  • CSI flat and phillips screw drivers

The Plan

In the prep lab
  1. Cut the 8'2x12s into two pieces: 5' and 7.5" (three pieces including the excess)
  2. Cut the 1x12 into two 29.5" pieces (three pieces including the excess)
  3. Cut the pipe and unistrut into 5' lengths and then file the sharp edges smooth
  4. Screw the 7.5" piece to the heavy 10" corner bracet. Place the brace 19 inches up from the bottom of the 5' 2x12.
  5. Place the actionpacker in the crook of the 2x12 L and screw it to the L with 1-1/2" wood screws and 1/8" fender washers... also predrill pilot holes for the wood screws so as to not split the skinny 2x12.
    1. 2 or 3 screws between 2x12x60 & actionpacker
    2. 1 screw between 2x12x7.5 & actionpacker
  6. screw the hinges to the 2x12 (again with 1-1/2 wood screws & 1/8" fender washers)
  7. screw the loose end of each hinge to the 2x12 for less floppiness during transport.
  8. bolt the unistrut angles to each unistrut leg -> 5/16" fender washer + 1/4" x 1" Hex Bolt + 1/4" Cone Nut
  9. Screw the clear tote to the 1x12 with fender washers
  10. screw the instrumentation inside the tote to the 1x12
  11. wire up the instrumentation
In the field at the site
  1. bolt the unistrut legs to the hinges -> Slots 2 & 4 from the end on the unistrut secure to two of the holes on the long axis of the hinge. -> 5/6" regular washer + 1/4" x 1" Hex Bolt + 1/4" Cone Nut
  2. bolt the unistrut cross-piece to the unistrut legs -> 5/16" fender washer + 1/4" x 1" Hex Bolt + 1/4" Cone Nut * 2 legs
  3. bolt the solar panel to the unistrut cross-piece -> 5/16" fender washer + 1/4" x 1" Hex Bolt + 1/4" Cone Nut * 2 pcs
  4. screw the unistrut angle to the 2x12x60 with fender washer, too
  5. Pound the anchor spikes / screed stakes to keep the tripod from tipping.
  6. pound another spike / screed stake below the end of the unistrut cross-piece where the AT/RH pipe will go. (Leave 4" out of the ground)
  7. place the at/rh pipe either over the spike or screed stake... or, hose clamp the pipe to the spike/screed stake.
  8. hoseclamp the at/rh pipe to the unistrut cross-piece.
