Vos, go to http:// buildgear.cjb.net/ and scroll all the way down to Bushy-tail Cafe. It's has some pretty cool setups that are cheap to build. I did the one with the 5 gal bucket and used a 24" piece of 3" pvc with a toliet flange glued to the top so that I could bolt it to the bucket, cut a 1/2" x 2" divot off the bottom of the pvc( for the corn to slide out), and then put a board on the bottom of the pvc to hold the corn in and so that the squirrels had a place to jump onto.
