Recently purchased home and saw existing eye lag screw or bolt coming from front porch ceiling. Rolled the dice (hoping for bolt + reinforcement), did not remove vinyl ceiling to inspect carpentry. Installed swing and it failed with 2 people. Eye lag screw was inserted directly into joist.
Would like reinforce joists to ensure 700lbs load from swing. My idea is to install 4x4s across the joists using hangers/braces, but the rafter is in the way such that the hanger will not be flush against the joist. Question 1) Is there a hanger/bracket for this situation? Question 2) Is my idea a good one?
Also the joists are 2 feet apart - Question 3) is that too much space? Maybe I need to install another joist in between so the distance is only 1 foot.
I appreciate any help with this project.
