How to add a harp to a lamp

My thrift store lamp that you met on Friday had a lot of things going for it, especially after its spray paint makeover. However, there was one thing missing that I didn’t notice until the very end: the harp.

The harp is the little bracket that goes around the light bulb and holds the lampshade.

I admit, I was a little intimidated by the prospect of installing a harp. I hear about a lot of people rewiring lamps, but I’ve never attempted that myself. It turns out it’s not hard. In fact, I just started trying to take the lamp apart and was able to figure it out pretty much on my own.

Step one was to remove the socket from the lamp base. It just unscrewed, and the cord was loose enough that I was able to pull it out a little bit.

The wire was still buried deep in the socket, so I started trying to figure out how to access it. A close examination revealed a seam in the middle of the socket. You can see it partially opened here.

The socket easily unscrewed, and I could see where the wires attached to two screws. I could also see a really intimidating knot. Gulp.

A couple of turns loosened the screws enough to unhook the wires. Quick tip: I marked which wire went to which screw (one’s gold and one’s silver) by straightening the gold one and leaving the silver one hooked.

I was really, really hoping to not untie that knot, but in order to remove the bottom part of the socket–never mind putting on the harp–I had to. With the knot untied, the socket easily slid off and the harp bracket easily slid on.

After that, it was a (relatively) easy process of reassembling the socket. I slid the bottom part of the socket back into place. I retied the knot. (Okay, this was a bit complicated.) It turns out the knot is called an underwriters knot. I watched this animation a few times as I was tying my own knot. I hooked the wires back over their screws, and then screwed everything back together. I had a reassembled lamp that now included the bottom part of the harp.

The upper part of the harp slid onto the bottom bracket and I gave myself a congratulatory pat on the back.

And then I had to choose a lampshade. Last week I asked for your input, white or grey. So what did I end up choosing?

I went with the grey. It was pretty much the universal favourite last week, and I decided that I liked its flared shape best.

And another detail on the basement comes together. Slowly but surely I will finish this space.

Have you ever rewired a lamp? What DIY projects do you find intimidating?

  1. That is pretty awesome! The gray shade is definitely what I would have chosen. I have an old ceramic lamp that we found in the loft of our house when we moved in. I’ve been meaning to do something with for a long time but haven’t gotten around to it yet. Well, it’s only been 7 years….how’s that for “lightening speed” 🙂
