Phase 4 · Months 6–8

Wood as an Artistic Medium

Phase Objective: Break free from straight lines and explore the organic, sculptural side of woodworking.

MODULE 11

Sculpting and Shaping

11.1

Shaving Tools

Spokeshaves shape convex and concave curves — flat-sole for convex, round-sole for concave hollows. The drawknife is the fastest wood-removing hand tool: pulled toward the body with two handles, it removes thick shavings in seconds. Rasps (especially Auriou cabinet rasps) work like a coarse file but leave a surface that can be refined directly to finishing grade without sandpaper.

11.2

Power Carving

Angle grinder carving disc attachments (King Arthur's Tools, Kutzall) remove material faster than hand tools — useful for chair seats, organic sculpture, and large hollows. Die grinders with carbide burrs work the same principle at smaller scale. Power carving requires a full face shield and heavy leather gloves.

Common Mistake Always secure the workpiece firmly. The rotating disc can grab and rotate the piece violently.

MODULE 12

Bending Wood

12.1

Steam Bending

Steam softens the lignin holding wood fibres together, allowing them to compress and stretch. Build a simple steam box from PVC pipe and a wallpaper steamer. Steam time: approximately 1 hour per 25mm of thickness. Bend immediately after steaming — you have 30–60 seconds before the wood cools and stiffens. Use a bending strap on the outside of the curve to prevent fibres from breaking in tension.

12.2

Bent Lamination

Resaw a board into 3–6mm strips. Glue all strips simultaneously and clamp over a curved mould or form. When glue cures, the assembly holds the curve permanently — less springback than steam bending and capable of tighter radii. Bent lamination requires no steaming apparatus and is repeatable exactly.


MODULE 13

Veneering and Marquetry

13.1

Vacuum Pressing

Highly figured burls and exotic veneers are too unstable to use as solid wood. Vacuum pressing laminates them to stable MDF or plywood substrates. A vacuum bag pulls the veneer flat against the substrate with 100kPa pressure — equivalent to 100kg per 100cm² — ensuring full contact across irregular surfaces.

13.2

Inlay

Routing a precise channel and inlaying a contrasting material — another wood species, brass, ebony, or mother-of-pearl — adds decorative detail without compromising structural integrity. The channel must be routed to exact depth (1.5–2mm) with vertical walls. The inlay is glued in, cured, then planed or scraped flush. String inlay around a tabletop edge is one of the most classic furniture embellishments.


🏆 Phase 4 Milestone Project

The Sculpted Stool

A three or four-legged stool with a deeply power-carved ergonomic seat. Legs are shaped dynamically using a spokeshave or drawknife, and attached with wedged through-tenons visible on the top face of the seat.

Success criteria: Seat is visibly concave and ergonomically shaped — not flat with a chamfer. Legs are tapered and shaped, not square-cut. Wedged through-tenons are tight and wedges show on the seat surface. Stool does not rock on a flat surface.
