James Merritt Dunlap, who lives in Alaska, made a knockdown trestle table that has self-tightening, shallow-tapered, loose-wedged tenons, good for enduring extreme humidity changes. Just slightly jarring the table brings the tenons further into the mortises and tightens the joints. Dunlap conditions the wood to predict movement, and glues up the tabletop. He explains how to make the apron assembly and join the trestle post and base. He uses a three-tenon slide-bolt connection and shows where it fits on the table, and then explains his self-tightening draw wedges. Exploded drawings clarify how this table fits together.
