| Another feature worth noting are the small black tubes positioned in front of each stone. These are 6" sections of 1-1/2" ABS pipe that has a portion of 3/16" threaded rod (approximately 10" long) passing through perpendicularly to the inside of the tube. The rod is secured with a washer and nut on the outside of the tube. After assembling, I sharpen the end of the threaded rod which is simply pushed into the ground at a location that allows aiming of the flashlight beam. |
