Re: ATM Dumb Newbie Question

["Richard Schwartz" <richas@earthlink.net>]

You did not say if your curve is pre-generated or not.  If the curve is
pre-generated, read the attached paper that tells you how to make a  tool
and pitch lap foundation.   If your curve is NOT pre-generated, then hog out
the approximate curve with a sub-diameter tool, working mirror on top.   I
suggest a 3/4 diameter tile in dental stone tool, but you can use almost
anything-- even a flat rock.   It does not have to be perfectly round.   If
you use a flat rock, you will want to save it as a souvenir, and you may
possibley want to fine grind it and polish it, so try to get something that
will be  beautiful, like jade or agate...
