I built this bird feeder using normal plumbing supplies. I did not take photos when I built it sop these are all the finished product. If not sure how to do plumbing soldering there are plenty instructions on youtube.
Step 1: Create the Base - All Parts Except the Baffle Are Normal Plumbing Supplies
Be sure to use deck screws so they don't rust. The joint piece in the middle was because I had to add on. The squirrels were able to jump up and eat the bird feed, so I made it taller.
Build the structure. The baffle is available from gardening stores. Again, make it high enough so squirrels cannot jump up to the feeder. They are relentless in trying to get as high as they can for the goods!
Hang the feeders using eye bolts (exterior grade so they don't rust)
