Mike Knudsen said,  "I also published an article in the COAA Journal,
around 2004 or '05, about hand-punching rolls for crank organs.  I use
my own program, which runs only under Linux, and an old-fashioned
dot-matrix printer that can take continuous fanfold paper.  I then cut
out the holes using a hollow center punch plus an X-Acto hobby knife."

One of the key events in getting me started in hand punching was
meeting Mike at the 2006 COAA Rally at Knoebels and hearing him play
his own compositions from hand-punched rolls.  His article was also a
help, although I used other software because I am a DOS/Windows person.
I cut a tuning roll more-or-less as he describes, but knew that the
time spent on a simple foot operated punch would be returned in higher
production very quickly.

Thanks, Mike.  See you at Knoebels this weekend?
