Step 2Prepare the Front Board
Try to avoid any knots or visible defects in the wood because they will make it infinitely harder to drill the LED holes.
Start by printing out the template attached to this step at a 1:1 scale.
Tape it to the back side of the front board, so the good side is facing down when the print-out is facing up.
Take the front board and place it template side up on top of the worst looking board. Then put that on the drill press.
Take a drill bit slightly larger than the flat-ended hobby bit and adjust the depth gauge so that the tip is just 0.8-1mm above the lower board, this is so it doesn't go all of the way through the front board. I strongly suggest using a test board first to see if it works. Drill at least 10 test holes (they will be used later!). A strong light should be able to shine through where the tip of the drill ended.
Drill one hole in each of the circles on the template as in the picture below.
