Quick-change sanding drum

A sanding drum assembly comprising:

• a base portion;
• a plurality of feet extending upwardly from the base portion along an axis, each of the plurality of feet including a lower foot portion and a movable upper foot portion above the base portion, the plurality of feet movable between a first configuration whereat the upper foot portions define a first outermost circumference radially outwardly from the axis and a second configuration whereat the upper foot portions define a second outermost circumference radially outwardly from the axis, wherein the second outermost circumference is larger than the first outermost circumference;
• at least one elastic friction member extending about the plurality of feet, the at least one elastic friction member expandable by the plurality of feet from a first outer perimeter to a second outer perimeter as the plurality of feet moves from the first configuration to the second configuration;
• and
• an actuator having a cylindrical head portion having a sidewall parallel to a longitudinal axis of the actuator and operably contacting an inner portion of each of the plurality of feet such that the actuator side wall applies a force to the inner portions to force the plurality of feet from the first configuration to the second configuration, wherein
• in the first configuration the lower foot portions substantially define a first maximum diameter and the upper foot portions substantially define a first minimum diameter, and the first maximum diameter is greater than the first minimum diameter.
