Advice on gate design
I am building a double 4' cedar gate (8' total) similar to the picture below. It is T&G and i would like it clean both sides (no diagonals). I have considered sandwiching a steel gate frame between two T&G layers, but would prefer not to add the weight, thickness or cost. Of course, I don't want to see any sag over time. I am trying to figure out the joinery/construction of the pictured gate, and what i can do to ensure it does not move over time. Glue all joints and T&G?
Advice appreciated! :)
