Question: Looking over the current and past issues of Woodworking Magazine, I see how drawboring or wedging a mortise and tenon joint will improve the strength and fit of the joint. But is there a reason to pick either drawboring or wedging over the other technique in terms of the strength or durability of the joint?
The only advantage I can think of so far is that it might be easier to disassemble a drawbored joint.

Answer: I’m not aware of any studies that compare the relative strengths of these two joints. For me, they both fit into the category of “stronger than typically required.”
And that is probably why both joints show up frequently in chairs, which are the most-abused category of furniture.
