           •  Check the squareness with a try square.

              Fig 2                                               Fig 3



















           •  Set Jenny caliper to 74 mm using steel rule.
           •  Draw parallel lines of 74 mm to side (B) and (C)
           •  Punch the marked line using dot punch and ball pein hammer.
           •  Set and file sides (D) and (E) to 74mm and maintain squareness to all other sides.

           •  Maintain (D) and (E) parallel to side (B) and (C) (Fig 4)
           •  Check the dimensions with a steel rule and squareness  with a try square.
           •  File surface (F) and maintain the thickness of 9 mm parallelism to side A.
           •  Remove sharp edges. Apply little amount of oil and preserve it for evaluation.
