Yeah, I know.
I see it answers the question nicely, but it is something of a thread ender. "Hey, look. Got it? Ok. Move on." meh. It was a creative idea. I was trying to continue the conversation.

The threads! You're ruining them!
(This is an inside joke. My vet's old front desk lady...now long gone, had made a hand made sign: Keep your animals off the seats. The cushions! You're ruining them!)

Yes! A chain drill. They are very beautiful and effective tools. You put the chain around the back of the pipe and slide it into the slot on the other side of the drill. Then when you use a brace to twist this thing, the threading in that central shaft pulls the bit slowly and steadily into the metal. It really makes drilling very easy and effective. With a chain drill like this, you can drill holes in metal by hand about as fast as with a modern electric drill.

This one might be more difficult.
What are these things? |

It seems like it would be hard to steer. Maybe the roads were straighter then.

They might have only used them on the rear wheels.

Here are two measuring tools I find absolutely fascinating.
The first image is the "old" version, the second and third images are the "new" versions. The question is, what are they measuring ? . |

Cool! I've never seen anything like that.
Is it some sort of estimating device for estimating the board feet of lumber in a tree? |

Basal area gauge. But I don't really understand completely how it works. And especially don't understand the modern ones.

OK, so I guess you count the number of fat trees in the woods. And you use the metal gauge to see how fat the trees are so you know whether to count them or not based on how much each tree fills the window. I'm guessing the prisms work by either completely splitting the image of the trunk if the tree is too small to be counted, or else leaving a little bit attached if the tree is fat enough to be counted.
