[AT] Russian Metric uses BSPP

[Cecil Bearden]

20 years ago I bought 6 milling machines from Summit Machine tool 
Company in OKC.  These mills had had the dials removed to use on other 
machines as they were made in china and could not be found in the US.  
While I was in the warehouse/factory, the workers were removing a new 
machine from a shiping container, then removing all the motors and 
electrical equipment and wiring and rewiring the entire machine with new 
Baldor motors and Square D electrical components and the wiring was from 
Del City Wire when they were in the OKC metro...  A lot of work for a 
new milling machine.
