>> The measurements don't need to be microscopically accurate to tell 
you what to do of course. ie 6.1-6.3. Dosen't matter that much at thsi 
stage of analysis. Just put on a 17mm shank and hammer, pull out a 
capstan and use a capstan boat and move it around till an action ratio 
closer to your choice comes into view.

 Greetings,
    I think this would be a good time to hear from those that can 
distinguish between actions with identical ratios, but different 
knuckle distances, (which, of course, infers that the capstan placement 
is different.)
  Is there a difference between an action with a low key ratio on a 16 
mm knuckle distance and one that has a higher key ratio on a 17 mm 
knuckle distance?
regards,
