Hi Al,
You're a braver man than I. I would never get that
close to a spinning
platter
held to a spindle by magnets.
Hm.. You think that the platter could come lose and
distribute its kinetic energy to arbitrary
directions inclusive cutting my hand, arm, leg, face, or whatever gets into its way?
I have not yet encountered a platter moving from the spindle while operating. The disk is
centered
mechanically and the holding force is quite impressive. It was rather difficult to remove
the
platter after the show: It bent a lot while pulling it only at two points (i.e. with my
two hands).
And if you really get a mad rotating platter, I doubt that it would be really harmful
(except the
very unlikely case that it is torn into pieces ("shrapnel") while spinning: It
has no sharp edges
and is very smooth except for the four screws and the sector slots. In fact I touched the
rotating
platter edge with my hand while taking the photographs. It's not a saw. (Adding saw
teeth to the
edge would make the device much more interesting)
BTW the border between being brave and ignorant or even insane is quite unclear and a
subject of
discussion in uncounted works of classic and modern literature :-)

I have been told you shouldn't let the heads come in contact with each
other like that.
Haha! 898 is the picture I like most! Exactly for THAT reason!
Look at the picture again. Take a
very close look. What is touching what?
Look at the cables and the capacitor in the background. They reveal what is shown in the
picture.
Regards,
Philipp
