   I don't know how I would QC it   
   though.  I guess the end part would have to be the QC.   
      
   --------------------------------   
   One of the old manual methods Holtzapffel mentioned to create an index plate   
   is to step dividers around a scribed circle and keep adjusting them until   
   the last step equals the first. That task could consume a boy's entire   
   apprenticeship time.   
      
   I made a graduated dial for the crossfeed of my AA lathe, which has a   
   5/16-24 thread. That comes to 41-2/3 spaces per rotation. I'll never know if   
   I got it right.   
      
   Later I was tying up a military satellite uplink with a test pattern of 10   
   million bits at 2400 per second. When the manager asked when I would be done   
   that dividing exercise let me mentally figure the test would run for 4,166.7   
   seconds, or 1 hour, 9 minutes and 26.7 seconds (3600+540+26.7). He gave up   
   trying to confirm it on his calculator.   
      
   Afterwards I was assigned more challenging and interesting design tasks,   
   interfacing an atomic clock oscillator to an embedded computer and designing   
   a 16 bit data acquisition system for a Macintosh, good jobs for a technician   
   without an EE degree.
