Tricky Tenons - Canadian Woodworking Magazine
The size of the tenons must match the size of the mortises in the stretchers and legs. This coffee table uses tenons that are ¼" thick, 1 ½" wide and about 4" long. I mill up three or four pieces of stock 1 ½" wide by 24" long and just over ¼" thick, then plane the pieces to exactly ¼" thick.
