13Collar PositioningCollars may be positioned above, below, orbetween two cutters:1. When using the collar below the cutter,figure 14, the progress of the cut can beobserved at all times. A disadvantage ofthis method is any accidental lifting of thework will gouge the wood and ruin theworkpiece.2. Using the collar above the cutter, figure 15,offers the advantage of the cut not beingaffected by slight variations in the stock'sthickness. However, the cut is not visibleduring the operation. Another advantage isaccidental lifting of the work piece will notgouge the work piece. Simply correct themistake by repeating the operation.3. The collar between cutters method, shownin figure 16, has both the advantages anddisadvantages of the first two methods.This method is used primarily where bothedges of the work are to be shaped.Starting Pin WARNINGUsing the starting pin should only beattempted by advanced users! If you havenever used this method before, it isrecommended you get training from aqualified person who is knowledgeable instarting pin shaping!Failure to comply may cause serious injury!The starting pin is placed in one of the threadedholes in the table:1. Work should be placed in the first positionusing the guide pin as support, as shown infigure 17. Then swing the work into thecutter as shown in the second position. Thework will now be supported by the collar andstarting pin.2. After the cut has been started, the work isswung free of the starting pin and rides onlyagainst the collar as shown in the thirdposition in figure 18. Always feed againstthe action of the cutter.
