Step 32: Drill The Pen.
Next we need to drill screw holes in the pen. Place the alligator clip on the edge of the pen. Where you cut the bottom lip off of the alligator clip should line up with the edge of the pen, where the nose cone will butt up against it.
Once you have it lined up either drill through the holes of the clip or mark the holes with a ball point pen and then drill through.
