Thanks for your help Bob,
I anchored the 2x12's on the back wall top plate and on the middle
wall top plate. The house was built in 1965. It's all brick
construction on a cinder block foundation. I have a basement thats
below grade. The wall I'm removing sits in between two floor joists
that run the same direction. I was hoping to get away from posts to
achieve a smooth look.
