| Most of the knob and tube I have seen is a single wire ran thru a tube placed in a hole drilled through the ceiling or floor joists. The hole is not large enough to get romex through.
You may be able to change the direction of the wiring by going between the joists in the open space. Use a fish tape to go up through the top plates of the wall and to the lights then drill the wall studs to get the wire to the power box.
Just cut back and abandon the old wiring in the ceiling. |
