Olson FretLite a brilliant solution for fret work! FretLite solves the problem of every scroll saw user-seeing the pre-drilled pilot holes on the bottom of the workpiece while inserting the blade. With the intense light shining up through the table, blade insertion is faster and easier. This reduces project time and saves money for fret sawyers who may otherwise have difficulty seeing holes clearly, especially when working in dark shades of wood or with very fine saw blades.
