5) haberdashery shop has sheer nylon screen material that is 100mesh 40 to 100mesh = FFFFg
anything passes 100 is reprocessed
this works for me
there are several caveats # mesh size is only half the story - wire thickness make substantial difference at the same mesh spacing
# how hard do you shake it? mine is till no more drops through - commercial dont do that
# what grade do you need most of ??
I found enough variability in commercial graded powder (brand x to brand y) to easily justify my system
