Juglans nigra

Trade Names

Walnut Crotch

Latin Names

Juglans nigra

Origin

North America (Juglans nigra) and very seldom in Europe (Juglans regia).

Range

Branch forks of Walnut trunks.

Uses

Architectural woodwork, upright and grand piano production, gunstocks.

Properties

Lengths over 1 m very seldom, often open in the crotch.

Machining

The wood is easy to work with all hand and machine tools. Walnut is excellent to mold. The direction of growth must be observed to prevent fibre pick-up.

Seasoning

Drying has to be carried out with particular care where the Walnut Crotch is concerned so that no tension checking occurs in the crotchy part.

Finishing

The very smooth wood takes all stains well particularly water and nitro stains. The wood polishes well when fillers are used.

Jointing

Joints using screws, nails and glue are easy to produce and are of normal tensile strength. However, alkaline glues can cause reaction stains.
