Quarter-Sheet Sandpaper Cutting Jig
A slotted bench jig that cuts a standard 9 x 11 in (229 x 279 mm) sandpaper sheet into exact 1/2, 1/3 and 1/4 sheets for palm and orbital sanders: register the sheet against the 6 mm fence and run a utility blade down the 3 mm guide groove at 93.1 mm (thirds), 114.3 mm (4.5 in) or 139.7 mm (5.5 in) from the fence face. 154 x 100 x 15 mm open-frame plate with a perpendicular squaring fence, dot markings to identify each groove, and two 4.5 mm holes for #8 wood screws so it can be fixed to the bench.
