Workability
Sawing/Machining: Hickory
species’ density makes it difficult to season, machine and work with
hand tools.
Sanding: Difficult to sand because of density, and
because light color makes sander marks show more than on darker woods.
Nailing: Good holding ability; prone to splitting.
Finishing: No known problems.
