LED Replacement Fluorescent Tube

Step 3 Drill

This process is best done with a drill press. If you are creating an 87 LED bulb like the one designed, it will take approximately 20 minutes to drill all of the holes. Grab a piece of scrap lumber and clamp it to your drill press's stage. Align it to be square to the drill press stage, and the correct distance to ensure that all of the holes drilled fall in the same plane and on the score marks. The ideal drill bit size to use is 3/16 inches. This size is slightly smaller than required but allows the LEDs to be mounted without glue. This is where you can omit the lengthwise score marks by ensuring the jig is clamped in the correct location.
