A hardwood coat hook rail is a useful first project for learning to cut mortises by hand. The joints hold each hook upright and resist the twisting force of coats and bags, while the rail itself is small enough to work on a bench. This design uses three hardwood pegs fitted into a 24-inch-long backboard. Allow a weekend, including glue-up and finishing.

Materials and sizing
Use a straight-grained board of cherry, maple, oak, or another stable hardwood. The backboard should be about 24 inches long, 5½ inches tall, and ¾ inch thick. Make three hooks from stock about 1¼ inches wide, ¾ inch thick, and 5 inches long. These dimensions give a practical 3½-inch projection after the pegs are fitted, but you can shorten them for a narrow hallway.
Choose a board without knots or checks where the mortises will go. A knot near a joint can split when you pare the opening. If you need to buy stock, a hardwood board is convenient, but a local lumberyard often lets you inspect grain and color before buying. Match the hook grain direction to the length of each hook; short grain at the shoulder is more likely to break under a heavy load.
Tools and joint choice
Each hook has a ¾-inch-wide tenon at its base, cut to fit a ¾-inch-thick backboard. A ¾-inch-square mortise gives a simple, strong joint and leaves enough material around the opening. The pegs can be shaped with a small curve or left square-edged with a chamfer.
You’ll need a marking gauge, square, sharp chisel, backsaw, mallet, and clamps. A sharp bench chisel is more important than an expensive set: one ¾-inch chisel can cut these mortises, though a narrower chisel helps clean corners. A drill is optional for removing waste, but the walls and ends still need to be pared accurately by hand.
| Method | Best for | Trade-off |
|---|---|---|
| Chisel-only mortise | One rail or occasional joinery | Quiet and controlled, but slower |
| Drill out waste, pare to line | Faster rough removal | Easy to overrun the layout if the bit wanders |
| Router or mortising machine | Repeated, identical joints | Quick in batches, but setup may not pay off for three joints |
Prepare and mark the parts
Flatten and square the backboard before laying out the joints. Mark a centerline along its length, then locate mortise centers 4, 12, and 20 inches from one end. These positions leave 4 inches at each end and 8 inches between hooks. If the rail will carry bulky coats, widen the spacing to 9 or 10 inches and use a longer backboard.
Set the marking gauge to ⅜ inch and score both sides of each mortise from the backboard’s front face. Use a square to draw the ends, making each opening ¾ inch long. Keep all three mortises centered on the board’s height. Knife lines are useful: they give the chisel a crisp edge and reduce splintering. Mark the front face clearly so you don’t accidentally cut from the wrong side.
On each hook blank, mark a ¾-inch-wide tenon centered on the thickness. Leave a shoulder all around the tenon so it meets the backboard cleanly. A ¾-inch tenon length is enough for this rail; making it longer does not compensate for a loose fit and can make assembly awkward.
Cut the mortises and tenons
Clamp the backboard flat and secure it against movement. Start each mortise by chopping a short distance inside the layout, with the bevel facing the waste. Work from both ends toward the middle, removing chips every few blows. Keep the chisel vertical and stop just short of the final depth, about ⅝ inch. Pare the walls to the knife lines, then deepen the opening to ¾ inch. A mortise that flares at the face may look acceptable dry but leave a visible gap around the hook.
If you use a drill to speed waste removal, fit a depth stop and bore a row of small overlapping holes within the layout. Stay at least 1⁄16 inch from the marked edges; drill-bit wander can nick a finished wall. Then pare the remaining material square. A drill bit matching the mortise width is not a substitute for a clean, square opening.
Saw the hook tenons just outside their lines, then pare to the marks. Test each one in its own mortise. It should slide in with firm hand pressure and seat against the shoulder without a mallet. If it needs hammering, shave the tenon in small increments. A too-tight fit can split the backboard during glue-up; a loose fit can rack under a bag’s sideways pull.
Shape and assemble the rail
Round the exposed hook ends and soften their edges with a rasp or block plane. Leave the shoulders square so they bear evenly against the backboard. Sand the parts through 120 and 180 grit before assembly; sanding inside a narrow joint later is difficult.
Dry-fit all three hooks and check that they sit at the same angle. If one tilts, check the mortise walls and tenon cheeks rather than forcing it straight during clamping. Apply a thin coat of wood glue to the tenon faces and inside each mortise, then seat the hooks. Use a straightedge to align their ends. Wipe away squeeze-out with a barely damp cloth, and let the glue cure according to its label—typically overnight before sanding or loading the rail.
Mounting and finish
Sand the assembled rail to 180 or 220 grit and apply a finish suitable for indoor furniture, such as hardwax oil or wiping varnish. Follow the product’s drying instructions and keep the hooks unloaded until the finish has cured. A hardwax oil finish is easy to refresh, while varnish generally offers a more protective film but needs careful repair if scratched.
Mount the rail into wall studs whenever possible. Predrill through the backboard and use two or three screws long enough to penetrate the stud by at least 1½ inches, accounting for the board and drywall thickness. If the stud spacing does not match the rail, add a separate mounting cleat or use rated wall anchors; don’t rely on small nails or screws driven only into drywall. Test the installed rail with a gradual load before hanging a heavy winter coat or loaded bag.
