14" hard drive refurb....

You'd be better advised to use a really fine diamond lapping paste as you
might obtain from an industrial supplier. There are fine enough pastes
available that one can lap to a .000003" finish . . . essential if you're
making Jo-blocks, but probably overkill for your task. If you contact an
outfit like Manhattan Supply Corp, which has branches throughout the U.S,
you'll find something suitable and probably in a quantity you can afford.

If you're worried about the head flatness, I'd not try this trick until
you're more sure of yourself, though.
