A thick hardwood bar top that sits right on your deck railing — a place to set drinks and plates while you stand and look out over the yard. Two wide 8/4 boards edge-glue into a 44" × 11" ledge. A full-length cleat screws down to the 2×6 rail cap, and six sloped wooden brackets carry the 5½" overhang on the deck side. No legs, no posts to set.

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": boards 1–2 are the ledge, board 3 the rail cleat. Clamp a stop block at 9" and cut boards 4–5 into three bracket blanks each.
- 3 Glue up the ledge. Joint the mating edges of boards 1–2 until no light shows. Edge-glue them into a 44" × 11" ledge with waterproof glue (Titebond III), long grain to long grain. Clamp every 8", alternating over and under, and leave overnight.
- 4 Shape the brackets. Stand each blank with its grain up and down. Mark 1½" in from the back along the bottom and 5" in from the back along the top, then join the bottom mark to a point 5½" down the front edge — a 45° slope. Saw just outside the line and sand all six to match. Trim the tops to 5" deep if your boards are wider.
- 5 Drill the brackets. Drill two ¼" clearance holes through each bracket from the slope to the back, about 2" and 5" up from the bottom. Counterbore them ⅜" from the slope side so about 1¼" of wood is left behind the screw head.
- 6 Flatten, round and sand. Flatten the ledge seam, round every edge and corner of the ledge with a ¼" roundover, and ease the bracket edges. Cut two 3½" cup holes with a hole saw now if you want them (see Make It Yours). Sand 120 → 180 → 220.
- 7 Oil every face. Flood on exterior oil (penetrating deck or teak oil), let it soak 20 minutes and wipe off. Two coats on every face, end and hole — the underside and ends matter as much as the top outdoors. Re-oil every spring, or when water stops beading.
- 8 Fix the cleat to the rail. Set the cleat flat on the rail cap, flush with the cap's yard-side edge and centred where you want the bar. Pre-drill and drive #10 × 3" exterior screws (stainless or coated) down through the cleat into the cap every 8", in a line down the middle.
- 9 Fix the ledge. Set the ledge on the cleat, back edge flush with the cleat's back edge, so about 5½" hangs over the deck side. Drill ⅜" counterbores ½" deep along the middle of the cleat every 10", pilot through, and drive #10 × 3" exterior screws into the cleat. One centre row lets the ledge move both ways with the weather.
- 10 Hang the brackets. Space the six brackets about 8" apart under the overhang, tops tight to the ledge. Screw each one through its counterbores into the rail, a post or a baluster with #10 × 3" exterior screws. If the rail sits back from the cap edge, pack it out with an offcut spacer so the bracket stands plumb. Then drive one #10 × 3" exterior screw down through a counterbore in the ledge into each bracket.
Why a cleat? The rail cap is often cupped, worn or out of level. The cleat gives the ledge a flat, solid base, lifts it off standing water on the cap, and puts plenty of screws into the cap along its full length.
Why one row of screws? Outdoors, an 11" ledge can grow and shrink ¼" across its width. A single row of screws down the middle of the cleat lets it move both ways without splitting. The bracket screws near the front are only snug.
Which species last outdoors? White oak is the best choice — it resists rot. Walnut and cherry also do well with yearly oil. Maple, ash and red oak weather and grey faster; they work, but oil them twice a year and expect them to darken.
Why pre-drill? Maple, oak and hickory split if you drive a screw without a pilot hole. Pre-drill every screw and countersink so the heads sit flush.
Make It Yours
- Cup holes: bore two or three 3½" holes through the overhang between brackets so drinks can't tip off.
- Bottle opener: screw a cast-iron opener to an offcut block and mount it on a post below the ledge.
- Coasters: resaw the bracket-board leftovers into ½" slices for matching coasters.
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.
- Rated for about 40 lb of drinks and plates. It is not a seat — never sit, stand or lean your full weight on it, and keep kids from climbing on it.
- Check that your deck rail is solid before you start: shake the posts. A loose rail must be fixed first.
- Never remove balusters or rail parts to fit the ledge — the railing is a safety guard first.
- Wear a dust mask when cutting and sanding, especially exotics (padauk, purpleheart, sapele).
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.
It is made for a 2×6 rail cap (5½" wide). For a 2×4 cap, rip the cleat to 3½" and the ledge overhangs the deck side by about 7"; use the same brackets. Composite and metal railings need different fixings — check with the maker.
Yes. The ledge is oiled on every face and sheds water, so it can stay put. Brush snow off, and re-oil in spring. Expect the colour to soften to a silver-brown over a few years unless you oil it often.
About 40 lb spread along its length — drinks, plates and elbows. The six brackets carry the overhang. Don't sit on it.
Planned offcuts only: about 3" off boards 1–3 and about 19½" off boards 4–5, plus the wedge cut from each bracket slope. Use the leftovers for spacers, coasters or an opener block. All 5 boards go into the ledge.
A 2ft wide pack makes a 22" ledge for a small balcony: two boards for the ledge, one for the cleat, and three brackets from boards 4–5 with plenty left for coasters.
