Step 3 Getting Ready for LEDs

So now that you have the Sheet metal all measured and holes drilled in it, it is now to to get the backing ready and holes in that so we can start the LED process. The reason for adding this backing (Poster Board) on to the back of the Sheet metal is so that we can more easily work with the LEDs and the soldering process, since there is a lot of soldering involved. I will show you what I mean "more easily" in the next step.

So the easiest way to get the holes on the Poster board to line up with the sheet metal holes that you already cut is to just lay the sheet metal on top of the poster board. Line up a corner of the sheet metal to the corner of the poster board so two sides of the board line up with two sides of the metal. Then take a pencil and start tracing the outline of the sheet metal onto the poster board, along with all the holes in the sheet metal.

Now take the poster board and start cutting and drilling out the holes, but make sure to use a little smaller drill bit then what you used to drill the sheet metal, not only does this poster board make it easier to solder but it will hold all the LEDs in place.
