ABSTRACT:
The invention is in a vacuum driven sander that is appropriate for drywall sanding, that utilizes a vacuum flow pulled therethrough to drive a turbine that includes an adjustable lock mounting through a bearing assembly to an eccentric to turn the eccentric that is connected to oscillate a sanding pad that mounts a section of sanding material, and that vacuum air flow also provides for removing sanded particles off from the sanded surface that are transported through the sander and a connected pipe or hose into a catchment container. The sander housing includes a pole mounting cylinder that projects outwardly from a housing top surface and is ported with equal spaced radial cavities formed around the port, and with a selected pair of cavities to receive each of a pair of stub axles of a pivot collar, providing a first pivot coupling that, along with a second pivot mounting of the collar to the end of a hollow bent tube, provides a universal coupling of the hollow bent tube to the sander body that allows for the pivoting of the sander whereby the sanding surface remains in engagement with the wall as it is moved up and down and across the wall. The hollow bent tube also includes a static discharge electrical connector that receives a female connector fixed to an end of a conductive wire for positioning in a sander pole that is mounted to the bent tube end, with the wire extending the length of the pole wherethrough the vacuum exhaust flow passes and conducts a static electric charge into the vacuum flow.
