It’s had an inch by a yard notch cut out of it for a massive piece of fireplace slate so I think I have to go back about 5 foot for full thickness. I could sister it but does anybody know if I shouldn’t try to cut out the offending section and marry it with a steel plate either side, about 6” x 24” with through bolts or is that mental thinking?
    it’s about 2” from the wall it spans.

    Just coach screw and bolt a new piece alongside with a four foot overlap to sit on the outside wall. By the way it's a joist, not a rafter.
