I took a Yankee screwdriver and turned and drilled one of the Philips
bits into a punch.  It has a hole out the side for the chad to exit.
The drive has a nice finger grip at the "punch" end to guide the
device, and pressing lightly will rotate the cutting edge and create
a very clean hole with minimal dulling and warping of the paper.

Perhaps I should offer these to the PPCo. for the budding 'Johnny
One-Note' roll arrangers.

I taped six derelict QRS rolls together and coded them for the Ampico B
years ago when I made this device.  I had marked lines on the coding
tracks as the roll played through the piano several times.
