These squirrel-proof bird feeders are my design, the wooden-shingled feeder made completely of cedar wood. The roof has approximately 750 shingles wood I made. The copper-root feeder is cedar wood with a copper roof. I made all the parts on both feeders.
The feeders are approximately 24" tall and 28" wide. The feeders are electrified with the same type the farmers use to keep the animals in the field. The copper tubing that runs on the outrigger is the hot part! the ground wire runs along the top of the hand rail. It works - no squirrels!
