CUTTING CROWN MOLDING
Thiscompoundmitersawdoesanexcellentjobofcutting
crownmolding.Ingeneral,compoundmitersawsdoabet-
terjobofcuttingcrownmoldingthananyothertoolmade.
Inordertofitproperly,crownmoldingmustbecompound
miteredwithextremeaccuracy.
Thetwocontactsurfacesonapieceofcrownmoldingthat
fitflatagainsttheceilingandthewallofaroomareatangles
that,whenaddedtogether,equalexactly90°.Mostcrown
moldinghasatoprearangle(thesectionthatfitsflatagainst
theceiling)of52°andabottomrearangle(thesectionthat
fitsflatagainstthewall)of38°.
LAYING MOLDING FLAT ON THE MITER TABLE
See Figure 31.
Tousethismethodforaccuratelycuttingcrownmoldingfor
a90°insideoroutsidecorner,laythemoldingwithitsbroad
backsurfaceflatonthemitertableandagainstthefence.
Whensettingthebeveland miter angles forcompound
miters, rememberthat the settings areinterdependent;
changingoneanglechangestheotherangleaswell.
Keepinmindthattheanglesforcrownmoldingarevery
preciseanddifficulttoset.Sinceitisveryeasyforthese
anglestoshift,allsettingsshouldfirstbetestedonscrap
molding.Alsomostwallsdonothaveanglesofexactly90°,
therefore,youwillneedtofinetuneyoursettings.
Whencuttingcrownmoldingbythismethodthebevelangle
shouldbesetat33.85°.Themiterangleshouldbesetat
