Any chance of a copy?

I tried a blade to scrape the roller last night, it is rubber and
normally used for grouting tiles. I'll try it again with the bigger
roller (now installed but I'm going out). I'll also try some mylar as
per Jon's suggestion.

I'm wondering if I should increase roller speed to stop the creation
of the sausages by basically putting more energy into the powder to
whip it up, could get dusty.
