Seiko Paper
***********
This page documents the trimming process of the Seiko Dpu-414 Dpu-s445
thermally sensitive paper for use in the HP-85. |Thermal Paper at Amazon|
The paper is 4.4" (112 mm) wide, and needs to be trimmed to 4.22" to 4.23"
wide. (107 mm)

To protect the roll of paper from the lathe chuck jaws, I wrapped it in
a thin cardboard tube, from a toilet paper roll.

The roll of paper is then mounted in the lathe, and the cardboard tube
shows where the cut needs to occur. The cut is done with a hand held
:ref:`Swann Morton Scalpel Handle number 3` and :ref:`Swann Morton Number 11 Scalpel Blades`.
The scalpel must be held so that spinning roll of paper can't push it
toward you. I had the sharp edge facing up, and the blade was applied
to the under side of the roll.

Once the paper is cut to length, I used a normal lathe parting
off tool to trim the central core to correct length
