I have searched and searched for this, but haven't really found anything other than people explaining what balloon framing is. Anyway, I have gutted out my 1890s two story farmhouse and want to remove the 1x4 ribbon under the 2nd floor joists. The joists are face nailed to the studs and have the 1x4 under them. I have to sister the joists to meet code, the ribbon isnt completely let in (or uniform) so drywalling is going to be a pain, and I have to fireblock it. Any suggestions? I was thinking of making a header with 2' cripple studs that would support the joist and fireblock at the same time.
