I know Angel and others are talking about micrometers for leveling 
screws -- but any micrometer I'm familiar with only has 40 TPI, not a 
lot better than a 10/32 screw, and the screw is a lot cheaper, that's 
why I suggested some of the metric screws with 0.25 pitch (101.6 TPI).  
The laser adjustment screws are generally in the 80 TPI range with some 
in the 100 TPI class, but they are generally $20 or more, whiile the 
metric screws can be put together for a dollar or two. 

Today I was talking to my machinist friend, and he gets  one inch 
micrometers for $10 from
Industrial Tool Sales in Costa Mesa, California   Phone:    
949-631-1586.  These micrometers have tungsten faces and are made in 
China.  They look great.  He may be getting a bit of a price break as 
they buy a lot of tooling, but nevertheless, that is still a very low 
price, and  is the lowest price I know of.

Regards,
Charles Patton
