Bowed platform top diy stand?

[NancyFish]

I’ve dragged out painting my 3/4” marine plywood platform top for a new stand (temps not optimal for paint). It’s laying flat inside but it definitely lifted maybe 1-2mm 3mm max on edges.

I’m trying to weigh it down, but if it doesn’t want to settle should I screw it on the frame anyways because the rimmed tank will even out — or scrap it for a new top?

This is the stand on its side, the frame to the left is the top, it has two rectangle gussets in the sides too.

You can get a level and shim the top flat. Unscrew a bit and add a filler like construction adhesive to level

I haven’t screwed it in yet, that’s just my top frame on the side left, I was going to screw and glue plywood to it. I’m hopeful screwing it down is plenty but didn’t want to if it wasn’t worth it safety wise

On this stand I used a scrap piece of granite to ensure it was level.

That looks sharp! I debated doing epoxy on our top trim to get a faux look like that, but it stinks the whole house up
