Materials

Build steps

1. 1

   Decide Design and Installation Location

   ≈ 30 min

   Decide the design and installation location for the antique-style wooden signboard (700×30×500mm). Draft the layout of letters and patterns at actual size on graph or plain paper. Also decide in advance whether it will be hung or wall-mounted.

   Measure

   W 700 mm

   MeasureSTEP 1 / 9

   Tip

   • Letter size should be readable from a distance; 50mm or larger recommended
   • Avoid tight letter spacing; leave space approximately equal to letter width
   • Overlaying the draft on the board and tracing with carbon paper ensures accuracy

   Watch out

   • Drawing directly on wood makes correction impossible; always prototype on paper
   • Neglecting ventilation and rain exposure at installation location leads to deterioration within a year
2. 2

   Prepare Materials

   ≈ 15 min

   Prepare one solid cedar board (30×500×700mm), two reinforcement battens as SPF lumber 1x2 (19×38×680mm), two stainless steel hanging hardware, ten 30mm coarse-thread screws, wood burning pen (or router), and outdoor paint (e.g., Osmo Color).

   Cut

   Use the in-store cut service

   CutSTEP 2 / 9

   Tip

   • Solid cedar board has rich texture; place face with beautiful knots and grain outward
   • Check for warping on 25mm thick solid boards at purchase; warping causes signboard curvature
   • Wood burning pen (wood burning tool) can be acquired for about ¥1000

   Watch out

   • Avoid plywood; it delaminates outdoors
   • Boards thinner than 15mm risk breaking through when carving letters
3. 3

   Sanding

   ≈ 20 min

   Sand the cedar board sequentially with #120, #180, then #240 grit sandpapers. The signboard surface requires smoothness for carving or writing letters. Chamfer edges 1-2mm to prevent injury. Sand reinforcement battens similarly.

   Sand

   #120 → #180

   SandSTEP 3 / 9

   Tip

   • Surface smoothness affects letter beauty; sand thoroughly
   • Finishing with #240 grit makes wood burning pen lines clean
   • Sand end-grain to help paint penetrate

   Watch out

   • Insufficient sanding causes letters to fade
   • Sanding creates large amounts of dust; perform in ventilated areas like balconies or garages
4. 4

   Transfer Design

   ≈ 20 min

   Transfer full-scale design to the board surface using carbon paper. Darken outlines with pencil and confirm no misalignment. The faint lines remain as guides for burning or carving.

   Mark a line

   Use a try square

   MarkSTEP 4 / 9

   Tip

   • Carbon paper is available at 100-yen shops; press firmly with pencil
   • Make multiple copies of design for retrying if needed
   • Use a level or ruler to check letter horizontality

   Watch out

   • Carbon lines too dark are hard to erase later; transfer lightly
   • Wetting board after transfer causes lines to run; ensure board is dry before painting
5. 5

   Carve Letters (Wood Burning or Router)

   ≈ 60 min

   Trace over transfer lines with a wood burning pen at 300-400°C for 5-10 seconds each or carve grooves 3-5mm deep with a trimmer/router. Test on scrap wood first.

   Drill a hole

   下穴 φ3.5mm

   DrillSTEP 5 / 9

   Tip

   • Burn gently by stroking lightly; pressing hard darkens burn excessively
   • Secure the board when routing; unsteady movement produces jagged lines
   • Outline letters first, then fill inside to create 3D effect

   Watch out

   • Wood burning at flame-producing temperatures risks fire; ensure ventilation and bucket of water nearby
   • Routing too deep can penetrate the board
6. 6

   Attach Reinforcement Battens

   ≈ 25 min

   Attach two reinforcement battens (19×38×680mm) vertically or horizontally on the back of the board using wood glue and four 30mm coarse-thread screws each. They prevent warping and provide substrate for hanging hardware attachment.

   Build the frame

   Tighten joints firmly

   AssembleSTEP 6 / 9

   Tip

   • Position battens corresponding to where hanging hardware will be attached later
   • Drill 3mm pilot holes before screwing to prevent wood splitting
   • Apply wood glue first, then drill pilot holes, followed by screw insertion

   Watch out

   • Unbalanced batten placement cannot prevent warping
   • Check in advance that 30mm screws won’t penetrate board; aim for clamping strength of 25mm board plus 19mm batten = 44mm
7. 7

   Surface Preparation and First Coat

   ≈ 30 min

   Lightly finish with #240 sanding and remove dust. Apply Osmo Color (clear or colored) with a brush. Clear preserves wood grain and accentuates burnt lettering. Let dry naturally for 2-3 hours.

   Paint

   Watco oil / varnish

   PaintSTEP 7 / 9

   Tip

   • Osmo Color is a natural ingredient-based paint retaining wood texture
   • Mask letters with tape if using colored paint
   • Use UV-protective paint for outdoor use to prevent fading

   Watch out

   • Thick paint hides lettering; apply thinly
   • Painting in direct sunlight dries surface alone leaving the inside semi-dry; choose shade or cloudy weather
8. 8

   Second Coat

   ≈ 30 min

   After the first coat dries, lightly hand-sand with #400 and remove dust. Apply a thin second coat to form a solid protective film for outdoor use. Allow drying for at least 24 hours.

   Paint

   Watco oil / varnish

   PaintSTEP 8 / 9

   Tip

   • Two coats greatly improve resistance against UV and rain
   • Hand-sanding with #400 should only smooth fibers
   • Place in dust-free area while drying

   Watch out

   • Rain before drying causes paint to run; check weather forecast before painting
   • Thick second coat buries letters
9. 9

   Attach Hanging Hardware and Installation

   ≈ 30 min

   Attach two stainless steel hanging hardware units to the top edge aligned with reinforcement battens, securing each with four 30mm coarse-thread screws. For wall-hanging, use chains or wire on wall hooks; for direct wall mounting, screw into wall studs.

   Done!

   Done — nice work!

   DoneSTEP 9 / 9

   Tip

   • Select stainless steel hardware; iron rust causes stains
   • Chain length allows angle adjustment; match design preferences
   • Locate wall studs using a stud finder when fixing to walls

   Watch out

   • Weak hardware risks fall due to weight and wind load
   • Drywall alone cannot support load; always fix into studs

Warnings

• ⚠️Applying wood preservative for outdoor use is essential (reapplication recommended annually)
• ⚠️Use stainless steel screws (iron screws will rust)
• ⚠️Drill pilot holes before screwing to prevent wood splitting
