I built the PVC feeder seen here and all over the Internet. A few problems arose; - when it rained the pellets got soaked - way. To much feed ended up on the ground To solve the rain problem I purchased a small eave flashing, $ .52 at Lowes. I bent it around the PVC and attached with three small machine bolts and nuts. To stop feed from getting flung on the ground I purchased a 3" test cap, cut it in half and glued it with PVC cement on the bottom half of the opening. Three weeks in and it appears this solved my problems.
