Process

Soooo for this build I wan to make a double helix shape. Which means figuring out how to bend wood. Enter kerf bending!

Example #5 from the above link uses a honeycomb pattern of cuts to enable flexing a square piece of wood across multiple axes.

So. much. iteration.

Long story short - none of the patterns I tested did quite what I wanted. Some pieces bent a little. But overall the pieces I ended up with were too brittle, and many broke as I tested them.

PIVOOOOT

Well that didn’t work.

I changed the design from two pieces of wood twisted around each other to a model of a stingray that could drape artfully over a base (still using kerf bending).

In short – that also didn’t work.

When cutting the pattern into the design, my first attempt was too small (the cuts were so close that a section of it started glowing red, and fell off), and my second attempt cracked instead of bending. So in another pivot, I abandoned kerf bending entirely.
