Hey, I am making a simple 48×78 table out of 3/4 baltic birch ply, and simply screwing on metal legs from amazon.

What I am wondering is, do I need to make a sort of apron, or battens underneath to prevent warping is this not an issue with ply wood? I was also considering doing a sort of “X”

This is for indoor.

Let me know what you think

Definitely need some sort of bracing otherwise, that plywood will sag. Maybe wide edgebanding that provides strength—plus it will cover up the plywood edge.

Have your say...
