Three solid hardwood open shelves for everyday plates, jars and mugs. Each 44" shelf sits on two curved wooden corbels and a hidden ledger strip that screws into the studs. Boards 1–3 are the shelves, board 4 makes six corbels, and board 5 rips into the three ledgers. No steel brackets and no glue-ups.
Quick Build — for experienced woodworkers
| Part | Qty | From | S2S size |
|---|---|---|---|
| Shelves | 3 | Boards 1–3 | 44" × 5½" × 1¾" |
| Corbel blanks | 6 | Board 4 | 7" × 5½" × 1¾" |
| Ledger strips | 3 | Board 5, ripped in thirds | 44" × 1¾" × 1¾" |
Shelves: one full board each, 44" × 5½" × 1¾" (wider boards give deeper shelves).
Ledgers: board 5 ripped in thirds → three 44" strips, screwed to the wall under each shelf's back edge with two #10 × 3½" structural screws per stud (3 studs).
Corbels: six 7" blanks from board 4, grain vertical, curved front, notched at the top back to sit over the ledger. Screwed to the ledger with 2 × #10 × 3" each, no glue.
Shelf: screwed up through the ledger every 10" and down into each corbel (counterbored and plugged).
Finished size: Each shelf 44" W × 5½" D (6–8" with wider boards) × 1¾" thick, standing 8¾" tall with its corbels. Rated about 25 lb per shelf, screwed into studs.

Why S2S only? The 6–8" wide 8/4 boards come S2S: both faces planed, edges rough. Plan on losing about ¼" per edge when you straighten them.
Our sizing assumptions: ⅛" per saw cut · 6–8" wide 8/4 S2S boards trimmed ½" each end and ¼" off each rough edge (5½" clean at the narrowest), planned at 1¾" thick · sizes drawn for the narrowest board in the pack. Wider boards give you a bigger offcut or a wider part — never a shortage.
Step-by-Step
S2S Lumber Pack (6–8" wide)
Surfaced 2 sides — straighten edges first
- 1 Prep the boards. Trim ½" off each end to remove any end checks. Joint one edge straight, then rip the other edge parallel (¼" off each rough edge is our planning allowance).
- 2 Cut the parts. Square one end of each board. Crosscut boards 1–3 at 44" for the shelves. Crosscut board 4 into six 7" corbel blanks with a stop block so they match.
- 3 Rip the ledgers. Rip board 5 into three strips, each about 1¾" wide, and crosscut them to 44". Use a push stick. Each shelf gets one ledger along its back edge.
- 4 Draw the corbel. Make a cardboard pattern 5½" wide × 7" tall, grain running up and down. At the top back corner, mark a notch 1¾" deep × 1¾" tall — the ledger sits in it. Mark 1¾" up the front edge from the top and 1¾" out along the bottom from the back. Join those two marks with a smooth curve that bulges out like a quarter circle (bend a thin strip of wood through them and trace it).
- 5 Cut the corbels. Trace the pattern on all six blanks. Cut the notch with a handsaw or bandsaw, then cut the curve with a bandsaw or jigsaw, staying just outside the line. Clamp the six together and sand the curves to the line so they match.
- 6 Sand the parts. Ease all the edges and round the front corners of the shelves slightly. Sand 120 → 180 → 220.
- 7 Mark the studs. At the wall, find the studs where each shelf goes and mark them on a ledger. A 44" shelf spans three studs at 16" centres. Plan the corbels 5" in from each end; if a corbel lands on a stud mark, slide both corbels an inch or two so every stud stays clear for a screw.
- 8 Join corbels to ledgers. On the bench, set the ledger into the notches of two corbels, back faces flush. Pre-drill and drive two #10 × 3" screws down through the ledger into each corbel. No glue — the grain crosses. Do the same for all three shelves.
- 9 Finish. Wipe-on oil or hardwax oil, 2–3 coats, on every face of the shelves, corbels and ledgers. Let it cure before loading the shelves.
- 10 Hang the ledgers. Draw a level line where the underside of each shelf goes (about 15" apart works for plates and jars). Hold a ledger-and-corbel unit with its top on the line. Pre-drill and drive two #10 × 3½" structural screws through the ledger into each of the three studs. Check that the corbels hang plumb.
- 11 Fit the shelves. Set each shelf on its ledger and corbels, back edge tight to the wall and ends even. Pre-drill and drive #10 × 3" screws up through the ledger into the shelf, about every 10". Then drive one counterbored #10 × 3" screw down through the shelf into each corbel and glue a wood plug over it. Each shelf holds about 25 lb.
Why a ledger and corbels? A loaded shelf tries to tip forward and pull its back edge off the wall. The ledger is screwed into every stud and holds the back edge. The corbels push against the wall below and carry the front. Together they make a stiff shelf with no steel showing.
Why notch the corbels? The notch lets each corbel hook over the ledger, so the ledger runs the full length of the shelf and the corbels sit right against the wall. Joined on the bench, each shelf goes up as one unit.
Does wood movement matter? Very little here. The shelves are single boards and every long part runs the same way. The corbels cross the grain, so they are screwed, never glued.
Make It Yours
- Straight brace look: cut the corbels on a 45° line instead of a curve for a clean, modern look.
- Rail for mugs: screw a row of cup hooks under the bottom shelf.
- Two-tone: walnut shelves on maple corbels.
Safety and Care
- Wear eye and hearing protection. Use a push stick for every rip under 4" wide.
- Pre-drill every screw — hardwoods split without a pilot hole.
- Mount into wall studs (or rated anchors sized for the load). Check for wires and pipes before drilling.
- Each shelf is rated about 25 lb spread along its length — plates, bowls and jars. Don't hang on it or use it as a step.
- Cut the 7" corbel blanks with a stop block and hold-down, never freehand small parts on a mitre saw.
Frequently Asked Questions
The 6–8" wide 8/4 pack comes S2S (faces planed, edges rough). Straighten the edges with a jointer, a table saw and a straight-line jig, a track saw, or a hand plane.
Yes, when the ledger is screwed into three studs. About 25 lb per shelf is a stack of dinner plates, a row of bowls and some jars. Keep the heaviest things near the corbels.
A 44" ledger still reaches two studs. Use three #10 × 3½" structural screws in each, and keep the load near 20 lb per shelf.
Yes. Drill through tile with a tile or glass bit first, then switch to a wood bit for the stud. Use a longer structural screw so at least 1¼" goes into the stud.
Planned offcuts only: about 3" off boards 1–3, about 4" off board 4 and 3" off the ledger strips. Cutting the corbel curves turns some of each blank into scraps; our yield counts the full blank. All 5 boards go into the shelves.
A 2ft wide pack is too short for six corbels on one board. It makes two 22" shelves: boards 1–2 are the shelves, boards 3 and 4 make the corbels (three each, one spare), and board 5 rips into the ledgers. A 22" shelf reaches two studs at 16" centres.
