26Crosscutting should never be done freehand norshould the fence be used as an end stop unlessan auxiliary block is clamped to the front of theblade area such that the cutoff piece comes freeof the block before cutting starts (Figure 42).Figure 42Length stops should not be used on the free endof the workpiece in the cutoff area.Do not crosscut workpieces shorter than 6".Before starting a cut, be sure the miter gauge issecurely clamped at the desired angle. Hold theworkpiece firmly against the table and backagainst the miter gauge. Always use the sawguard and splitter and make sure the splitter isproperly aligned.For 90 degree crosscutting, most operatorsprefer to use the left-hand miter gauge slot.When using it in this position, hold the workpieceagainst the gauge with the left hand and use theright hand to advance the workpiece. Whenusing the right hand slot for miter and compoundcrosscutting so that the blade tilts away from thegauge, the hand positions are reversed.When using the miter gauge, the workpiecemust be held firmly and advanced smoothly at aslow rate. If the workpiece is not held firmly, itcan vibrate causing it to bind on the blade anddull the saw teeth.Figure 43To improve the effectiveness of the miter gaugein crosscutting, some users mount an auxiliarywooden extension face (with a glued-on strip ofsandpaper) to the miter gauge as shown inFigure 43.Provide auxiliary support for any workpieceextending beyond the table top with a tendencyto sag and lift up off the table.Stop rods can be used in the holes provided inthe miter gauge for repetitive work of equallength. Do not use a stop rod on the free end ofa workpiece. It should be used on the side of themiter gauge opposite the saw blade.Have the blade extend about 1/8" above the topof the workpiece. Exposing the blade above thispoint can be hazardous.Bevel and Miter OperationsBevel Cut – A bevel cut is a special type ofoperation where the saw blade is tilted at anangle less than 90 degrees to the table top(Figure 44). Operations are performed in thesame manner as ripping or crosscutting exceptthe fence or miter gauge should be used on theright-hand side of the saw blade to provideadded safety in avoiding a binding actionbetween the saw blade and the table top. Whenbeveling with the miter gauge, the workpiecemust be held firmly to prevent creeping.Figure 44Crosscut – Crosscuts made at an angle to theedge of the workpiece are called miters(Figure 45). Set the miter gauge at the requiredangle, lock the miter gauge, and make the cutthe same as a normal crosscut except theworkpiece must be held extra firmly to preventcreeping.Note: When making compound miters (withblade tilted) use the miter gauge in the righthand slot to provide more hand clearance andsafety.
