Step 1: Materials
2x2.45m 25mm aluminum angle stock
2x2.5m 25mm aluminum angle stock
8x0.39m 25mm aluminum angle stock
4x0.80m 25mm aluminum angle stock
2x0.85m 25mm aluminum angle stock
0.33mm 25mm wide flat aluminum bar
2x 0.39m by 0.85m aluminum sheet
100 pop rivets
3m copper tube
2x2.5m 50mm aluminum bar
2.4m x 1.2m 8mm aluminum sheet
Step 2: Preperation
Cut a 25mm square from both ends creating one side of 2.5m and one of 2.45m
Step 3: End Pieces
Clamp a 0.39m angle stock to each side of the sheet.
Drill a hole just bigger then the pop rivet at the top,bottom and evenly spaced on the angle stock.
Pop rivet the angle stock to the sheet
Do the same with the 0.80m but put them on the top and bottom and on each side.
Measure 11.8cm up from the 0.8m angle stock that forms the center of the bottom of the U and drill a hole big enough for the copper tube.
On the top angle drill a hole in the center (This will be for focusing so use a drill smaller then the copper pipe)
Follow the step again. Now you have your 2 end pieces.
Step 4: Middle Pieces
Step 5: Conncting the Pieces Together
(Making Angle Bracket)
Measure 25mm from both ends of the flat bar
Measure .191m from both ends and make the cuts from the 1st picture.
(Attach Angle Bracket and long piece)
Then take the 2.45m pieces and clamp them to a end piece. Then take the bar and make a bracket for support. (picture 2)
Attach the other end piece to the other end of the 2.45m piece without angle bracket
measure 0.8m from the end piece and attach the middle pieces
Place the 2.5m piece on the top of the middle and end pieces (Picture 3)
Step 6: Reflective Surface
Put the 2.4m x 1.2m sheet in and push them in under the bars(picture 2)
Stick the copper pipe through the hole.
Congratulations the trough is now done
Step 7: Aiming the Trough
Lookout for part 2 on how to automate the aiming and using it to do useful work.
