Abstract
A floor sander is disclosed that includes a drum having an outer surface formed from a number of units shaped like the frustrum of a sector, each having a first end receivable in a groove on the outer surface of an inner drum member so that, if the surface of the drum is damaged, one or more units can be replaced individually instead of replacing the entire drum or outer drum surface.
