This is a perfect project for spring. I think picnic tables are a pretty good seller no matter where you are. My biggest pet peeve regarding picnic tables is sitting down on a wobbly one. If I’m enjoying that fresh off the grill juicy hamburger I don’t want to be jarred around when someone sits down opposite of me. So to stop that I designed a slightly stronger table with more emphasis on lateral movement. There is a 4” support beam that runs the length of the seat that really strengthens the entire build. Both bench seats and the table top are secured from below with pocket hole screws. No screw heads visible from the top. Glued, screwed, and bolted. So long as you properly account for mother nature, these should last a long, long time.
