I used 3/4 inch thick by 3-1/2 inch wide treated wood to make this feeder. You can use other woods that will stand up to the weather. You could also paint it to protect it.
I used three 6 foot long 3/4" x 3-1/2" weather treated boards.
Zinc treated screws
2 Plumbing Pipe Floor Flanges
Short section of pipe threaded on both ends.
Pipe size determined by how tall you want it to stand. I would use 1-1/4" if I had an
8 foot free standing bird feeder.
