My miter saw station warped after just 3 months in my garage shop

I built a big miter saw station back in September using standard 3/4 plywood and it started bowing near the sliding portion within 3 months... pretty sure the humidity swings in my garage did it. I see all these fancy builds online but nobody mentions how much the environment can mess with things. Anyone deal with that and find a fix that doesn't mean tearing the whole thing down?

Yeah, my garage tries to turn my tools into potato chips too.

...you know what always gets me is how the cold messes with the metal itself. Like my garage gets down to like 40 degrees in the winter and I swear the steel gets more brittle or something... I had a socket crack clean in half the other day just trying to loosen a bolt that wasn't even that stuck.

Miter saw stations are notorious for this because people use thin plywood and skip the cross bracing. You need to check if the warp is in the top itself or if the frame underneath shifted. If it's just the top, screw a sheet of 1/2 inch MDF on top as a sacrificial layer and brace the underside with some 2x4s running perpendicular to the saw. That MDF won't warp the same way and it's cheap to replace when the saw cuts get too deep. Also, get a dehumidifier for the garage during humid months or park a fan on it when you're not working. That alone saves most people from having to rebuild everything.
