Test Roll for Aeolian Orchestrelle
By Robbie Rhodes

Joe,  Perhaps I can help you make test rolls for the Aeolian organs.
(But first I must learn how to use the "Template" computer program,
and then I will swamp Matthew Caulfield with output!)

Give me a description of what the test roll should do and a description
of the tracker bar, etc.  I presume that the purpose is to test the
operation of all the pneumatic channels.

"Template" prints marks on computer paper (14.88-inch width) showing
the edges of the music roll and where holes and slots should be cut.
I believe that Matthew then lays previously trimmed music roll paper
on top of the template and secures it with draftsman's tape.
(It's like masking tape but gentler).

Then, with a chipboard backing underneath the two sheets of paper, he
punches the start and the end of the slot with a hand punch.  Later he
completes cutting the slot with an X-acto knife.  (David Wasson built
a knife which holds double razor blades with the proper spacing.)
