In praise of binder-twine engineering

I grew up in country South Australia, and a lot of my real education happened in my grandfather’s shed. The school of thought there was what I call binder-twine engineering. Binder twine is the tough, hairy string off hay bales, and on a farm it ends up holding together plenty of things it was never designed for.

It’s easy to smile at. But there’s a real philosophy inside it, and I’ve come to think it’s one of the most useful things I ever learned.

Start with what you’ve got

Binder-twine engineering begins with an inventory, not a spec. What’s in the shed? What’s lying around that could do the job? It’s the opposite of the procurement mindset, where you define the ideal solution and then go and buy it. In the shed you look at the problem and the pile of stuff at the same time, and the solution is whatever connects them.

That constraint breeds resourcefulness. You get very good at seeing what an object could be, not just what it was sold as.

Ask what the job actually needs

The second habit is ruthless honesty about requirements. Does this need to be perfect, or just hold until harvest? Does it need to look good, or just not fall over? Most over-engineered things weren’t built by people who didn’t know better. They were built by people who never asked this question.

Make it work, then make it good, and know which one you’re doing.

Iterate in the real world

Shed fixes get tested immediately, by reality. If something breaks, you find out fast and fix it again, a bit better this time. There’s no gap between prototype and production, which is humbling and very educational.

Where it goes wrong

In fairness to the textbook, binder twine has limits. Some things need proper engineering: anything carrying people, anything in orbit, and anything where failure is expensive or irreversible. Part of growing up as an engineer is knowing when twine is fine and when it’s dangerous.

Still, I’ve found the instinct carries surprisingly far, from embedded systems to regulatory approvals to a pitch deck due tomorrow. Understand the real problem. Use what you have. Be honest about what “good enough” means. Make it work.

Nobody in that shed would have called it a methodology. They’d probably find it funny that I do.
