between uncut joists
(Figure15). The measurement should be done perpendicular to
the joists.
STEP 2
Cut to size 4 headers. For that purpose use timber similar in size
to existing joists.
STEP 3
Position one header at the end of the cut out joist (Figure16). It
must fit tightly between the uncut joists. If needed use a hammer
to set the header in the appropriate place.
STEP 4
Square the header to one joist and drive 3 nails (16d) on both
ends and to the cut joist (Figure 16).
STEP 5
Position the second header in front of the first one and nail it
(Figure 17).
STEP 6
Repeat steps 3-5 in order to install headers at the other side of the
ceiling opening.
