While this is a little off topic, I am guessing that someone in the group
has had some experience in something similar.
I am in the middle (or closer to the end) of a kitchen renovation project,
and want to opened up a wall to enlarge the entry point that had been
shortened up for the previous renovation 20+ years ago. The problem that I
have some across, is that when I had closed up this previously, I had
installed a 2x4 header below a 2x8 header that had been left hanging due to
the removal of wall area on the opposite side of opening. The original
opening was for a rear entryway, but there have been two additional added to
the rear of the house.
This is a bearing wall that supports the second floor and roof and is near
to the corner of the second floor dormer.
My thoughts are this;
Post and remove old 'hanging' header and replace with either 2x8 or 10
header supporting it with 2x4 on either side.
Install a 4x4 or 4x6 under current 'hanging' header, wedge header off new
material to ensure complete contact for load transfer to sistered 2x4 jacks
The opening will be 48" +/-
