yesterday I had some spare time:
piece of plywood
skateboard "truck" (axle, axle mount, bearings, wheel=hub)
7 Compact disks
10 bolts + nuts
16 washers
4 bolts +nuts for holding the truck to the plywood
stacked CD's, cut 4 holes on outer edge (for bolts, to hold CD's
together)
2 holes on inner edge (connection to hub)
5 CD's need their inner hold widened.
put it together. blew on it with the compressor.
approx 4000 RPM
Ok, it wobbles. badly.
today, I went ahead and remade the CD's,
drilling them closer to precise.
approx 8000 RPM
12V no load (with a 6volt motor)
6V with load, 2amps output.
So, I decided to add ONE nozzle:
1/8" inner diameter aluminum tubing
2X4 wood supports
approx 10,000 RPM
8volts, 2 amps loaded
measured with digital multimeter.
