John,
If I can get the shop straightened up a bit in 
the next couple of days I will try to show a 
00-90 being cut on the Derbyshire(tiny), the Griz 
9x20 (middle size), and the Monarch 10EE (just right).
Most people are more impressed with the 10EE 
making the tiny screw than they are with the 
smaller lathes.  I guess it just looks out of scale.
By the way, I can make a 000-120 (.034 dia) but I 
don't have a nut to test it with.  I guess I 
could make a 000-120 tap and make a nut but that 
wouldn't prove that it is actually to spec.  I 
thought about boring the thread but my attempts 
at making a boring bar with a .010 shank were pretty much a failure.
I searched for a place to buy a few 00-120 nuts 
but the places that sell them like to move them 
in very large lots.  Pretty cheap by the piece 
but what am I going to do with the other 999.
