Laser type and power to cut holes in white paper? Answered

I am interested in building a machine to make pianola rolls. Pianola rolls encode the music in the the form of holes punched in a roll of paper. The holes are usually made by a metal punch or series of punches. I would like to make a unit that uses a laser to cut the holes (about sixteenth of an inch diameter).

Thanks

Andy

Why use a laser ? You'll struggle to find anything that can cut paper like pianola paper for less than a few thousand dollars.

WHy not make a CNC punching machine ? That'd be much more practical. And a lot cheaper.

In this case, lasers are too cool to do anything practically....

And faster.  And most likely it would make cleaner holes, given the right punch.

Pianola roll paper is waaay too thick for the DVD burner laser to do it. Punches are very fast and clean. And cheap.
