Hi Chuck
I think it would work but many of the diskettes I have also have a
lining of a cloth like stuff. I have a hard time cutting just a single layer
with scissors.
One can get a piece of drill rod stock quite sharp. I use the shank of a
drill,
only because it was easy to get. The shanks are not as hard as the
drill part.
I do have one problem, even when just cutting the floppy disk against
the die, I still get a few hanging on by a little. Cutting through the
envelope might not provide enough support at the edges to get
a clean cut.
It is worth trying anyway. One might also try a high speed drill
instead of a punch or even a cutting LASER!
Ok, I'm getting a little carried away. Having all the holes cut at
once would improve the through put.

I put some small aluminum blocks where the
optical sensor and
LED used to be. I have detents on the flywheel that correspond
to the locations where the holes should be. I use the shank of
a #93 ( I think that is the right size ) bit as the punch. This
I sharpened such that it has two flukes, similar to what a paper
punch has.
Assuming one had a sharp enough bit, why wouldn't it be possible to
simply punch all the holes straight through the jacket without having
to do anything more than align the index hole in the cookie with the
index hole in the jacket? It might not look pretty, but what would
prevent it from working? Would there be still too much of a burr
left on the jacket that would interfere with the works?
Cheers,
Chuck
