A lathe does one thing: it removes everything that is not the part. That is most of the job.

A lathe is one of the oldest machines in any workshop. A bar of metal spins, a cutting tool moves along it, and with every pass a little more of the bar comes away. What is left at the end is the part.
We like that picture because it is honest about where the work actually is. Nobody adds material on a lathe. The skill is in knowing what to take away, in what order, and when to stop.
Most software is cast, not turned
A lot of software is made like a casting: pour the requirements into a template, wait, and break the mould open at the end. You get the general shape, plus seams, bubbles and rough edges that someone has to file down later — usually the customer.
Turning is different. You see the part the whole time. Every pass is small, every pass is measured, and if something is drifting out of tolerance you notice on the next cut, not at the end of the quarter.

What that means for how we work
It means we start by measuring the stock: the problem, the users, the constraints. It means the first thing we ship is rough on purpose, because a rough cut that is real teaches more than a polished plan. And it means we build in weekly passes you can see, click and question.
Most of all it means we care about tolerance — the small, boring numbers that decide whether something feels right. How long the page takes to load. Whether the button responds the instant you press it. Whether the app still works in a car park basement.
That is the studio. Bring us the rough stock.
