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. |
