   Sounds like you've already got tools to do what the watchmakers lathe
will do ...

------------------
Maybe, I don't know if one will do something I need better than what I have; 
the plain bearing, leather belt drive 10" doesn't spin very fast and the AA 
has a bent and imperfectly straightened spindle, their common ailment. A 
comparison of watch and mini lathes said the watch lathe's main advantage 
was being finger safe for close-up work, but so are 5C collets. The Multifix 
tool post lets hand-ground HSS bits in Armstrong holders enter a tight 
recess at a variable angle about as well as a lantern post so I don't think 
a graver would have any advantage there.

I just dug out my spare 5C collets to inventory them and found a pot collet 
bored 2", exactly what I need to complete the steel bandsaw blade guide 
rollers for the sawmill. Aluminum rollers are showing wear.

The Sherline was suggested as an alternative to a watch lathe. I had one in 
my lab at Mitre and wasn't impressed with its feel or capacity, even for 
small electronics work. To me the Prazi clone was a reasonable minimum for 
what I was doing. Despite its 1920's design the ergonomics of my South Bend 
has spoiled me for other machines I've tried, like a Smithy Granite.
