamber will be made of plexiglass, with the fan at one end and the wind sock at the other.
Measure the four sides of the rectangular testing chamber on the plexiglass and cut them using the saw or razor blade. A good razor blade can be used to cut thin plexiglass, while a saw will be needed for thicker plexiglass.
Super glue the four plexiglass sides together to form a rectangle. The open front and back must be square and the sides must meet at 90-degree angles.
Blower
Measure four trapezoid shapes on the plexiglass. One piece will span from the bottom fan's output horizontally to the bottom of the testing chamber. Another piece will span from the top of the fan's output upward at an angle to the top of the testing chamber. The angle of the two sides of the top and bottom should all be equal. The two remaining pieces will fit on each side to form a truncated pyramid.
Cut out the four pieces of plexiglass.
Super glue the fan side of the bottom piece to the bottom edge of the fan's output.
Super glue the two side pieces to the bottom piece and the fan output.
Super glue the top piece to the side pieces and the fan output.
Measure the height of the bottom plexiglass trapezoid. At 1/2 the height, measure the distance from one side to the other. Repeat this for all four sides. The lengths will be the dimensions of the first air diffuser.
Add 1/2 inch to each dimension of the rectangle and cut the diffuser out of the steel mesh screen. Cut a 45-degree angle into each corner to allow for the sides to be folded over, creating a little tray.
Place super glue around the sides of the mesh tray and slide it into the pyramid attached to the fan. When it goes in all the way, press the sides against the inside of the pyramid. The steel mesh should be perpendicular to the airflow coming out of the fan.
Measure the outside edge of the open section of the pyramid. Cut these dimensions out of the mesh screen for the second air diffuser.
Cut 1/2 inch into each corner of the second diffuser at a 45-degree angle. Fold the edges inward to form a tray, as you did with the first diffuser.
Place super glue around the edges of the tray, and place the diffuser into the open end of the pyramid. It should sit about 1/2 inch inside the opening and be parallel to the first diffuser.
Wait 24 hours for the super glue to dry completely.
Putting the Parts Together
Slide the blower and the testing chamber together so there are no air leaks between them.
Open the piano hinge and place one side against the side of the testing chamber and the other side of the hinge against the blower pyramid.
Super glue the piano hinge in place.
Super glue the cabinet latch to the opposite side of the piano hinge with one part of the latch on the testing chamber and the other part on the blower pyramid.
Super glue the wind sock onto the open end of the testing chamber. This works to diffuse the airflow coming out of the chamber. It is not necessary, but it reduces some of the noise.
