The gap behind the wedge is for expansion and contraction of the stretcher without having the wedge come loose. You are actually cutting the wedge mortise bigger to have this gap.

That gap is where you stash your retirement cash. Safe and secure, who would even think of looking there! But for real all this wood expansion stuff is something we all need to learn and keep in mind when building solid wood projects.

Great idea $tudie. Bet it gets a better return than trusting the lying ba$7@%ds at Merril Lynch! ;-)

Pretty much like John describes, if the gap wasn’t there, the wedge would bottom out in the mortise and there would be no way it could tighten the joint over time as the wood in the post shrinks or the length of the tenon increases.
