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;
Hard Way: Post and remove old 'hanging' header and replace with either 2x8 or 10 header supporting it with 2x4 on either side.
Easy Way 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" +/-
Advice??
