I'm working on finishing a three season porch and have two "beams" that run across as part of the structure of the room. They are just 2 2x6 as one and just nailed in at the ends, as shown in the second photo. One even has a 1/4 space between the end of the "beam" and the framing, showing me they aren't really secure to the room. That being said, I want to hang a hammock or hanging chair of some sort when the room is finished. How can I secure it better to the wall? Can I use joist hangers and just notch out trim to cover them?
