Double Punching Diskettes

...
   For 5.25"
Diskettes, a friend made me a template....
 I used that template ......
 Another friend had a metal template.....  I think I eyeballed a few of them, but
also used another floppy as a guide. 
Gordon French? peddled a brass template.  Almost as easy to use as using
another floppy.

Of course, those who know me know that the BEST template was the
"Berkeley Microcomputer Flip-Jig".  It was available in both 5.25"
and 8".  It was a plexiglas pocket that permitted markeing both
sides at the same time.
The "deluxe" models of both had a peg and donut for putting on
center hub reinforcers.  EARLY DD 5.25" needed them.  And then
they stopped putting them on with the HD disks.

  > I rarely had a DDSS diskette fail on either side.
And never had a DSDD 
all the "failures" that were reported to us were traceable to other
causes, such as SAND in the drive!
