Hmm. My 2 cents. What is directly above the attach point? There could be a noise translation issue. If you wife is watching boxing while you’re down there injuring the bag, it’s probably a moot point. Baby’s crib, or the dog’s bed? Prolly not a good idea. Personally, I’d laminate some plywood to both sides of the OSB portion for anything like this. OSB in it’s state as you see it possesses great aggregate strength, but with all that pounding, I’d want local reinforcement to minimize the pounding from point loading, potentially tearing it locally. Also, I’d drill the holes mid beam, not near the top or bottom. A bag that big may do a good job of attenuating your wife-beatin’ urges, :) but I’m a conservative kind of guy when it comes to designing a structure.
