At a glance: Stair Finishing Tools

A stair finishing tool is a woodworking tool that incorporates both a right angle and an acute angle in its design. The jig is easily transported due to its small size and light weight. Precise measurements are required to layout the diagonal locations.

This jig uses a zero reference line from which the rise and tread are measured. The upper part of the jig is a right triangle with a round over overhang. The template allows for a tight fit of the tread into the stringer in the overhang section. The bottom of the jig incorporates an acute angle. This tapered angle allows a space for a wedge to fit against the back side of the vertical and the horizontal plane of the stringer. This jig can be used to lay out different rise (vertical) and tread (horizontal) widths. The jig is used with a plunge router and a bushing guide. The router plows out a precise groove into the finished product that allows all the parts to fit together.
