In orderto fit properly,crown moldingmustbe com-
pound miteredwith extremeaccuracy.
The two contact surfaceson a piece ofcrownmolding
that fit fiat againstthe ceilingand the wall ofa room
are at anglesthat, when addedtogether,equal
exactly90°. Most crown moldinghas a top rear angle
(the sectionthat fits flat againstthe ceiling)of 52° and

To usethis methodfor accuratelycutting crown
moldingfor a 90° insideor outsidecorner, laythe
molding withitsbroad backsurface fiaton the miter
table and againstthe fence.
When settingthe bevel and miteranglesfor Com-
poundmiters,rememberthat the seffings are interde-
pendent;changingone angle Changesthe otherangle
as well.
Keep in mindthatthe anglesfor crown moldings are
veryprecisea_nddifficultto set. Since itisveryeasy
for these anglestoshift,all settingsshouldfirstbe
tested on scrap molding.Also most wallsdo not have
anglesofexactly90°, therefore, youwillneed to fine
tuneyour settings.
