Wow!  Thanks, Tom!  That is VERY useful to us hobby-folk!

Yeah, I watched a 4-quill CNC PCB-drill with "pods" change its own bits, and 
all SEEMED to be fine, but I just could NOT help thinking, as I walked away, 
"This CAN'T be so reliable ALL the time?!!!"  GOOD to hear it isn't!

Interesting you say the quill motors are electric.  I was told they are 
PNEUMATIC, to run at 100,000 RPM!  Hmmm...
