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.
