Jack Breen's comments regarding X-Y laser cutting of music rolls in
MMD 16.04.23 are well taken.  I believe he is referring to the laser
perforator owned by Don Neilson and operated (at one time) by Frank
Himpsl under the name Valley Forge Music Roll Company.  I do not know
the current status of this operation.  Jack's comments are well-taken,
particularly with respect to fire suppression.  I thought that I had
heard that the VFMR perforator used nitrogen flooding to minimize the
chances of this type of hazard, but perhaps it did not.

As mentioned in MMD 16.04.22, I would propose a "thru-put" inert gas
floodable chamber for the punch media.  Whether this can be designed
in a way to be cost-effective remains to be seen.  But if it can be,
I believe multiple copies _can_ be run simultaneously.  In fact, this
_may_ be the only way a flooding technique can be made cost effective.

On the cutter I use, it is possible to set some cutting parameters to
take into account the media flammability, and allowing accommodations
for materials which have a tendency to melt vs. those with a tendency
to burn.

When possible, it is indeed preferred to use production stock wider
than the finished width, trimming it at the same time as the perforating
for maximum accuracy in horizontal registration.  If I find the time to
try to set this up (for my own personal use), I will initially be using
some new-old stock Auto-Typist blank paper which is pre-trimmed to
11-1/4"width.

If Gene Gerety is still around (his newest MMD entry seems to be in
2002) I would welcome contact with him and exchange of "corporate
knowledge" to preclude reinventing the wheel.
