Removing tool marks - Hydrochloric Acid

["linda davis" <lindadavis@xxxxxxxxxxxxx>]

this is great information.  I find hydrochloric acid is sufficent I buy it
under the name muratic acid as industrial cleaner.  it reacts vigorously
with limestome and slate but not alabaster.  I made an acid bath out of an
old ice chest.   the plastic dosn't react to the acid and the airtite lid
prevents fumes from escaping.

that said does anyone have any sugestions for what kind of disks to use
on a bench grinder to sharpen steel tools I have seen many different kinds
each saying it runs cooler than the standard wheels what kind should I get?

-thanks
