I made a drop feeder today. I took a 5 gallon bucket, drilled a hole in the center of the bottom, took a 3 ft long 1" PVC with a T on one end, slid it through the hole, hung it from a tree. Now when the pipe moves corn falls through the pipe. Works well. Im also going to make one like Bandhunter mentioned. I have a coon problem so hopefully the drop feeder will work.
