Next, I use one of my favorite
tools—my 7-inch Stanley combination square—set it to 3/16
inch, and scribe the reveal for
the jamb legs and head. At the
intersection of the head and leg
the pencil lines form crosshairs.
From that crosshairs, I measure
down to the top of the plinth
block and that’s the jamb leg
measurement. I cut and install
The bead detail was also
unavailable at my lumber yard,
so I milled it from 1/2-inch stock
using my router and a round-over
bit. To register its length, I meas-
ure outside-to-outside on the
jamb legs then add 1/2 inch.
And, instead of dead-ending it,
I carry the routed edge around
and back to the wall with a return.
