Build steps

Measuring and Verifying Installation Space
≈ 15 minMeasure the installation location for the Kids' Workbench (900×600×600mm). Confirm clearance space to pull out a chair and sit comfortably (chair depth + 400mm or more) and traffic flow for dish serving.
MeasureW 900 mmMeasureSTEP 1 / 12Tip
- For a standard dining style, allocate about 600mm width by 400mm depth per person.
- Table height 720mm assumes typical dining chair seat height (420mm) plus 300mm clearance.
- Maintain at least 800mm distance from wall to enable chair pulling out.
Watch out
- A 1200×700mm table is standard for four people but can feel cramped with large serving dishes.
- Overlooking chair backrest thickness during measurement may cause inability to get in or out.

Creating Cut List and Ordering from Home Center
≈ 40 minPrepare nine top boards from 2x6 lumber (38×140×900mm), four legs from 2x4 lumber (38×89×682mm), two long side apron boards (38×89×1124mm), and two short side apron boards (38×89×624mm). Also prepare 60 coarse-thread screws 75mm. Using paid cutting service at home center is convenient.
CutUse the in-store cut serviceCutSTEP 2 / 12Tip
- 2x6 lumber actual size is 38×140mm. Be aware that nominal and actual sizes differ.
- Nine top boards lined up measure 140×9=1260mm. Even with 3mm gaps between boards totaling 24mm, overall length is 1284mm.
- Effective top board width with gaps (9×140 + 8×3mm) is 1284mm, which exceeds 900mm width; adjust quantity or board width accordingly.
Watch out
- Choosing warped or twisted 2x6 boards causes uneven top surface; visually check each piece before purchase.
- Leg length of 682mm equals table height 600mm minus top board thickness 38mm; specify actual measurements when ordering to avoid mistakes.
- 3
Sanding All Materials
≈ 50 minSand in order with #120, #180, then #240 sandpaper. Sand 2x6 top boards carefully — wipe with a wet cloth repeatedly to raise grain, dry completely, then finish sanding with #240 to reduce stain absorption during meals.
Sand#120 → #180SandSTEP 3 / 12Tip
- Avoid splinters as the dining surface contacts food; check by running fingertips over surfaces.
- Wet wiping and drying (water raising) reduces raised grain after sanding.
- Using an orbital sander saves time; consider rental services.
Watch out
- Not chamfering edges causes clothes and skin to catch, especially at child face height.
- Large dust generation during sanding; perform in ventilated areas such as balconies or garages.
- 4
Preassembling Legs and Apron Boards (Frame Construction)
≈ 45 minAttach long and short apron boards to four legs, positioning them 50mm down from leg top ends. Aprons attach outside the legs, fixed with two 75mm coarse-thread screws per joint. Complete a rectangular frame; confirm right angles at all four corners with a carpenter's square.
Build the frameTighten joints firmlyAssembleSTEP 4 / 12Tip
- Attaching aprons outside legs looks better; attaching inside increases strength where top board contacts frame.
- Drill φ5mm pilot holes in aprons before screwing to prevent leg wood splitting.
- Right angles in joints are critical to proper top board fitting.
Watch out
- Driving 75mm screws without pilot holes causes 2x4 lumber splitting.
- Not aligning leg grain and knots direction results in inconsistent appearance.
- 5
Checking Frame Squareness and Diagonal Lengths
≈ 15 minPlace assembled frame on flat floor; confirm all four legs contact floor with no wobble. Measure two internal diagonal lengths with tape measures; confirm discrepancy within 2mm. If out of tolerance, loosen screws and apply clamps from diagonal direction to correct, then retighten screws.
InspectNo wobble ✓InspectSTEP 5 / 12Tip
- Perform measurements on flat surface for accuracy.
- Diagonal difference over 5mm causes top board to seat unevenly; keep within 2mm tolerance.
- Correct any one-leg lift to ensure all legs fully contact the floor.
Watch out
- Ignoring frame distortion leads to warped or ill-fitting top board.
- Low-quality carpenter's squares can have errors greater than 0.5° affecting accuracy.
- 6
Top Board Assembly
≈ 40 minArrange nine 2x6 boards on a workbench aligning grain direction. Place 3mm thick disposable chopsticks between boards for breathing space. From underside, reinforce top board by attaching two 2x4 lumber stringers using wood glue and 45mm coarse-thread screws to unify top board into one panel.
Build the frameTighten joints firmlyAssembleSTEP 6 / 12Tip
- Alternate grain direction (growth ring orientation) of boards to counter warp and cracks.
- Position stringers 200mm inside from edges for aesthetics.
- Confirm 45mm screws do not penetrate 38mm board thickness by measuring length carefully.
Watch out
- Tightly fitting boards without gaps cause swelling and warping from humidity; always provide 3mm breathing space.
- If stringers are mounted crookedly, the top board will distort; verify right angles with square.
- 7
Securing Top Board to Frame
≈ 30 minPlace top board on frame, check balance front/back/left/right with approximately 30mm overhang on all sides. Drill φ5mm pilot holes from apron boards into underside of top board, then drive 75mm coarse-thread screws: four from long aprons and two from short aprons, total of 12 screws.
Build the frameTighten joints firmlyAssembleSTEP 7 / 12Tip
- Overhangs of 30–50mm do not interfere with dining movements.
- Drive screws toward inner side of apron, not center, to reduce wood splitting along grain.
- Screw length must not exceed apron thickness plus 20mm so as not to penetrate top board.
Watch out
- Driving 75mm screws directly risks screw heads protruding on top surface; use pilot holes and countersink.
- Overhangs greater than 50mm cause top board sagging; around 30mm is optimal.
- 8
Surface Preparation for Finishing
≈ 20 minLightly sand entire assembled surface again with #240 sandpaper, then remove dust with damp cloth. For indoor use, apply water-based urethane varnish, Watco Oil, or Briwax. For food contact surfaces, use finishes labeled compliant with Food Sanitation Law for safety.
Sand#240SandSTEP 8 / 12Tip
- Water-based urethane varnish (matte or semi-gloss) offers strong water and heat resistance, suited for dining tables.
- Watco Oil preserves natural wood texture with a soft finish.
- Always test finishes on scrap wood pieces to confirm color before applying to final table.
Watch out
- Glue areas repel finish; sand with #240 to remove glue residue before finishing.
- Residual dust causes rough surfaces on finished coating; clean thoroughly.
- 9
First Coat of Finish
≈ 40 minApply finish evenly with brush on entire surface in order of top board, aprons, legs, then underside. Brush along grain in one direction without streaks. For water-based urethane varnish, wait about 3 hours; for Watco Oil, apply, let penetrate 15–20 minutes, wipe off excess, then dry 2 hours.
PaintWatco oil / varnishPaintSTEP 9 / 12Tip
- Apply thin coats of urethane varnish and perform two coats; thick coats cause bubbles and shrinkage.
- Always wipe off excess Watco Oil; failure leads to sticky surface.
- Dry coatings in dust-free environment.
Watch out
- Applying varnish thickly causes runs and uneven drying resulting in streaks.
- Drying near direct heater airflow causes surface hardening only, leaving layers underneath semi-cured. Use natural drying.
- 10
Sanding Between Coats and Second Coat Application
≈ 40 minAfter first coat fully dries, lightly sand surface with #400 very fine sandpaper (intermediate sanding). Remove dust and apply second coat thinner than first. For three-coat finishes, repeat intermediate sanding once more after second coat to build thicker, more durable finish.
PaintWatco oil / varnishPaintSTEP 10 / 12Tip
- #400 sandpaper is for gentle smoothing of raised fibers only.
- Two coats significantly improve water resistance and abrasion durability; essential for dining surfaces.
- Three coats produce hard, glossy finish typical of commercial tables.
Watch out
- Too aggressive intermediate sanding can remove first coat.
- Touching surface before fully dried causes fingerprints and dust adhesion; strictly observe 24-hour drying.
- 11
Waiting for Finish to Fully Cure
≈ 10 minAvoid placing heavy objects on table for at least 72 hours after finishing to allow full cure. Water-based urethane reaches full cure in about one week. During this time, avoid dining or working on table surface and loosely cover with cloth to keep dust off.
PaintWatco oil / varnishPaintSTEP 11 / 12Tip
- Cure time varies by finish type; always follow manufacturers' label instructions.
- Press gently with fingernail to check if surface does not indent, indicating cure.
- Drying times depend on ambient temperature: 3–4 days in summer, more than a week in winter.
Watch out
- Placing hot pots directly on uncured finish melts and leaves marks.
- Dropping dishes chips finish; be cautious until fully cured.
- 12
Attaching Leg Pads and Final Checks
≈ 20 minAttach felt pads to bottom of all four legs to protect floor from scratches. Move table to installation location and check level with a level tool. Adjust pad thickness if wobbling occurs. Arrange chair and sit to confirm knees do not touch apron boards.
Done!Done — nice work!DoneSTEP 12 / 12Tip
- Use 10mm thick felt pads to absorb floor unevenness.
- Felt pads suit hard floors (wood floors), rubber pads better for tatami mats.
- To correct wobble, adjust one pad to a thinner size as needed.
Watch out
- Using table without pads can cause floor damage due to weight.
- Improper height difference between chair and table (270–300mm clearance) causes poor dining posture.
Warnings
- ⚠️Drill pilot holes before driving screws to prevent wood splitting.
