Cool, thanks.  I want the curve pre-generated to save myself some time, both 
in not having to hog out the new glass myself and in being able to re-use my 
existing tool, which is darned close to my desired curve already.  I'm also 
pleased with how my tool came out and don't really want to make another one 
:-)
