This is great - I'm happy to hear a knowledgeable person speak on just about any topic.

Gorgeous stuff. That binder of available patterns is more drool-worthy to me than all the fun gears and machinery through the rest of the video. The reducing lathe was surprising, though. I'd never thought about how that was done before now, except I knew the original designs were huge. I'm happy to know that there are multiple people who spend time preserving all these fantastic devices.

Nothing rudimentary about those lathes!

Some beautiful guiloches on the Excentro website. Mac only, sadly.

Guilloche made with an Erector Set (Meccano)

A fountain pen barrel being cut by a vertical guilloche machine. Your great-grandfather might've had a fountain pen cut by a machine like this: Back around the turn of the previous century even the cheaper hard rubber pens often had all-over engravings like this.

Nothing rudimentary about those lathes!

And yet, so well-formed.

I don't have anything to say about the content that hasn't already been gushed over extensively in the comments already, so I just have to ask. Is he intentionally rocking a mowhawk, or is that just how the hair fell out over time?

That was great. Thanks!

This is very cool. Coincidentally, my sister is a (retired) banknote scientist, most recently with the Federal Reserve Board of Governors. She was the co-leader of the "big head" redesign of bills back in the mid to late '90s.

I sent the SLYT to her so she can nerd out on it. Unfortunately, she still won't disclose to me all the anticounterfeit measures on the new bills.

"Banknote Scientist"!? Your sister has (had) a very cool job title.
