IMHO...YOU DON'T NEED TO PUT 45 DEGREE PIPE ON THE BOTTOM. DEER WILL HAVE THE FOOD GONE IN THE PIPE IN 2 DAYS. IF YOU HAVE A VERY SMALL DEER HERD, YOU MIGHT WANT TO USE THE 45 DEGREE PIPE TO KEEP THE CORN OFF THE GROUND. I USE 6INCH PVC AT LOWES, DRILL TWO SETS OF HOLES TO RUN THE HANGERS THROUGH AND THEN HOOK IT TO A TREE ABOUT 1-2 INCHES HIGH, THE WEIGHT OF THE CORN WILL MAKE IT SELF FEED. IF YOU PUT IT TOO HIGH IN THE AIR, ALL THE CORN WILL RUN OUT.
