Cut legs A & rails B, C to size. Cut hand hole & mortises for hinges in back rail. Cut half lap joints in legs & rails. Lay assembly on bench & clamp swing-leg assemblies on top in open position. Make sure top edges & outside faces of swing-leg rails
Note the legs are plenty strong to support this table without the typical bracing on the lower legs. The braces have two inch structural screws. I like this idea rather than a streatcher along the bottom. I need room to tuck the chairs on the ends.
