For running conduit, cable or similar materials through bale walls: take a
two-and-a-half foot piece of conduit and smash one end flat. Clip off or
grind the corners of the flattened end so it is somewhat pointed, and pound
it through the bale wall. Now anything can be inserted into the hollow
conduit. Have your helper on the other side of the wall pull the conduit
through, and the wire, cable or whatever comes through with it.
