Description: |
| The primary claim of this patent concerns a centering point which provides an accurate start while cutting a tenon on the end of a spoke. Once the cut has commenced until the end of the tenon contacts the stop (E), it is backed off slightly and the centering point withdraws, allowing the tube/body of the hollow auger to guide the remainder of the cut. |
