Buy me a coffee
One person builds this. A coffee keeps the free half of it running.
I build this on my own — the guides, the calculators, the drawings, the code. Every number on the site is time, reading and testing I put in before it went up, and most of what came out of that is free and staying free.
Free still costs something, though: the domain, the hosting, the compute behind the tools. If something here saved you an afternoon or a set of shafts you were about to cut too short, a coffee covers a bit of that.
No membership, nothing unlocks, no name in a list. The site works exactly the same either way — and if you'd rather spend it on vanes, spend it on vanes.
Thanks for reading either way.

Opens my Buy Me a Coffee page, where you choose the amount. One payment, nothing recurring, no account needed.
Where it goes. Hosting and the domain first, then the compute behind the tools.
What it doesn’t buy. Nothing on the site changes either way, and not a kind word about a product. If a coffee could buy a review, the reviews would be worth nothing.
Rather not? Tell me if a number is wrong instead. Being corrected is worth more to the site than the coffee is.
