This needs clarification and sourcing. He appears to have invented a form of gear-driven cross-slide that could be used for ornamental turning (i.e. in Holtzapffel's distinction of the term, as opposed to simple turning). This was used for the production of guilloché work (still a Russian favourite), specifically for medallions.
None of his innovations seem to have been relevant to engineering or screwcutting work. Nor did his lathe have a compound top slide (i.e. adjustable for angle).
Nor was this machine a duplicating lathe. It could make multiple identical pieces, but each one was made according to the setup, not copied from some master template.
If I have time tonight, I'll check Holtzapffel. Andy Dingley ( talk) 14:33, 17 February 2010 (UTC)

The book Nartov and his Theatrum Machinarium (ref added to article) has a diagram and description from which it is clearly seen that Nartov's copying lathe indeed copied from a template to a blank (in scale; the pattern was larger to provide for fine detail). A probe traced the template and the cutter did the cutting accordingly. Of course one can write "according to the setup", but the setup was just the insertion of the template. - Altenmann >talk 17:58, 6 August 2023 (UTC)
