Making a taper on a piece of wood is difficult with only a table saw and is dangerous attempting free-hand. The DCT Taper Gauge Jig Tool Kit Set for Tapering (Angle Cutting) Wood Tapered Legs and More allows you to make taper or angle cuts safely and accurately on any radial-arm or table saw. You get a good cut quality from a table saw and the benefit of a straight cut from the taper jig. The handle and work stop can be assembled to either arm and changed as needed for all left or right hand applications. It is constructed from sturdy aluminum and adjusts to a maximum taper of 15 degrees (3 inches per foot). This package includes jig legs, a scale, locking bracket, work stop, handle, assembly hardware, and assembly instructions. Wood and saw required, not included.
