Our Circle Jig Attachment simply slides onto the stainless steel guide shafts in place of the Edge Guide body. It transforms the assembly into aCircle Jig with a  6" to 48" diameter capability. It includes a 1/4" stainless steel Center Pin. There is a 3/8" long spike on the end of the pin that measures 5/32" in diameter which taps firmly into any 1/8" pilot hole for a remarkably secure center position. The Circle Jig Attachment features it's own micrometer unit and is used for a number of other Micro Fence functions as well (the Ellipse Kits and Clamp Interfaces). Each Circle Jig comes with an aluminum straight-line fence for parallel dadoes and an eight-page instruction booklet. 

When purchased as the Circle Jig Attachment, the package does not include any Mounting Bar assembly. This is included for whatever router you specify when you purchase the Circle Jig Complete or Micro Fence Edge Guide.

We highly recommend using the Stabilizer Bar accessory for virtually any set-up with the Circle Jig tools. It maximizes rigidity and affords the most prescise cutting possible. For larger radii, our recommendation is to employ the Stabilizer Bar/Stabilizer Bar Levelers every 24" - 30" to support the stainless steel rods parallel to the work surface.
