A saw includes a base having a first length extending generally along a first direction, a table disposed on the base, a saw unit disposed on the base, wherein one of the table and the saw unit is movable relative to the base along the first direction over a range which exceeds the first length. The saw may also include a first stationary rail connected to the base and extending generally along the first direction and a first movable rail engaging the first stationary rail and extending generally parallel to the first stationary rail, the first movable rail being connected to the one of the table and saw unit. Preferably, the first movable rail is slidingly received over the first stationary rail. The saw may also include a first rack disposed on the first movable rail, and a first pinion disposed on the base, wherein the first pinion meshes with the first rack so that the first movable rail moves along the first direction upon rotation of the first pinion. Preferably, the saw further includes a second stationary rail connected tot the base and extending generally along the first direction and substantially parallel to the second stationary rail, and a second movable rail engaging the second stationary rail and extending generally parallel to the first movable and second stationary rails, the second movable rail being connected to the one of the table and saw unit.
