I once I had the beams glued together (each is 2 2”x8:x16’ ACQ boards glued together) I brought them out to the back yard and marked where the trees and mounting brackets went. Then I installed ⅜” carriage bolts through both boards to reinforce the glue joints. Finally I installed the spacer blocks and clips to attach the boards to the trees. The video is a little wavy. That’s YouTube, trying to stabilize my very wobbly video.
