Step 4. Rest the saw
on the 1 x 4, and cut along the marked line, using the edge of the board
as a guide. Stop the cuts about 1” short of the corners to keep nm
damaging the framing members.
Step 5. Reposition the
1 x 4, and make the remaining straight cuts. Drive nails within 1½” of
the inside edge of the board, because the siding under this area will be
removed to make room for door or window brick moldings.
Variation: For round
windows, make curved cuts using a reciprocating saw or jigsaw. Move the
saw slowly to ensure smooth, straight cuts. To draw an outline for
round-top windows, use a cardboard template.
