Before and after: my garage bench went from sagging plywood to dead flat in 2 weeks, was it the frame or the top? | Diy Builders - Freelance Forum - The Community for Independent Professionals
So you're telling me you spent two weeks fixing a bench and you're not even sure what fixed it? That's like me tightening every bolt on my bike and then being shocked it stopped squeaking. The frame and the top are a team, you can't just point at one and say "yep, that was it." My guess is the sag came from the whole thing being loose, and once you squared it up the top finally had something solid to sit on. But hey, if it's flat now, take the win and don't overthink it.
