people have successfully granulated 14k, i’ve never heard of
anyone being successfull with 10k. you are very kind to be so
accommodating. anyone else hear of such a thing?
my suggestion would be to steer the customer back towards 22k.
why does the customer request a 10k disk? the difference in cost
of materials shouldn’t be that drastic. is it for color
difference? suggest silver, 800 or 925, this would work.
