Examples and Demonstration Board of Laser-Cut Flexures in Delrin

Plus a million other projects that fabricator Amy Qian is working on, like a bamboo bicycle frame-building jig

By Rain Noe - December 2, 2019

Digital fabrication, machining, woodworking, bicycle making, welding and sewing: All skills wielded by California-based Amy Qian, a one-woman fabrication shop.

I randomly came across her blog, specifically this shot of a bicycle frame-building jig:

She made it to repair her bicycle, which was run over by a car (without her on it); the frame was destroyed but the components were fine, so she fabricated a new frame out of bamboo.

Then I saw this salt shaker she whipped together out of Delrin, polycarbonate and a brass fitting:

Next, a step-by-step tutorial on how to repair a DeWalt planer using a sprocket from an old bike rear derailleur:

On her Instagram I found a bunch of functional mechanisms that she made with a lasercutter and Delrin:

She's put together a sample board featuring a variety of these flexures for demonstrations:

Check out more of Qian's projects on her site, YouTube, Twitter and Instagram.

I’m a lapsed industrial designer. I was born in NYC and figured I’d die there, but a few years ago I abandoned New York to live on a farm in the countryside with my wife. We have six dogs.
