Convert a floor sanding buffer to a triple disc machine

[ruckle999]

looks great. would it not work better if the heads were freewheeling

@ruckle999 a very intelligent comment, thank you, no it would not be as effective if the discs were freewheeling. some of the friction would be lost as the discs give way to the floor. it would take longer to sand with freewheeling discs. thanks again, for intelligent question.
