Oak log crotches are very rare

Architectural woodwork

Very difficult to slice, very often with open crotch.

Despite its hardness Oak can be worked well with all tools. Planed surfaces are very smooth. Molding and turning produce good results. Due to the tangential direction of grain there is a risk of raised fibers on the surface when machining Oak crotches

The growth form of the crotch is most problematic for drying. Splitting due to tension is almost not to be prevented.

Oak takes all surface finishes well and treatment presents no problems.

Glue joints are durable. Screw and nail joints hold firmly but can cause wood staining under the influence of moisture.
