[ARC5] [Milsurplus] CW Keying Wheel

[Brooke Clarke]

Hi Richard:

Just a guess:
Something like the Indexing Spin Jig would be used to position a blank disk where the smallest step corresponded with a 
dot.

This one makes one degree steps.
Also see the Vernier Scale sub section:
https://prc68.com/I/UkiahObs.shtml#Dividing_Engines
Economy Model Indexing Spin Jig
A small saw blade whose width corresponds with a dot is used to cur or not cut the disk.

Once you have a disk a different machine could be used to make a copy in much less time that the making the master disk.

Have Fun,
