This Parabolic String lamp is made out of laser cut wood, yarn, and a pendant light kit.

I was thumbing through some vintage interior design magazines and found all these kind of cool examples of Parabolic String Art.

I examined it closely and figured out how the illusions of curves appeared in the string art. I was curious if the same principle could be applied to a curved dimensional object. I tinkered with a few different designs, and materials - the lamp featured in this Instructable was actually the fifth iteration in my design process.

Step 1: Laser Cutting

I designed the lamp, and it's feet in Illustrator. It was a little tricky to figure out a design for the notches along the wheel, I tried teeth vs. holes vs. notches vs. kerf cuts.

It turns out I needed a notched hole for the best way to catch the string. I used a laser cutter to make my cuts into 1/4" plywood, but I think I could achieve the same effect with a band saw and a drill press. (And a lot more time, this cut took 5 minutes on the laser)

I have attached my files to this step -let me know if you need a different file format.

Step 2: Assemble the Lamp.

I used this Pendant Lamp Kit from Ikea. It turns out these aren't sold in California any more, but we had one lying around.

I designed the hole large enough to fit the socket, but small enough to grab the plywood with the coupler in the lamp kit.

Step 3: Fins and Bulb

I added all of the fins to the lamp, one at a time, making sure to connect it all the way into the notches.

After they were all installed, I screwed in the light bulb. Pretty easy step.

Step 4: The String

By far the longest part of the process, was weaving the skein of yarn into the lamp.

I was able to start the weaving with just a single knot that wouldn't slip through the notch in the fin.

I used cheap red craft yarn and wove it up and down each fin, slowly working my way around, over and over and over and over again.

I was able to end with a single knot in the notch, and cutting the extra off. I pretty much used the whole skein for this design.

Did I iterate that this took a long time? It did.

Step 5: Give It Legs

If you want, you can give it legs, they just attach with a tight tolerance in the notch.

Step 6: It Hangs!

I like it better as a hanging lamp. I think it looks more beautiful suspended from the ceiling - it allows the design to sing a bit more.

I will award a 3 Month Pro membership to the first five people that make this project, let me know using the "I MADE IT" button.

<p>would you send me the DXF file please?</p>
How do you change the light bulb if it burns out?
Could you give me the dimensions? I don't have a lazer cutting machine. So I can use the dimensions.
<p>the dimensions are in the .pdf file.</p>
I re-checked the pdf.. I dint find any dimensions. Pls help!
<p>i will make it as i had two laser cutting machines and i will post my creations </p><p>thanks </p><p>this is very good site </p>
<p>Nice work. However I don't have access to a laser cutter. I do however have a scroll saw. But your PDF does not print in a 1 to 1 template. That would be very useful. Thanks</p>
<p>I have updated the files and added a slightly larger model as well.</p>
<p>this is absolutely gorgeous!! i totally love it!!</p>
just dont let heat catch fire
<p>Awesome work! as always :)</p>
<p>OMG.. This is super Amazing. </p>
<p>It looks so beautiful, I love it!! :)</p>
