A 1912 Knot That Keeps the Horizon Honest

Kite Aerial Photography with a Picavet Rig

The camera never left the ground today. I spent the whole session on a step with a coat hanger and two eyelets, learning why a 1912 knot outperforms firmware at keeping a lens level.

Forty Rings In Before the Arithmetic Let Them Close

Chainmaille Weaving

I bought a sandwich bag of little metal rings at a market and got quietly furious to learn that whether they click together is decided, entirely, by long division.

Precision Spinning Top Turning and Gyroscopic Balancing

Returning Boomerang Carving and Tuning

A boomerang that doesn't come back isn't broken — it flew straight, exactly what a hunter wanted 40,000 years ago and precisely what I don't. The fix lives in millimetres of bend.

The Nose Must Outweigh Everything the Wind Can Grab

Model Rocketry

A rocket flies straight for one reason: a pea of clay in the nose. Get it wrong and you've built a very expensive lawn dart. So I swung mine on a string, like 1960 told me to.
