Factory Punch Step Intervals
By John McClelland 

I seem to remember several discussions in MMD about the various step
intervals that Duo-Art, Welte & Ampico used when perforating their
rolls.  I've gone through some of the subject matter headings in the
cross-referenced library but evidently must be looking in the wrong
spots. Can anyone point me in the right direction, or heading (oops,
bad pun.)

Thanks,
John McClelland

 [ Wayne Stahnke talked a bit about this in an article titled:

 [ There may be more that's been said on this subject, but I don't
 [ recall.  I'd like to encourage additional discussion on this
 [ topic.       -- Jody
