Step 8Holing the donut
Then use a drill (a drill press is great here) to make 2 holes per LED. Make the holes where each small circle crosses the large circle lines so the LED can be tuned in or out to direct the light to the focal point near the lens.
Now use the large drill bit to make a hole somewhere within the inner circle. Cut out the inner circle to finish "the donut" with a scroll saw. If you are following closely you will notice I cheated the order a bit for the pix.
At this point remove the masking tape, take a moment to admire your handiwork.
