Laser Burner For Player Piano Rolls
By Steve Bentley
Questions: What are the diameters of the perforations? How does it look
with a one-inch-long perforation, with bridges or a continuous slot?
I assume you refer to sheet music for timing and note placing. What
length of time does it take to produce a two-foot length of perforated
paper?
I hope it does not set off your smoke alarm.
