Let me guess. This thing has two arc-shaped grooves which look like dovetails in cross section and you rotate one part to take it apart?

Now I'll take a look at the video.

Try wood-cutting "shoulder planes" which are typically metal dovetails joining metal sides and sole around a wooden core, often pretty, and sometimes done in contrasting metals for extra pretty (and making a good visual illustration.)

MUCH simpler.....

No, I think it's machined at a 45-degree angle and slides out.

Even more fascinating to me than the "Doh, that's how they did it" around 30 seconds in, was machining the round pin head later in the video. Never knew you could free hand metal on a lath just like wood!

He was _good_, wasn't he? That was an amazing portion of the video.

He was using engraver tools. They carve metal normally. Take light cuts...

I have turned metal on my wood lathe. Spun metal on a wood lathe. But I made a ball turning tool for my metal lathe. Made ball pulls. Cut brass and then steel. Used HSS cutter or Carbide. Manual turn and move.
