1. A method of operating a sanding device with a plurality of mobile pressure devices, each mobile pressure device of the plurality of mobile pressure devices is aligned laterally along a rail and each mobile pressure device of the plurality of mobile pressure devices is configured to move laterally relative to all of the other mobile pressure devices of the plurality of mobile pressure devices along the rail, the method comprising
laterally displacing at least one mobile pressure device of the plurality of mobile pressure devices,
individually oscillating each mobile pressure device of the plurality of mobile pressure devices in a lateral direction independent of all of the other mobile pressure devices,
moving upward the at least one mobile pressure device of the plurality of mobile pressure devices in a direction perpendicular to the lateral direction such that oppositely mounted mobile pressure devices of the plurality of mobile pressure devices opposite to the at least one mobile pressure device can move laterally directly under the at least one mobile pressure device,
holding the at least one mobile pressure device with an offset attachment so that the oppositely mounted mobile pressure devices can move laterally directly under the at least one mobile pressure device.
