A variable camber sanding board includes a generally planar and flexible sanding base, which is adapted to receive abrasive sheet material. A front frame is pivotably linked to a mid handle via a front pivot connection. The front pivot connection includes a pin passing through coaxial bores formed in the mid handle and front frame. A mid handle includes a slotted attachment member which is pivotably secured to a trigger link, forming a middle pivot connection. The trigger link is pivotably secured to a rear handle which is secured to the sanding base via a rear frame. An adjustment pivot connection includes a pin passing through coaxial bores formed in the slot link and rear frame, respectively. A threaded knob assembly, which passes through a bore located in the trigger link and a slot in the slot link can be selectively tightened in a desired position along the length of the slot link.

A sanding block includes a base member with a flat working surface for being positioned against a generally flattened sanding belt. A tightening arm has a first end hinged to a first end of the base member, and a second end movable between an open position away from a second end of the base member, and a closed position latched against the second end of the base member. A first retaining bar is secured to the tightening arm for engaging a first end of the sanding belt, and a second retaining bar is secured to the base member for engaging a second end of the sanding belt. When the tightening arm is opened, the first retaining bar is moved for slackening the sanding belt, and when the tightening arm is closed, the first retaining bar is moved for tightening the sanding belt against the working surface.
