Interesting. Not sure a single constriction (saw cut into bored hole) is sufficient clamping around the post for a large lathe. If diameter is size for size though, that's tightest interchangeable fit available. Whole design and build is straight forward. The 90° block at 7'.37" is impressive; absolute right way for multiple parts.
100% lathe work; no milling machine at all.

Nice and simple design. But I miss the 'indexing' (?) function. ... that the cutting point is 'exactly' in the same position after de-clamping and re-clamping.

There isn't a true indexing function. This is the basic Van Normon tool post. That thumbscrew adjusts height, but it doesn't index to tool position. It's an improvement over the lantern style, AKA "American" toolpost, but not the ultimate design. Set it up, adjust the height, put a center in the spindle and line it up to the center, and you're done. Next time, or until you need to resharpen a tool, you just bring it to the center point and lock it down.
