Jobillo, also known as goncalo alves or tigerwood, is typically a medium reddish brown with irregularly spaced streaks of dark brown to black and the color tends to darken with age. Jobillo is generally not too difficult to work, despite its high density. Figured pieces with irregular grain can pose a challenge in planing and machining operations. Jobillo can also have a moderate blunting effect on cutters. The wood is very resistant to moisture absorption, which can make it difficult to glue. Jobillo turns and finishes well. 1.5" x 1.5" x 12" Spindle Turning Blank.
