How to assemble a wooden mechanical model kit
Laser-cut wooden mechanical kits press out of plywood sheets and build into working models with gears, rubber-band drives or clockwork. They need no glue, but parts must be removed cleanly and fitted in the manual's numbered order, and moving parts need a little wax to run smoothly.

Parts to check first
Before you start, lay everything out on a soft surface (the flattened box works) and check it against the parts list in your manual.
- Plywood sheets with laser-cut parts
- Axles and rubber bands
- Instruction booklet
- Spare parts sheet
Step by step
Step 1: Read the booklet through first and find which sheet each step uses.
Step 2: Press out each part only when its step comes up, cutting the small holding tabs with the knife instead of snapping them.
Step 3: Sand off any burr left by the tabs, especially on gear teeth and axle holes.
Step 4: Push the parts together gently; if a joint is tight, sand it lightly rather than forcing it.
Step 5: Rub wax on gear teeth and axles as the booklet shows, before they are enclosed.
Step 6: Test each gear train by turning it by hand before closing it in.
Step 7: Fit the drive (rubber band or spring) last and run the model slowly at first.
Common mistakes
- Pressing all the parts out at once and losing track of numbers.
- Forcing a tight joint and splitting the thin plywood.
- Skipping wax on gears, so the model jams.
Safety notes
- Cut away from your fingers with the craft knife.
- Small parts are a choking hazard for young children.
This is general guidance for this type of product. Your product's own manual comes first: follow its order, fittings and torque values where they differ from this page.
