Step 2: Disk Holder

  • place the ball bearing to the axis (must be fit perfectly)
  • add instant glue carefully
  • place (the other thing with the screw) (must be fit perfectly)

Step 3: Bearing Holder

  • place off the paper mold

Step 4: Cover

Picture of Cover
  • screw 4 screws (adjust the right height)
  • place 4 magnets at the top off the screws

Step 5: End

  • connect it with a power supply.
  • the motor must run opposite the disc's screw

this runs on 32v (printer's power supply/motor)

i would guess that the melt glue that is used to hold the axis would get warm from friction and get out of shape?

A more heat stable solution in the same spirit is some self setting silicone rubber perhaps, (or a piece of acrylic with a hole drilled).

Otherwise I like the project a lot. Good job!

You are right, until now it is ok but it could have better materials

thanks a lot!!

Nice idea, though a simple gear would help to lower and hide away the motor and while you are at it, a suction fan underneath the board to avoid the dust getting everywhere would make it just perfect.

thanks for the idea ..the dust is a problem!

better with gears or belt, but i don't have ! this i make is easiest...

one problem i had last year was cutting the same width a few times, a few holes to mount a guide (a metal piece you'd mount a cd drive with in a pc does the job) helped with that.
