ABSTRACT:
An adjustable sanding device for sanding curved surfaces includes a flexible membrane which serves as a support surface for an abrasive medium. Opposing edges of the membrane are supported and secured to spaced plates interconnected by an adjustable and pivotable linkage which permits the relationship between the planes of the support plates to be varied both angularly and spacially to permit the radius of curvature of the free portion of the membrane to be selectively varied. Locking bolts are provided for securing the relative positions of the plates and linkage in a variety fixed preselected positions. As an alternative, the plates may be pivotally joined along one edge and the oppsoing membrane edges secured to the free edge of each plate with the radius of curvature of the membrane varied as the angle between the plates is varied. A locking linkage is also provided to lock the angle between the plates in a preselected position.
