i made a feeder out of pvc and it works really good. have no picture but can tell you how to make it.

all you need is 4 inch pcv pipe.
pvc glue
and a hack saw.

take and cut your pipe 3 ft long and glue a forty five degree elbow on it. then cut you another pie about 1.5 feet and glue that to the elbow. drill some holes in the bottom of it sorain water can drain. Lastly paint it you favorite hunting color , not hunter orange.
