With brass you really need to make sure that the tool has ZERO back rake. ie the top surface of the cutting edge should be horizontal. After that the usual applys, round edge tools give better finishes than sharp edge tools, so long as your lathe is rigid. I've found that a loose cross slide nut can do a lot of damage to a finish if it allows the slide, and hence the tool, to flex back under load. PK
