Red oak, sepele, and walnut. All kiln dry materials I had in the shop. Did split the red oak board to orientate the grain for the spoke shave. The walnut was used for the seat. It is a frame and panel seat, mortised and tenon joinery, made perhaps thirty years ago. I originally was going to make a Windsor armchair project illustrated in “The Art of Woodturning” by William W. Klenke (full of great projects). I never figured out how to achieve the rush seat without compromising it to much. So long story short, a “pleather” seat and a resting place I intend to keep in the shop. Stained and oil-varnish finish.
