I respect the need to keep "ON TOPIC", and the pain it can be for a LONG 
message to appear, in which only a small % may have interest, even IF 
well-ON-topic.  But this particular drill-routing topic has made me wonder:  
Would members like to read a little "article" about how I applied an 
"aircraft instrument motor" designed to run on 115 V/400 Hz. (yes!), 95 
Watts, to make a 12,000 RPM drill-quill?  WAS a project, but the result is an 
amazingly-reliable, precision "drilling instrument", with NO air!    Maybe 
e-mail me direct, or whatever, until I can get a "feel" for whether to 
write/post such.           Jan Rowland
