CROSSCUTTING s cutting with the grain is synonymouswith theuseof therip fence, so crosscuttingis definedby the device usedto makethe cut: the miter gauge. The generaltechniquefor making a crosscut,asshownbelow,beginswith correct hand placementto keep the workoieceboth flush on the tableand firmly againstthe miter gauge.The workpieceis fedinto thebladeat a steady rate.As with ripping, makesurethat scrappiecesdo not pileup on thetable, andkeepboth handsout of linewith the blade.Also,keepthe rip fencewellback from the bladeto preventany cut-off

part of the workpiecefrom becoming trappedbetweenthebladeandfenceand kickingback. To reducetheamountof sandingyou will needto do later,rememberthat the slowerthe feed,the smootherthe cut, thebladebreaksthrough especiallywhen the workpieceat the end of the cut.

MOLDINGS i\ tablesawismorethanjusta machine A to cutwood.With thepropersetup, a sawbladecanserveasa milling device to cut covemoldings(pagea3).And by replacingthe sawbladewith a molding headanddifferentsetsofcutters,a plain boardcanbecomeanelaborate molding. Pieces ofwood canbe shapedseparately and then glued togetherto form an impressivearrayof designs.The results rangefrom crownmoldingsfor a cabinet to decorativedoor and frame moldings-made at a fractionof the costof their store-boughtcounterparts.

Moldingcuttersaresoldin setsof three,which areinstalledin a molding headand then fastenedonto the arbor. By passingthe wood overthe cutters repeatedly andraisingthemoldinghead slightlyeachtime,a patternis cut into thewood.Themorepasses, the deeper theinscriotion. Like a dado head,a molding head requiresits own tableinsertwith a wide openingto accommodate the width of the cutters.A woodworkercanmakean insertfor eachsetofcuttersby placinga blankoieceof wood in the tableinsert

Moldingheadshavea reputationfor beingdangerous and while thereare alwayshazardsinvolvedwhen usinga tablesawthereis little risk whenmolding headsareusedwith propercare.A fewpointsto keepin mind: Do not cut moldingson shortlengthsof wood;a pieceshouldbe at least12incheslong. Also,do not cut moldingson narrow strips;cut themoldingson piecesat least 4 incheswideandthenrio to width.

SETTINGUP tl- h. setupprocedures describedon I thesepagesmay seemlong and involved,but do not neglectthem. Without careful maintenance,your machinewill not cut with orecision. A problemwith manyradialarmsaws is that adjustmentsareleft too loose, playin movingparts allowingexcessive and resultingin sloppycuts. Ideally, clampsshouldlock tight and sliding mechanisms shouldbeneithertoo loose nor too snug. Adjustthe table (right),the clamps (below)and the sliding mechanisms (page54)beforeeverynewproject.Each time you usethe saq clearthe sawdust flom the gapbetweenthe tableand the fence,and clearthe trackunderneaththe arm. Periodically, touchup the moving partswith a silicone-based lubricant.It is alsoimportant to squaretheblade(page 55)andcheckfor heeling(page56). Beforeusingyour sawfor the first time, you will needto install a fence and an auxiliarytable(page5Z).To test your adjustments, crosscuta l2-inchwide board and a 1-by-3standingon edge,then checkthe cut endswith a carpenter's square.

SAFETY I lthoughthemanymovingpartsof A a radialarmsawmakeit oneof the mostflexible machines in theworlshop, theyalsomakeit oneof themostdangerous. Crosscutting-the mostbasicuse of the saw-requiresyou to pull the bladetowardyourbody.Anddepending on thesettingof the arm,yokeand motor,thebladecanmakeitsapproach fromseveral directions andangles. Wth everycut,youhaveto anticipate exactly wherethebladewill endup. Whenyourip boards ona radialarm saw,you feedtheworkpiece into the

blade,and this demandsevengreater careand concentration. The chances of kickbackarehigh enoughthatthesafety devicesillustratedbelowandat rieht are absolutelyessential. Armedwith a thoroughknowledgeof the machine'soperation,you canapproachit with a healthymixtureof caution andconfidence-asyou wouldwith anyotherpowertool in your workshop. Make certainthat all the clampsfor holding the arm, yoke, carriageand motor in positionarelockedwhenever you turn on the saw Also be sureto

familiarizeyourselfwith the owner's manualfor your machine,and takethe time to setup themanysafetyaccessories and blade guardsthat are available. Remember, however,that no accessoryor guardcancompensate for a lackof careful attentionand commonsense. For anycut,keepyour fingersat least 6 inchesawayfrom the blade;usepush sticlaor featherboards wherepossibleto feedor hold theworkpiece.Wearsafety glasses at all times,anda maskor respiratorandhearingprotectionfor extended useof the saw.

SETTINGUP he band saw has a reputation amongsomewoodworkersasa relativelyimprecisecutting tool. And yet bandsawsareroutinelyusedin industry to cut veryhardmaterialssuchasmetal to very close tolerances.The fact remains,however, that thetool canonly be madeto cut straightedgesand precisecurvesif it is kept finely tuned. The ideal is for the blade to cut squarelyinto the workpiece,producing a smooth,accurateresult.But thepeculiaritiesof bandsawgeometrycanmake this idealdifficult to achieve.After bending aroundthe machine's wheelsat 35

milesperhour,a sectionof theblade muststraighten outbythetimeit reachesthesawtablea splitsecond later.

But evenwithinthisrelatively narrowspectrum,choosing thebestbladeforthejob isnotalways straightforward.

If a deadend seems markcuttinglineson both unavoidable, sidesof the workpiece.Occasionally, startinga cut on onesideof a workpiece and finishingit on the otheris the only wayto makea cut.

CUTTINGDUPLICATEPIECES methodfor producing I n effective A multiplecopiesof thesameshapeis to fastenlayersofstocktogetherandcut thepiecesin oneoperationwith a techniqueknownasstacksawing.Not only is it fasterthancuttingall thepiecesseparately;it alsoensures that eachpieceis a precise copyofthe originalpattern.The methodis possible because of theband

saw'suniquecapacityto cut throughvery thickwood.With a 6-inchdeothof cut a bandsawcancut*rou$ asmanyasei$t pieces of %-inchplywoodin a singlepass. Tobond thelayersof woodtogether in preparation for thecut,somewoodworkersdrivenailsthroughthe waste area;othersuseclamps.Bothmethods, however, canbe hazardous ifthe blade

accidentally strikesa nail or a clamp.A saferwayis to usedouble-sided tapeto hold thepiecestogethertemporarily. A stopblockon thesawtablewill also savetime when you are crosscutting repeatedly to turn out duplicatepieces. With the setupshownbelow,you can speedthejob of cuttinga cylinderinto identicalslices.

Thestandard spindleismatedto a chuckwith aVz-inchcapacity, whichmeansthatitsjawscanaccept shanks ofdrill bitsandaccessories upto Vzinchindiameter. Otherspindles allow ttredrill press to accept routerbits,moldingcuttersandmortisingattachments. The columnis helduprightby a heavybase,usuallymadeof castiron.

Sincethetableof a drill presscanbe positioned anywhere alongthelengthof thecolumn,floormodelscanhandle longerworkpieces. However, youcan-to someextent-overcome thelimitations of a bench-model drill presssimplyby swingingaround the head of the machine.

IOINTING n. of thefirstrulesof jointingis A that a workpiece shouldalwaysbe \,/ fed acrossthe cutterheadso that the knivesarecuttingwith thegrain,In this wayyouwill getthesmoothestcut while reducingtheriskof splinteringor kickback.Ifthe grainchanges directionin a workpiece, feedthestocksothatmostof the cut is followingthegrain. Thesequence for jointingoperations shoulddependon the wood you are

using.Forroughlumber,joint thefaces first (page 134),then do the edges (below). Forwoodon whichboth faces jointingthe havealreadybeensurfaced, is edges usuallysufficient. In general, seta cuttingdepthof 7s inchfor softwoods or '/reinchfor hardwoods.Youcanusuallyjoint theedges by hand,but alwaysusea pushblockto face-joint.Whatever thedepthyouselect, checkthe settingbeforemakingthe first

Then,placea boardflushon theoutfeed gapbetween table;the theboard's edgeand theinfeedtablewill equalthedepthof cut. If mostof yourjointinginvolves working with boardedges, avoiddullingthe samenarrowsegment of yourknivesby routinelymovingthefenceoverslightly to evenlydistributethewear.
