Instructions: Developing a parabolic trough frame

1 Assess and label two boards to dimensions of 1 inch by 1 inch by 2 ft. Then minimize the boards utilizing a table saw.
2 Draw a collection along the bottom borders of 1 board, utilizing a material rectangular, and label the collection at every single inch. This will be utilized to plot a parabolic curve on the board.
3 Locate the middle label on the u pipe solar collector you just drew. Beginning with the collection to the suitable of the middle, use the rectangular to make labels at these lengths: you should know 1/8 inch; 1/2 inch; 1 2/16 inch; 2 inches; 3 2/16 inches; 4 1/2 inches; 6 2/16 inches; 8 inches. Mark the collections to the left of the middle collection in the identical pattern. Connect the dots with your pencil, utilizing an arcing movement. This will give you a parabolic shaped trough.
4 Cut along the curve utilizing a saber saw.
5 Center the minimize item of wooden on the next board. Trace the curve. Then minimize out the trough from the next board. The two d-shaped items will be utilized to assistance the aluminum trough. The corner items of minimize wooden can be discarded for this assignment.
6 Assess 2 inches right down from the middle of the crest of every single board. This is the focal stage of the trough. Drill a hole at this stage on every single item, utilizing a 1/2-inch drill tad.
Assembling the collector

7 Cut an item of aluminum flashing (obtained in the roofing division of most developing provide shops) to a sizing of 2 feet by 4 inches. This will be wrapped close to the two wooden trough frames.
8 Assess and label a corner of the aluminum flashing 1/2 inch in from every single borders. Punch a hole via the aluminum at this stage with a hammer and finishing toenail.
9 Spot a wooden trough frame on its borders with the curve facing upward. Turn the aluminum so the shiniest part is facing right down. Then place the corner of the aluminum on the borders of the frame so the edges are flush. Spot a drywall screw into the hole in the aluminum, and then screw the aluminum to the wooden frame.
10 Punch an additional hole via the aluminum, 1/2 inch from the borders, 3 inches from the earliest hole. Then screw the aluminum to the curved borders of the trough utilizing this hole. Carry on in this method, every 3 inches, till the aluminum is entirely connected to the wooden frame.
