Materials

Build steps

1. 1

   Final confirmation of parts and tools

   ≈ 15 min

   Prepare two pieces of 2x6 lumber (38×140×900mm), four pieces of 2x4 lumber (38×89×392mm), two pieces of 2x4 lumber (38×89×900mm), and forty 65mm coarse-thread screws. Tools include an electric driver, handsaw, measuring tape, carpenter's square, #120/#240 sandpaper, level, two F-clamps, brush, and paint tray.

   Measure

   W 900 mm

   MeasureSTEP 1 / 20

   Tip

   • Though 40 screws are specified, prepare over 50 for replacements in case of mistakes.
   • Cutting at the home center costs 30-50 yen per cut. It's more precise and cheaper than cutting by yourself.

   Watch out

   • Though 2x4 and 2x6 lumber have the same thickness (38mm), their widths differ (89mm/140mm). Pay attention not to mix them up.
   • Skipping the finishing step leads to stains from hand sweat or spills. Always apply oil finish to protect the wood surface.
2. 2

   Securing the workspace

   ≈ 10 min

   Secure a flat workspace about 1500mm×1500mm, and cover with a blue sheet to manage wood debris. Place a workbench or two sawhorses closely to support the long 900mm material horizontally. Confirm the availability of power outlets, lighting, and ventilation.

   Inspect

   No wobble ✓

   InspectSTEP 2 / 20

   Tip

   • An unstable workbench can distort right angles. Check for any wobbling before starting.
   • The height of the workbench should be at your waist to navel level. Too low can strain your back.

   Watch out

   • Cutting and sanding generate a lot of wood dust. Perform in a ventilated balcony or garage and immediately vacuum after finishing.
   • Using extension cords with multiple taps reduces voltage, lowering the torque of the driver. Use a single line extension.
3. 3

   Marking cut lines on lumber

   ≈ 15 min

   Use the carpenter's square and 2B pencil to draw cut lines on all lumber: two top boards at 900mm, four legs at 392mm, and two apron boards at 900mm. Mark the pilot hole positions on the back surface too. Label parts such as 'Top board A', 'Top board B', 'Leg LF/LB/RF/RB', and 'Apron front/back' to avoid confusion during assembly.

   Mark a line

   Use a try square

   MarkSTEP 3 / 20

   Tip

   • Draw lines lightly with pencil at first, then retrace once firmly to make visible markings.
   • Clamp four leg pieces together and cut them simultaneously rather than cutting one at a time to ensure uniform length.

   Watch out

   • There is a 3mm difference between the inner and outer measurement edges of the carpenter's square. Always use the outer edge (measurement side).
   • If parts are not identified, you may forget which is which later. Write labels on the back with pencil.
4. 4

   Cutting the top board (2x6 lumber)

   ≈ 20 min

   Cut two pieces of 2x6 lumber to 1200mm each. Skip this step if using home center cutting service. When cutting by handsaw, cut just 0.5mm outside the pencil line on the waste side. Having a helper support the board at the end prevents chipping. For solo work, use two sawhorses and let the cut-off piece drop naturally.

   Cut

   Use the in-store cut service

   CutSTEP 4 / 20

   Tip

   • Saw by pulling (draw stroke), not pushing (push stroke). Focus on the draw cut.
   • If the cut edge splinters, lightly sand immediately with #120 grit to reduce workload in later sanding.

   Watch out

   • If the length shortens by 2-3mm, no need to match exactly 1200mm apron length. A slightly shorter top board looks fine if edges are aligned.
   • Burn marks or smoke during sawing indicate dull blades. Replace blade or switch to circular saw.
5. 5

   Cutting leg and apron boards (2x4 lumber)

   ≈ 15 min

   Cut four leg pieces to 392mm and two apron pieces to 1200mm from 2x4 lumber. For precise leg length, clamp all four legs together and cut at once. Check squareness with carpenter's square during cutting to avoid angled ends causing instability.

   Cut

   Use the in-store cut service

   CutSTEP 5 / 20

   Tip

   • Clamp the four leg pieces together and cut simultaneously to minimize length differences.
   • Cut apron boards the same length as top boards, using the same guide for consistent sizes.

   Watch out

   • If one leg is shorter, cut all four to the shortest length. Uneven leg lengths cause permanent wobbling.
   • If the saw blade enters at an angle, the cut end will not be square. Use draw-cut method to maintain angle.
6. 6

   Sanding all parts (#120 grit)

   ≈ 25 min

   Sand all parts with #120 sandpaper. Sand both sides and four edges in the direction of the wood grain. Be careful not to round corners by sanding too aggressively; a light pass is sufficient. Pay extra attention to cut surfaces for any fuzz. Top boards used for seating should have a smooth finish prioritizing tactile feel.

   Sand

   #120

   SandSTEP 6 / 20

   Tip

   • Wrap sandpaper around a wood block for even pressure rather than hand sanding.
   • Wear a dust mask and goggles as sanding produces much dust. Gloves protect fingertips better than bare hands.

   Watch out

   • Sanding too much in one spot causes depressions. Maintain consistent strokes over the entire surface.
   • Sanding against the grain raises fibers and leaves roughness. Always sand along the grain direction.
7. 7

   Final sanding (#240 grit)

   ≈ 15 min

   Use #240 sandpaper for finishing sanding on all surfaces. Focus on the seating surface of top boards and frequently touched areas such as apron upper edges and leg corners. Remove sanding dust completely with brush or vacuum. Check with bare hands for any roughness or snagging.

   Sand

   #240

   SandSTEP 7 / 20

   Tip

   • Wiping with a dry cloth after #240 sanding also degreases the surface before finishing.
   • Avoid exposing the bare wood to sunlight after sanding; proceed quickly to finishing to prevent uneven coloring due to UV.

   Watch out

   • Remaining sanding dust causes blemishes in finish. Vacuum thoroughly before finishing.
   • Any single snag on the seating surface will catch clothing. Carefully check by hand.
8. 8

   How to drill pilot holes

   ≈ 10 min

   Drill φ3mm pilot holes at screw locations. Attach two holes each at leg-apron joints, and four holes total at top board to apron joints. Pre-drilling prevents wood splitting and guides screw straight. Use masking tape on drill bit to mark depth and avoid through-holes.

   Drill a hole

   φ3mm

   DrillSTEP 8 / 20

   Tip

   • Pilot hole diameter should be 70-80% of screw shaft diameter (65mm coarse-thread screw shaft is 4.2mm), so φ3mm is ideal to prevent splitting.
   • Masking tape as depth marker prevents drilling through the wood. Tape leaves no residue when removed.

   Watch out

   • Driving screws without pilot holes in cedar or SPF lumber causes splitting 100% of the time, especially near end grain.
   • Drilling at an angle results in angled holes and misaligned screws. Keep drill perpendicular to surface.
9. 9

   Temporary assembly of one side leg frame

   ≈ 15 min

   Using two leg pieces (392mm) and one apron board (900mm), loosely assemble one U-shaped leg frame. Align apron bottom 20mm above leg bottom (seat height 430mm minus top board thickness 38mm and apron top position). Clamp with F-clamps and check right angle with carpenter's square.

   Build the frame

   Check for square

   AssembleSTEP 9 / 20

   Tip

   • Mark screw hole positions with pencil during temporary assembly to save locating time during final fastening.
   • After clamping, lift slightly to confirm no wobble; movement indicates improper squaring.

   Watch out

   • Incorrect apron height will cause mismatch with opposite frame. Mark with pencil before assembly.
   • Wood debris under the carpenter's square alters right angle measurement. Clean the surface before checking.
10. 10

    Screwing the leg frame on one side

    ≈ 10 min

    Fasten apron and leg pieces with 65mm coarse-thread screws. Use two screws per joint, staggered vertically. Keep clamps on while driving screws; remove only afterward. Sink screw heads about 0.5mm below the wood surface to improve finish adherence.

    Drive screws

    コーススレッド 51mm

    ScrewSTEP 10 / 20

    Tip

    • Drive two screws slightly angled outward (opposite 'V' shape) instead of parallel to improve withdrawal strength.
    • Set impact driver torque to medium; finish tightening by hand by rotating 1/4 turn.

    Watch out

    • Driving screws too deep can split wood grain and reduce strength; keep flush or just below surface.
    • If screws emerge at an angle askew from pilot hole, remove screw, fill with wood filler, let dry, then reposition screw correctly.
11. 11

    Assembling the opposite leg frame

    ≈ 20 min

    Use the first leg frame as a template to build the second leg frame with identical dimensions. Lay two frames side by side and confirm apron board height and leg lengths match. Ensure leg orientation and grain direction are consistently aligned for symmetry.

    Build the frame

    Check for square

    AssembleSTEP 11 / 20

    Tip

    • Overlay first assembled frame onto the second to align precisely.
    • Orient the leg side with more attractive grain outward for better appearance.

    Watch out

    • Unequal apron heights cause the top boards to tilt. Compare both frames side by side before assembly.
    • Forgetting to mirror screw positions from the first frame results in poor appearance.
12. 12

    Preparing to connect left and right frames

    ≈ 10 min

    Place the two leg frames 350mm apart (bench depth). Position the second apron (900mm) between the oppositional legs and clamp temporarily. Measure the two diagonals with a tape measure; lengths within 5mm difference are acceptable. Greater difference indicates frame distortion.

    Measure

    W 900 mm

    MeasureSTEP 12 / 20

    Tip

    • Measuring diagonals to confirm squareness is fundamental in cabinetry and furniture assembly.
    • The 350mm frame spacing corresponds to the top boards' depth; verify by measuring all four corners.

    Watch out

    • Diagonal difference over 5mm causes parallelogram distortion. Loosen clamps and adjust.
    • Uneven floor causes frame misalignment even during temporary assembly. Use a level workspace.
13. 13

    Driving screws for the second apron board

    ≈ 10 min

    After confirming diagonal measurements, fix the second apron board to legs using 65mm coarse-thread screws. Use two screws per joint. Fasten all screws on one side first (four screws), then the other side to avoid frame distortion. Re-check diagonal measurements after fastening.

    Drive screws

    コーススレッド 51mm

    ScrewSTEP 13 / 20

    Tip

    • Fix one side completely before the other to minimize distortion.
    • Use #2 Phillips driver bit. #1 bit causes cam-out and strips screw heads easily.

    Watch out

    • Fastening both sides simultaneously distorts diagonals. Always alternate sides.
    • If distortion is found after fastening, loosen screws, reposition, and retighten.
14. 14

    Checking leg frame level

    ≈ 10 min

    Place the assembled leg frame on the floor and check the top surface level with a level tool. Confirm levelness in front-back, left-right, and both diagonal directions. If wobbling occurs, insert thin shims under the short leg(s) or sand longer legs by 2-3mm to match.

    Check level

    Level ✓

    LevelSTEP 14 / 20

    Tip

    • Check level on all four edges of the top surface, as one side levelness does not guarantee overall flatness.
    • Smartphone level apps are acceptable but a 300mm builder's level is faster and more accurate.

    Watch out

    • Uneven floors do not guarantee wobble; check legs first before suspecting floor.
    • When sanding legs, do so gradually by 1mm increments and check frequently to avoid over-sanding.
15. 15

    Placing and temporarily fixing the top boards

    ≈ 10 min

    Place two top boards (900mm) on the leg frame. Leave a 5mm gap between boards for rainwater drainage and expansion. Overhang both front and rear edges evenly relative to the frame. Use 5mm spacers (coins or small wood pieces) and clamp for temporary hold.

    Lay the top board

    5mm 間隔

    Top boardSTEP 15 / 20

    Tip

    • Coins can act as 5mm spacers (100-yen coin ~1.85mm, 500-yen ~2mm; stack coins to reach desired thickness).
    • After determining top board front side, label with masking tape 'front' for orientation during assembly.

    Watch out

    • Boards placed tightly together allow water accumulation causing damage; maintain at least 5mm gap.
    • Opposite grain directions on boards cause differing warping direction and distortion; orient grain consistently.
16. 16

    Pilot holes and fastening top boards

    ≈ 15 min

    Drill φ3mm pilot holes and fasten top boards to apron boards with 65mm coarse-thread screws. Apply four screws per top board: two on front and two on rear apron boards, totaling eight screws. Align screws at the apron center and position them at least 20mm from top board edges. Screw heads must be flush or 0.5mm recessed.

    Drive screws

    コーススレッド 51mm

    ScrewSTEP 16 / 20

    Tip

    • Determine screw positions on visible top board surfaces before screwing for neatness.
    • Avoid screwing in top board centers to prevent clothing snags; limit screws directly above aprons.

    Watch out

    • Screw heads protruding from top boards can damage clothing or skin. If overdriven, remove and reposition screws.
    • Placing screws closer than 20mm from edges causes splitting.
17. 17

    Final check of overall level and distortion

    ≈ 10 min

    With top boards fastened, check levelness again using a level tool. Test stability by sitting on the bench and verify no creaking or wobbling. Address wobble by sanding leg bottoms or adding adjustable pads.

    Check level

    Level ✓

    LevelSTEP 17 / 20

    Tip

    • Body weight test reveals distortions unnoticed by measuring. Always test by sitting.
    • Bench wobbling often results from insufficient screws at leg-apron joints. Adding extra screws improves rigidity.

    Watch out

    • Ignoring creaking weakens joints over time causing looseness. Identify noise sources and tighten screws.
    • Re-aligning top board positions requires removing screws; never force alignment as wood may split.
18. 18

    Cleaning and preparation before finishing

    ≈ 10 min

    Clean entire bench with vacuum and tightly wrung cloth to remove wood dust and oils. Fill conspicuous screw head recesses with wood filler; after drying, smooth with #240 sandpaper. Mask any areas not to be painted, particularly ground-contact surfaces.

    Inspect

    No wobble ✓

    InspectSTEP 18 / 20

    Tip

    • Cleaning before finishing determines 80% of finish quality. Focus on cut surfaces to thoroughly remove dust.
    • Fast-drying wood filler that dries in 15 minutes is convenient for screw hole repairs.

    Watch out

    • Applying finish with residual wood dust results in rough surfaces. Always vacuum and wipe in sequence.
19. 19

    Applying protective finish (two coats)

    ≈ 60 min

    Apply indoor wood finish such as Watco Oil or Briwax with a brush over the entire bench. First coat should be light to allow wood absorption; after 24 hours drying, apply the second coat thoroughly. Brush along the grain direction and dry indoors or in low-wind conditions to prevent dust adhesion during drying.

    Paint

    Watco oil / varnish

    PaintSTEP 19 / 20

    Tip

    • A 50mm brush fits the bench size well. Larger brushes do not reach fine areas effectively.
    • First coat is for absorption; second coat fully covers and protects. Two coats are essential for protection.

    Watch out

    • Drying near direct heater airflow causes superficial drying leaving inner wood damp. Allow natural drying.
    • Touching surface before full drying (24 hours) causes fingerprints or dust to adhere.
20. 20

    Completion, installation, and maintenance instructions

    ≈ 20 min

    After full drying of finish (48 hours), place the bench at the desired location. Re-check levelness with a level tool; apply pads to leg bottoms to correct wobbling if needed. For indoor use, reapply oil finish every 3 to 5 years to extend bench life.

    Done!

    Done — nice work!

    DoneSTEP 20 / 20

    Tip

    • Apply felt pads to leg bottoms when placing directly on wooden flooring to protect floor surface.
    • Record maintenance details such as finish date and product name with pencil on bench underside for easier future upkeep.

    Watch out

    • Using bench immediately after finishing risks staining clothing; always wait at least 48 hours.
    • With long use, oil finish wears off and surface becomes dry. Re-oiling every 3-5 years maintains appearance and longevity.

Warnings

• ⚠️Pre-drill pilot holes before driving screws to prevent wood splitting.
