T10.1 · Rebate markFor a corner rebate joint in 16 mm plywood with hand and portable power tools, mark the rebate width (the thickness of the mating board) and depth (about half to two-thirds of the board's thickness) with a marking gauge.T10.2 · Rebate cutClamp the board securely and cut the rebate with a hand-held router fitted with a rebating bit, or a straight bit guided by the fence, taking several shallow passes to reduce tear-out.T10.3 · Rebate fitCheck the fit by dry assembly, then glue and nail or screw through the side into the rebate. Cramp, check for square by measuring the diagonals, and clean off excess glue.T10.4 · Tenon sizeFor a mortise and tenon, make the tenon about one-third of the rail's thickness; this leaves enough timber either side of the mortise for maximum strength and stability.T10.5 · MortiseMark out with a mortise gauge set to the chisel width. Cut the mortise with a mortise chisel and mallet, a drill press with a mortising attachment, or a hollow chisel mortiser, to slightly deeper than the tenon length.T10.6 · Tenon cutCut the tenon cheeks with a tenon saw and the shoulders square, or use a tenoning jig on the table saw. Pare to a firm push fit, dry assemble, then glue and cramp.
