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).





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.

lasers are cool,therefore it automatically makes them the right choice for everything! ;.-P

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

try making this laser to make the holes. only $60.00 total cost.


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