Arcs and Circles

With the entire fence assembly removed, carefully position the jig for desired
It is important with the arc and circle shapes that the workpiece, prior to being shaped, must be roughly cut to the desired size and curve of the finished piece. Make sure that the jig curve matches exactly the workpiece curve. At all times keep the workpiece firmly in contact with the jig while the cutter is cutting the stock.
Never perform this type operation without a ring guard, safety collar or similar safety device over the cutterhead.
Enclosed Edge Shaping
An enclosed workpiece edge is shaped in the same manner as an outside contoured edge except that a starting pin is not required as shown in Figure 48.
Note: If the whole edge is to be shaped, the operator must use a pattern.
Position the workpiece on the table before starting the motor. The operator must do the entire shaping cut by pushing (feeding) the workpiece into the cutter(s).
Enclosed edge shaping is extremely dangerous. The operator must be aware at all times of the direction of feed. Never perform this type operation without a ring guard, safety collar or similar safety device over the cutterhead.
With a firm grip, ease the edge into the cutter(s) until stopped by the collar as shown in Figure 48.
Continue to push straight in while feeding and turning the workpiece at the same time until the cut is finished. Turn off the motor and do not remove workpiece until the cutters have completely stopped.
Never perform enclosed edge shaping if there is less than two inches of workpiece material all around the opening. Never perform enclosed edge shaping if the workpiece opening is smaller, in any direction, than twice the diameter of the cutter(s).
