I have seen pictures of tool post mounted steady, that had brass or broze ring that provided bearing surface for slender rod to pass trough, different ring for different stock diameter. traditional finger aragement might not work for very small work.
There was also a HSS tool bit set (with set screws if I remember correctly) to size the this slender rod to certain diameter. I belive clock makers use it. The big idea was not to use lathe slides to set the cutting depth, but move the tool bit within the tool holder.

Only reference I could find was a bit different...hope this picture shows to you.

Pekka, I think the phrase you are looking for is box tools. A Bing/Google image search for "lathe box tools" shows lots of examples. ME in 1940's ran a whole series of articles on making/using these as well.
A different example is here: http://www.myford-lathe-tools.co.uk/myford/Small_Diameter_Turning_Tool_SDTT_for_M.html
