This kit is equipped with helpful tools for completing any project, from cutting straight lines to perfect circles and precise angles. The Taurus 3 Accessory Kit includes the following: Straight Edge: This tool gives the ability to cut straight lines, which would ordinarily be very difficult, with your ring saw. 30/60 Degree Cutoff Triangle: Works in unison with the straight edge to cut a 30 or 60 degree angle. 45 Degree Cutoff Triangle: Works in unison with the straight edge to cut a 45 degree angle. Bevel Edge Maker: This works in unison with the straight edge to make perfect 45 degree beveled edges. Circle Maker: This item works on any location of the work surface and helps to create perfect circles. Lamp Wedge: Use the lamp wedge to put a 30 degree bevel on the edge of a finished piece. This will allow the pieces to fit together more tightly, allowing for a smaller, stronger solder joint.
