A thick, flat hardwood top that turns a plain 2×4 frame into a real workbench. All five wide 8/4 boards edge-glue into a 44" × 27½" slab, 1¾" thick — heavy enough to plane, chop and hammer on without it skating around. Drop it on a base you already have, or build the simple 2×4 base in this plan. The short ends of the boards become shop blocks: a bench hook, bench cookies or a planing stop.
Quick Build — for experienced woodworkers
| Part | Qty | From | S2S size |
|---|---|---|---|
| Top pieces | 5 | Boards 1–5 | 44" × 5½" × 1¾" |
| Shop blocks (bench hook, cookies) | 5 | End of each board | 2⅞" × 5½" × 1¾" |
Top: five 5½" × 44" boards edge-glued (3 + 2, then the two panels) → 44" × 27½" × 1¾" (about 26¾" after jointing, about 1½" after flattening).
Optional 2×4 base: 40" × 24" footprint. Four legs at 34¼", four long rails at 40" and four end rails at 21", top rails flush with the leg tops and lower rails 6" off the floor. Glue and two 3" construction screws per joint. Five 8ft 2×4s.
Top to base: ⁵⁄₁₆" × 4½" lag screws with washers — round holes in the front rail, slotted holes in the end rails. No glue.
Finished size: 44" × 27½" (about 26¾" after jointing) × about 1½" after flattening. On the 2×4 base the work surface is about 36" high. The top alone weighs about 50 lb in maple.

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 Crosscut the boards. Square one end of each board and cut it at 44". Square up the 2⅞" pieces left on the ends and set them aside — they become shop blocks.
- 3 Arrange the top. Lay the five pieces side by side, best faces up. Alternate the growth rings on the end grain so any cupping evens out. Put the straightest, hardest board at the front edge — that's where you'll clamp and pound. Draw a chalk triangle across all five.
- 4 Joint the mating edges. Every edge that meets another must be dead straight. Dry-clamp the whole top: no light should show along any seam.
- 5 Glue up in stages. Glue three pieces into one panel and two into another. Next day, glue the two panels together. Every joint is long grain to long grain. Use cauls across the ends and clamp every 8", alternating over and under. The top comes out 44" × 27½" (about 26¾" once the edges are jointed).
- 6 Flatten. Scrape off the dried glue. The top is far too wide for a planer, so flatten it with a router sled or a jack plane, or pay a cabinet shop for a pass through a wide-belt sander. Check it with a straightedge in every direction — a flat top is the whole point of a bench.
- 7 Square the ends. Trim both ends square with a track saw, or a circular saw against a clamped straightedge. Cut from both faces if your saw won't reach through. Chamfer every edge about ⅛" so it won't splinter.
- 8 Finish. Sand to 150 and no finer. Wipe on Danish oil or boiled linseed oil, top, bottom and edges, and let it cure. Then rub in paste wax. No film finish — glue drips pop off wax, and a film finish chips and gets slippery.
- 9 Build or fit the base. Use any sturdy base about 34¼" tall, or build the 2×4 base below. Set the top on it upside down on a blanket, centred, with about 2" overhang at each end.
- 10 Fix the top. Drill two ⅜" round holes up through the front rail and two slotted holes (⅜" wide, 1" long front to back) up through each end rail. Pre-drill the top and drive ⁵⁄₁₆" × 4½" lag screws with washers. The round holes keep the front edge put. The slots let the back move — 27" of top grows and shrinks about ⅜" through the year.
Why glue up in stages? Five wide, heavy boards at once is a race against the glue. A three-piece and a two-piece panel are easy to keep flat, and joining them the next day is one seam to manage.
Why slotted holes? A 27½" top grows and shrinks about ⅜" across its width between summer and winter. Round holes at the front keep the front edge where your vise and clamps are. Slots in the end rails let the back of the top move, so it never cracks.
Why oil and wax, not varnish? Oil soaks in and hardens the surface, and wax makes glue and finish drips pop right off. It's easy to renew: sand out a stain and wipe on more oil. A film finish chips, and it lets work slide around.
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
- Dog holes: drill ¾" holes 4" in from the front edge on a 6" grid, square to the top, with a guide block. Round bench dogs and holdfasts drop right in.
- Front vise: bolt a 7" or 9" quick-release vise under the front left corner, with hardwood jaw pads cut from the shop blocks.
- Lower shelf: screw a ¾" plywood shelf onto the lower rails of the 2×4 base for tools and clamps.
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.
- The top weighs about 50 lb in maple. Get a helper to flip it and set it on the base.
- Use a router sled with the bit set to take light passes, and keep both hands on the sled.
- 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.
The five short ends make useful bench helpers. Two glued to a scrap base make a bench hook for sawing at the bench. Glue rubber shelf liner to both faces of the others for bench cookies that lift work off the top for routing and sanding. A block screwed at the end of the top is a planing stop.
About 36" suits most people for assembly and power tools. For lots of hand planing, go lower — about the height of your wrist with your arm hanging down. Change the 2×4 leg length to suit.
Yes, for a general shop bench. After flattening it's about 1½" of solid hardwood, heavier and stiffer than a doubled sheet of plywood. If you do a lot of heavy chopping, put a leg under the spot you work on most.
Planned offcuts: almost none. The 2⅞" piece left on the end of each board becomes a shop block — bench hook parts, bench cookies or a planing stop. All 5 boards go into the build.
No. A 2ft wide pack is too short for a workbench top. It makes a 22" × 27½" top for a small sharpening station or a benchtop stand — five 22" pieces edge-glued the same way.
