I have a dilemna in making sure I hang a porch swing securly. The porch is about 5 ft wide from the house to the beam and post support. The part that connects to the house is just toed in and notched to also sit on a facing board for more strength. I have 3 pictures. Is this secure enough?
The second question is in regard to having to install another board for spacing issues. The 2x6 rafters have 2x4s mounted flat against them and perpendicular. These are what the vinyl soffit panels are mounted to that create the porch roof. Therefore, I can't just mount the swing eye screws to the rafters because there is now a 1.5" space between the panels and the underside of the rafter. What is the proper procedure to mount some board under the rafter? I thought of taking a 2x10 and mounting it perpendicular to span 2 rafters and then changing the eye screws for eye bolts, but not sure it that would work. I can't mount to the middle of this piece, it would mount more toward the rafter. I guess that would defeat the purpose of trying to spread the load between two rafters.
I thought of just taking a 2x4 and bolting it with lag screws to the bottom of the joist, running along its length and then putting my eye screw through both the 2x4 and the joist. But I don't know how secure that is, now I am going through 1.5 inches of 2x4 and maybe 1 inch into the bottom of the joist. Any help from structural experts? I imagine I need to support 350 to 400lbs of load.
I guess one more option would be to get 2x8 and make my own beam running right next to another one and notch it in all the places I would need so it drops down that 1.5 inches and goes around the 2x4s and sits on the beam held up by the posts. But I'm not sure how to mount it and what my nail will toenail into on the house side. Thank you.
