Another generous helping of Fun With Cables. Today was the day I selected to pull a new cable to the porch light. And it shouldn't surprise anyone who has read any of my previous posts about my house to know that it didn't go as smoothly as I hoped.
First of all I found that the cable, an old armored cable, went through the outer face of the brickwork at a funny angle. The angle I could get it to through the inner face didn't give me a means to pull it with any force. So I had to chisel away some of the inner face of the brick. Then it still wouldn't give much, so I twisted it back and forth trying to break the seal between it and the cement on the outer face of the wall. Of course the outer face of the wall was inside the cavity of the porch so I couldn't get at it without dismantling parts of the porch. I really didn't want to get into doing that.
Having managed to pull and nudge and torture the cable enough that it had given about four inches, I took another look at the outside end of it. I poked it up into the cavity (with the new cable looped and taped to it) and then gave it a good pull from the inside. Much to my surprise it suddenly gave, and moved about three inches in one pull. Once I'd got to that stage I could give it another pull, and before I knew it I had a nice white cable in my hand, and the whole of the old armored cable was inside the house.
So now the armored cable is gone, four ugly joins in knob-and-tube are gone, and another ten feet or so of elderly cable is removed. The wiring situation inside is perhaps still best described as "suboptimal" but at least from here I can press forward with everything, a bit at a time. Until I get to the other porch light all the electrical work I need to do is inside the house, which isn't a bad place to be.
