I remember my Dad, who was a school superintendent in small town districts in Missouri, working one summer with the school janitor to refinish the maple floors in the school gymnasium, and then bringing the machinery home one weekend and doing the floors in the living room area of the house we were renting at the time. That is physical, intense work horsing those sanders around all day! You indeed do beautiful work. Just curious, what type of finish (varnish, polyurethane, something else?) do you apply, and what is your application method?
