How to modify your steering geometry if you're Russian.

This was awesome. Dude actually seems to have a half decent knowledge of what he's doing, but they clearly give zero fucks (especially when he's welding and using an angle grinder with no gloves lololol).

I was gonna rag on the dude for the freehand nature of his approach (especially on the cuts) but then had some memories surface.

I was in my teens, at grandpa's house in WI - he could fix/repair/build anything being an old machinist, and we got onto the baggage cars at airports and how they followed the tractors. He pointed out that hay wagons did the same thing and I realized it was true. I asked how that might be, thinking about trig and so forth from schooling, and he just shook his head and led me upstairs. We got a book, published in 1901 and it showed how to build that steering system via a string and basic pattern - so the wheels turned in at the correct angle whether inside or outside.

Then I remembered the carpenter cutting my roof, and how I'd calc the angles, but he'd just build a little jig and get it perfect, while my calcs were off slightly, even though the numbers were perfect (so it seemed.)

Then I remember the engineers building machine lathes from old engine blocks, depending on only one thing - the 90 degree angle from top of head to piston, getting 1000's of an inch precision with an engine block, old pipes and concrete.

And once again, I don't know shit, but "the greater the need, the greater the performance."

I would love to get my hands on that book. I really enjoy random Do-it-yourself things like that.

It's like someone threw Mighty Car Mods in a blender with a bunch of Russian dash cam videos and a healthy serving of Roadkill. Needless to say, I subscribed.

Back in the 60's, every farmer had it on their bookshelves (or at least the old one's did.) Not sure I could reproduce the title, but it was something super generic, like "Thompson's Guide to Farm Tools" (but that's not it.. just has the same feel as the real title.)

For nearly any type of manufacturing or fabrication, using a prepared jig or form is more accurate than measuring each time. Think about it.

Don't have to. Built furniture for a while except most people don't understand that what I built was jigs and guides, not furniture.
