Now that IS interesting Shane. It would be very stable and fast (at least 3600 rpm, up to 7600 rpm depending n the drive). Great for small work like you're showing in the diagram. Should work great. I have a couple of old drives sitting around. That would be fantastic for doing some extra-fine "bench grind" work.
Question: how do you power it?
The computer power supply probably. Which BTW can make a nice power supply for projects or other items. They put out 10volts on one side and 5volts on the other with 2 ground leads in the middle.
Hmmmm 5v huh? Just right for a 5v mini-amp board. : )
That's right and a steady 10volt would be fine for all those 9volt amps and pedals.
Your right sir. I was mistaken.
Bit like putting a doggy door on a submarine,no torque,and the sawdust and metal filings will be bound to corrupt your data, and mess with files eventually
Silly, you back up your files before doing this!
