Nothing new in that at all, Wheelwrights have been using a tool called a 'Traveller' for centuries.

Greenie,
Maybe I'm missing some thing here. But I didn't see or hear Mirock say it was new.

Age of an object has little to do with utility, nothing new under the sun notwithstanding. Greeks and Romans used measuring wheels, before GPS at least a third of European drivers had a map reading opisometer. Naval architects, surveyors and bill of material schedulers use them today. It's all about the increments.
This is a terrific demonstration of design and somewhat intricate processes, in a CNC router. A machine I'd never before considered worth adding to my shop.
Neither K&T Rotary Head or 2 axis CNC; sufficiently agile for compound engraving. The processes themselves were watchable, the finished product is professional.
Compared to fidget spinners and live models that have no useful ability, this is superior.

Curious, if he's in the Ukraine, why are the wheel intervals divided into sixteenths? Also, I wonder if he took into account the thickness of the O-ring when laying out the scale ?

Wondered about that also, imperial increments, English characters and spelling. The O-ring too, until demonstrating the divisions indeed fell on the scale correctly. Most O-rings are compression or transfer molded. They are very round and consistent round cross section, with reasonable density through out. I'd bet he worked from the plexi disc out, first adding the O-ring for correct circumference with a certain degree of stretch, to 'calibrate'. It's a nice neat project. Wouldn't build a house with it, but checking pipe circumferences, heck yes.
I'm on my 3rd pocket Pi pipe tape, at ~3/16th's wide, awful fragile, compared with replacing a nicked O-ring.

Superb craftsmanship a well edited video. I figure the measurement format is primarily targeted towards, you guessed it the American marketplace. Americans have a tendency to desire things not ordinarily thought of as being a necessity.

This guy makes really nice tools. Lots of contrasting woods, brass, finely finished measuring tools. Compared to our guys, aesthetically his style is like Mikhandmaker or Christophe Mineau or Brendon. Here are a few more of his tools we've featured over the years. Go and drop a comment on his YT and you might be able to get him to show up here.

Yessiree!
That's pretty craftsmanship.
Thanks, Jon!

Yup, probably. At the same time, there's a lot to be said for having more than one solution. 'We' [HMT.net] don't seem like one trick ponies, all have co-mingled interests; some that run long enough for a series of projects and that's it. I'm guilty, but hate to give up the capability, for lack of a crystal ball.
