BIRD FEEDER: Supportless, all in one piece, screw in a plastic juice water bottle 48 mm thread (on big 5-6 l bottles)
Pierce the bottom of the bottle in two places and thread a rope, chain, or other means of hanging through. Fill the bottle with wild bird food.
Don't forget to seal the resulting holes so that water does not penetrate the bottle during rain or thaw.
Another option for attaching the feeder is to screw its bottom to a beam or railing.
Screw the bottle full of grains into the feeder, turn it upside down and hang on a tree or beam with some rope or some chain.
