Re: [ATM] Acculap ...

[Mark Cowan <toolontop@yahoo.com>]

Hi,

I heard around a year ago that the various grades
could be mixed successfully  and yield in-between
grades.  This was according to the manufacturer -
Sutton Scientifics, Inc. in North Carolina - (910)
428-1600).

The available grades don't go anywhere near soft
enough to be useful to me in figuring, though I use it
in machine polishing where it works quite well.  The
option of having them make a custom batch remains
appealing - you need to supply a large sample of pitch
at the hardness you want for them to match.

Best,
Mark
