  • the continuous marking channel 120 allows for a user to make marks on the workpiece at predetermined angular at predetermined angular offsets from the second workpiece abutment plane 111.
  • no marking channel abutment of the continuous angle marking channel 120 is at a same angular position about the alignment point 122 relative to the second workpiece abutment plane 111 such that no marking channel abutment angularly aligns with another marking channel abutment of the continuous angle marking channel 120.
  • each first marking channel portion 140 is connected to a corresponding second marking channel portion 144.
  • each second marking channel portion 144 is connected to a corresponding third marking channel portion 148 and a corresponding fourth marking channel portion 153.
  • each third marking channel portion 148 is connected to a corresponding fifth marking channel portion 160.
  • each fourth marking channel portion 153 is connected to a corresponding sixth marking channel portion 164.
  • each fifth marking channel portion 160 is connected to a corresponding seventh marking channel portion 170.
  • each sixth marking channel portion 164 is connected to a corresponding seventh marking channel portion 170.
  • each seventh marking channel portion 170 is connected to a corresponding fifth marking channel portion 160 and a corresponding sixth marking channel portion 164.
  • the corresponding connected marking channel portions are angularly offset so as to provide for different predetermined angular marking locations.
  • the marking channel abutments are elongated relative to the dimension of the intended marking tool so as to allow for a radially elongated mark to be formed.
  • a sixth level may be provided.
  • the sixth level would be similar to the first level 130 and radially inward of the fifth level and associated seventh marking channel portions 170.
  • Such a level would have eight marking channel portions that would be similar to the first marking channel portions 140.
  • These marking channel portions would be used for forming desired marks at each 5 degree increment (5°, 15°, 25°, 35°, 45°, 55°, 65°, 75°) relative to the second workpiece abutment plane 111 while the first marking channel portions 140, in this example, are used to form desired marks at each 10 degree increment (e.g. 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°) relative to the second workpiece abutment plane 111.
  • 10 degree increment e.g. 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°
  • first level 130 could be removed in some embodiments and only the second-fifth levels 132, 134, 136, 138, may be implemented where the first and hypothetical sixth level are provided by discrete marking slots.
  • this arrangement allows for 1 degree increment markings to be made with predetermined abutments.
  • the 5 degree increment guide features are provided by discrete marking slots 176 that are radially extending and that are aligned with the alignment point 122.
  • each discrete marking slot 176 is positioned angularly between the first and second seventh marking channel abutments 172A, 172B of the adjacent most seventh marking channel portion 170.
  • These discrete marking slots 176 are equally angularly spaced about alignment point 122 and adjacent discrete marking slots 176 are spaced 10 degrees apart about alignment point 122.
  • the illustrated example also includes three additional discrete marking slots 184, 186, 188 that are aligned at 30°, 45°, and 60° offset from the second workpiece abutment plane 111 as these angular offsets are used more regularly than other angular offsets.
  • these three radially elongated marking slots 184, 186, 188 are, optionally, radially longer than slots 176 to illustrate their more typical use.
  • the second leg 104 includes a second continuous angle marking channel 220 that is substantially identical to the first continuous angle marking channel 120 but that is used for marking at angular positions offset from the first workpiece abutment plane 109.
