Drill Holes for LEDs

First off the hole positions need to marked. The clocks diameter was 9.25" so its circumference was about 29". Since I wanted 8 LEDs, I spaced the holes 3.65" apart. I cut a bendable piece of plastic to use as a ruler.

The Images below cover the following steps.

- Cover the area where the holes will be with some painters or masking tape.

- After testing for how far away from the wall I needed the LEDs, I found a notepad and pen that were the right height for the LEDs.

- Mark a line all the way around.

- Use a ruler to mark the spacing of the holes to be drilled on the line that was already drawn.

- Drill the holes, be careful and precise. I used a hand drill and it worked fine.
