To build this pallet swing, I cut pallet lengthwise for the seating. The pallet was a heavy duty one ( 2x8 slats plus two 2x4's doubled to case 2x8's). Also, the pallet was extremely long. I framed this with 2x4's for a set portion of the swing. Next, I took a second pallet that was also long but lighter weight and cased in it with some of the other 2x4 were from the first pallet and framed it. I cut the remaining 2x8's for arms, drilled out holes in them for chain then added some bolts to the side for the chain. Sanded it and painted it. Mom lived it, said she could set and watch her birds.
