Re: Roll Punching Projects:
By Ed Kigler

Several articles have been sent on this subject over the last few
weeks.  I recently saw an ad by:

    VISION & MOTION SURPLUS
    Marlboro,  MA,

    1-800-471-0747

for a $99 linear motion mechanism with a frame, 15 inch motion,
.005 inch accuracy.  I would think that anyone with a 150+ I.Q.  &
computer/mechanical aptitude could connect this item with a surplus
wide carriage printer for vertical paper movement and record hole punch
positions with a simple optical detector.  Replacing the detector with a
pneumatic or electromagnetic punch, he should be able to duplicate the
punchings on a blank paper roll, or compose his own music on the
computer.  By connecting two of these units together, you could
duplicate a roll directly.
