Sure, but I'm assuming that the original poster doesn't have a
Bridgeport mill at his disposal. But a drill press is quite within the
budget of most hobbyists. I'd think that if you already owned a
vertical mill, you'd know how to work with plastics.
Back in the day, I loved hanging out at the model shop just watching the
action and trying to second-guess the guys there. Building a case with
curves such as side contoured to a 200 inch radius was serious business.
The finished product was in clear acrylic, all ready to go to the mold
Similarly, making the die set for punching sector holes in a 8" floppy
would be child's play for someone with a wire EDM rig in his garage.
But not every hobbyist can afford one.
