Product Details
One of the hardest timbers on the planet, dressed and ready to fret. Gidgee — Acacia cambagei — from the inland Queensland and NSW mulga scrub, with the density and natural oils that put it in the same fret-life band as African ebony.
What it is. A slow-growing arid-zone acacia, the heartwood deep chocolate to near-black with occasional fine waver in the grain. Self-lubricating oils carry through the section, which is why no top coat is needed for it to wear well under strings.
What you’d make with it at 15×70×800mm.
- Six-string electric or steel-string fingerboard — standard width, scale lengths to 25.5″
- Classical fingerboard for a builder choosing density over imported ebony
- Mandolin or short-scale fingerboard with offcuts for inlay accents
- High-wear bridge plate or saddle stock for a darker hardwood acoustic build
Working notes
- Density: ~1,100 kg/m³ — very dense, ranks among Australia’s hardest commercial timbers
- Hardness: ~12 kN Janka — extreme; sharp tooling and patient feed rates are the price of working it
- Grain: Tight, interlocked, occasional fine figure — holds fret slots cleanly and radiuses to a glossy surface
- Surface: Supplied with a true reference face — ready to mark out fret slots and radius
- Working: Carbide tooling is mandatory; HSS dulls quickly. Slot with a sharp fretsaw or CNC; epoxy or fish glue for bonding (the oils resist PVA)
- Finishing: Maintenance only — a wipe of lemon oil at string-change is plenty
What luthiers say about it. Australian builders have reported fret-wear on Gidgee fingerboards behaving more like ebony than rosewood — a comparison that’s been consistent in Australian Wood Review instrument features and the local steel-string builder community for two decades.
The stack it came from. Gidgee grows slowly and dries slowly — the boards on this listing have rested for years before being dressed to fingerboard thickness. Once it goes, the listing closes.
