Tweeters,
Tor Ivar's web site was a gem for me. I had been seeking a sophisticated feeder design that could be made with inexpensive materials. My fourth, fifth, and sixth grade Naturalists had expressed interest in building feeders.
Tor Ivar's "Silo Box" is very ingenious.

His graphics are well done in my estimation. He has responded quickly to my requests for further information. Have a look!
