So, here is your cut list:
6 - rectangles 8.75 inch x 1 inch (these will be what holds the hood in place by being positioned on the outside of the tank)
2 - isosceles trapezoids with a 15.25 inch long base, a 8.75 inch short base, and 8.75 inch sides (the "base" are the parallel sides of the trapezoid)
2 - rectangles 1 inch x 10 inches
You will also need wood glue and silicon. You can use silicon instead of wood glue but make sure you apply it generously if you do.
Steps:
1. Place your trapezoids on the ground and wood glue the 8.75 inch long rectangles to the 8.75 inch sides and bases of the trapezoids. Let that cure (12-24 hours).
2. Once done, silicon the gaps on the edges. Smooth with finger and let that cure (2-4 hours)
3. Scrape off excess silicon.
4. Position the trapezoids with the 15.25 inch bases, 8.75 inches away from each other.
5. Glue the 10 inch rectangles to the trapezoids to form a bridge. Do so as close as possible to the side for optimal space for lighting.
Good luck with the DIY hood!
