[GreenKeys] 33 paper tape punch problem

[Pete Lancashire]

> tape ...  has dried out

One reason it came in a plastic bag.

When I was experimenting with slitting my own tape I also experimented with
oiling the paper by running it through a box that had heated oil in the
bottom
and the tape entered and existed through slots. The length and time in the
box was increased by using rollers /\/\/\/ (up around down around up ....).
A lot more was needed to be done.

-pete down to 4 rolls of 1"
