Double Punching Diskettes

For 5.25" Diskettes, a friend made me a template by taking a piece of plexiglass and punching the holes as a guide in it. I used that template to mark the disk with a silver pencil (not a lead pencil, but a coloring pencil with some wax in it) and then used a regular hole punch to make the holes. Another friend had a metal template made from some thin metal that was bent over so that a disk could be inserted into it, the holes marked with a silver pencil and then punched using a hole punch. I rarely had a DDSS diskette fail on either side. And never had a DSDD disk fail. Though I usually bought Verbatim, Maxell, Elephant or Wabash disks. Even BASF floppies were ok. Though BASF Floppy drives were AWFUL. I did (and do now) have a Wangtek Flippy Drive with the Percom label on it. This drive didn't need extra holes punched since it had two sets of sensors mounted in the drive. You just flipped the disk over and it worked. I'm amazed that I used to think paying $30 for 10 180k diskettes was a bargain... Al Phila, PA
